First Trip to the Putah Creek Reserve, 06-09-21

I got up around 5:30 this morning and was out the door with my friend Roxanne by 6:00 to go check out the trail along Putah Creek off of Pedrick Road. This is located at the western-most end of the Putah Creek Reserve.  There are three other access points that I think I’d like to explore later. (CLICK HERE for more information.) I had never been to any of the access sites before, so I let Rox lead the way. Water in the creek was low but moving swiftly and clear.

We took the part of the trail that went under the adjacent road, and found that Cliff Swallows had built up nests in some of the depressed weep-holes in the cement. According to Cornell:  “…Highway bridges selected in northern California typically were in areas with low urban development, and on structures with undersurfaces containing multiple junctures, water underneath the bridge, and large underpass openings…” 

The males pick the spot and start building, but then both parents finish the work. The nests can be made up of up to 1200 individual mud pellets.We noticed that nests placement seemed to be confined to one side of the culvert overhang and not the other, and speculated that sun exposure may have been an issue. Cornell says: “…There is no apparent preference for direction of nest exposure on any type of nesting site, although west-facing nests receive more direct afternoon sunlight and may be much warmer than nests facing in other directions…”

We couldn’t tell if all of the nests were occupied, but we did see activity in and around a few of them. We speculated that some might be nests with a single baby inside, but it seems more likely that we were actually seeing nests in which one of the parents was sitting on eggs.

We didn’t see any egg shells on the ground, and we didn’t see any “gaping” by the birds occupying the nests when the other parent arrived which seemed to enforce the idea that we were seeing adults both flying about and sitting in the nests. Because it’s almost impossible to tell the females from the males, we couldn’t tell which of the parent birds was which… And when they’d both enter the nest, we couldn’t tell if it was the same bird who flew out as flew in.

Cliff Swallows generally lay their eggs in late May and early June (which is the window we’re in right now), and usually lay one to six eggs.  Both parents share incubation duties. It takes about 23 days for the chicks to hatch.

We were seeing the same trees and understory plants along the creek as we did elsewhere throughout the area, so it was all “nothing new”. Or so we thought. We did find some galls there that I hadn’t seen before, and that’s always a bit exciting. On some of the willows we found some galls of the Willow Mid-Rib Sawfly, a species that has yet to be identified by Russo (but is shown in his new book).

We also found two different kinds of wasp galls on the leaves of the eucalyptus trees: little flattish speckly galls of Ophelimus maskelli that covered the surface of some of the leaves, and mid-rib galls of the Leptocybe invasaL. invasa is an invasive species indigenous to Australia. The females can reproduce asexually, so even though males sometimes show up in colonies, they’re not really necessary except to provide some diverse genetic material into the mix.

Moth Mullein was growing in places, but most of it seemed to be going to seed already. The Moth Mullein I’d seen in other places (such as along the American River) seemed to be just starting to appear. That made us wonder why the plants at Putah Creek were seeming “ahead” of similar plants elsewhere. Microclimates created by the creek might have been one reason.

Mullein, Moth Mullein, Verbascum blattaria [thin stick, white or yellow]

We walked around the creek for about 90 minutes and then headed over to the Woodland-Davis Clean Water Agency facility where the Ibis Rookery is located. It’s still too early for the ibis to be nesting in the settling pond there, but we thought maybe we’d see some Avocets or Pelicans in the water. No such luck. Along the water’s edge we saw quite a few noisy Black-Necked Stilts and Killdeer. No one had babies. I think the Killdeer should be pretty much done breeding by now. but I couldn’t remember if we were early or late for the Stilts.

Both species of bird nest on the ground, and use “scrapes” as the basic shape of the nest cup. Killdeer usually prefer gravelly sites, but the Stilts prefer little islands or other raised areas like that.  If memory serves, I think they lay between around June or July in this area… so their chicks are born right around the time the ibis start moving into the pond. I’ll have to keep an eye out for them as the months go by.

Along a spit in the pond, Rox spotted an usually large grouping of Pacific Pond Turtles. There were about 8 to 10 of them all collected in the same area. A few were basking on the shore but the majority of them were floating in the water with their heads poking up above the surface. Not a Red-Eared Slider among them. We found a few more of the turtles in the slough along the side of the road, so apparently they had a very good breeding season this year. It was so nice to see.

There were only a few damselflies among the vegetation around the pool, and I managed to catch a Tule Bluet by its wings so we could get closer shots of it. And we found a single teneral Variegated Meadowhawk dragonfly, not quite colored up yet. I don’t know if there are actually fewer of the dragonflies and damselflies than usual, or if I’m just impatient and they haven’t all emerged yet, but pickings seem very slim.

There were rabbits everywhere, Black-Tailed Jackrabbits and Desert Cottontails. They obviously had a good breeding season, too. Hah!

As we were leaving the area, Rox spotted a large gopher snake cross the road in front of us. Because the road isn’t used much, we were able to stop, and get out of the car in order to take some photos of the snake. It was maybe two-and-a-half feet long; a handsome honey color with a pale face. 

Coloration of the snakes in this species is actually quite varied: typical spotted versions with a background color from honey, to dark brown, to gray, to red; striped versions; and even albinos.  There are lots of snakes all over the region, but they’re so good at hiding that we very seldom actually see any of them.  So, spotting one, even a common gopher snake, is always a treat.

CLICK HERE for the full album of photos.

We then headed over to Natomas where the Wyndham Heron Rookery is. We could hear lots of baby Black-Crowned Night herons “clicking” in the trees but couldn’t really see any of them. Sadly, there were quite a few dead chicks on the ground (at various levels of development).  Chicks can sometime simply blunder out of the nest, or fall out of nests that aren’t very well constructed, but siblicide is apparently common among the herons.  Larger nestmates bump smaller ones from the nest or suffocate them by “swallowing” the smaller sibling’s head, leaving the sibling near death and unable to compete for food. Yikes!

Dead heron chicks at various levels of development.

As far as we could tell, many of the adult were still sitting on eggs — and on small chicks — so there may be more chicks hatching and feathering up over the next several weeks. 

On the little island in the middle of the pond, the Showy Egrets were still nest building, and sitting on eggs. I saw a few chicks, but wasn’t able to get any really good photos of them because of the distance between the island and the walkway. Rox caught sight of a Green Heron fishing along the shore of the pond, but I wasn’t able to get any photos of it.

Among the insects found we saw several Pacific Forktail Damselflies, a Gray Hairstreak butterfly, and a tiny Heather Lady Beetle.  By the time we finished walking the loop around the pond it was almost 12:30 pm, so we called it quits and headed home.

It was fantastic to be able to get a good walk in after being confined to the house by pain over the last week.  The walk wore me out, though, and I fell asleep sitting up in bed after lunch. Hah!

A Little Drama on a Short Walk, 06-04-21

Ugh! I got absolutely no sleep last night because of the Poltergeist and hip pain. Ibuprofen cuts the edges off the hip pain, but doesn’t touch the nerve pain at all.  Still, I felt I should get outside and walk, so I took my dog Esteban with me to William Land Park.  It was 63° when we got here around 6:30, but warmed up fast. Within 90 minutes it was already 70° outside.

We walked through the WPA Rock Garden and around the middle pool, but I couldn’t do much more than that.

It’s almost impossible to maneuver my cane, my camera and my dog on a leash at the same time, so I’d resigned myself to not getting very many photos. Still, I got a few.

CLICK HERE for the full album of photos.

As we were walking back to the car, I saw a woman in a Wildlife Rescue shirt carrying a large net.  She was going after a black duck — who was paired up with a larger white Pekin duck.  I could see something hanging off the black duck’s bottom and assumed it was a fishing lure or something like that. [I’d seen similar injuries to ducks and geese at Mather Lake Regional Park. More recently, a goose with a longbow bolt impaled in its bottom was rescued.]  I took some photos and some video, even though the action was pretty fast and most of the ducks’ movements were a blur.

The woman chased them around trees and tried to corral them against a planter — but the ducks ran or flew off away from her, just out of reach. Eventually, she was successful in catching the black duck, and just as she did so, three or four other ducks ran at her (as though coming to the black one’s rescue).  None of them got near her, though, and she was able to get the netted bird by its wings and carried it back to her vehicle. My drama for the morning.

All the while this was going on, Esteban was watching, but made no attempt to chase the ducks, or bark, or interfere in any way.  I was very proud of him.

When I got home, I checked the pictures I’d managed to get of the black duck and realized that it wasn’t a fishing lure hanging from underneath it. It was the duck’s prolapsed penis. Ouch!  Most male birds don’t have a penis, but many ducks and geese do, and “prolapsed phallus” is apparently something they have to deal with quite often. 

There was even a TV animal rescue show that had a segment on the condition.

This happens when the male ducks “… are unable to retract their male genital (phallus) back inside of their body. It requires immediate attention to avoid complications such as secondary bacterial contamination and irreversible damage. A prolapsed phallus is usually trauma-induced, but can sometimes also be a clinical sign related to venereal disease or duck plague. When the phallus is outside of the body, it runs the risk of becoming enlarged and swollen, dry and ulcerating, and necrotic during advanced stages… But since (unlike mammals) a drake doesn’t use his penis for peeing, but only for procreation, he can get along just fine without it.” Poor drakes!

I walked for about 90 minutes, but because I didn’t get very far, I didn’t count this toward my #52HikeChallenge.

The Other Gristmill Trail, 06-02-21

I got up at 5:30 this morning and headed over to the Gristmill Recreation Area, getting there around 6:00 am.  It was 59° when I arrived there, but it warmed up to 70° before I left.

I walked over to where I normally see the Western Screech Owl, and was happy to see her — but she ducked down immediately when a loud Scrub Jay flew down in front of her.

I then walked on the longer trail on the opposite side of the parking lot. I hadn’t been on that one before, so I didn’t know what to expect, really. It was more “wild” than the other trail with lots of trees, plants, and wildflowers (some still surviving in the heat) that are not seen on the shorter trail. It was also flatter with direct access to the river in a few spots.

The little footbridge on the trail

I was surprised to see so many Elegant Clarkia flowers still in bloom. And it looks like there had been several stands of a kind of phacelia (caterpillar flowers) there — which I’ll have to keep an eye out for next year.

Elegant Clarkia, Clarkia unguiculata

There was much of anything on the water, although I did see a Great Egret and the mama Merganser with her red-headed babies. She’s still got her four little ones, so she’s been pretty successful in keeping them alive and safe.

Common Merganser, Mergus merganser

I found quite a few galls on the trees including those of the Black Walnut Pouch Gall Mite and the Willow Rosette Gall Midge.  The rosette galls, this time around, were new ones, still all shiny and green.  New-to-me galls included those of the Smooth Petiole Gall Sawfly and Willow Fold Gall Sawfly. 

As their names suggest, the petiole galls were at the petiole (the point where the leaf attaches to the plant) of the willow leaves, and the fold-galls were, well, folded. In some of the fold-over galls, I found aphids being tended by ants. I think the aphids were secondary dwellers, though, having taken over the folds after the sawfly larvae hatched out.  I’m not sure, though.

Formicine Ants, Subfamily Formicinae, tending to aphids

On one of the cottonwood trees, I saw a collection of about a dozen “things” hanging down from the branches.  They looked like bushtit nests or maybe masses of bees, but I could tell they weren’t. They were made of plant material. But they weren’t like any of the hanging seed pods, and there weren’t any of them on any of the other trees. They were — and still are — a bit of a mystery to me. I think they might be panicles of seedpods that have been taken over by some kind of fungus or insects — like large leafy galls. More research is required…

Among the insects, I found a single specimen of a tiny planthopper, Agalmatium bilobum.  It’s an “adventive” species, which means it’s not native but also not very well established yet.

Issid Planthopper, Agalmatium bilobum

I also found several examples of what I think is a kind of “moth leaf tier” on an Arroyo Willow. They were collections of leaves with a dead leaf in the center surrounded by several live leaves — and I think they hid moth caterpillars of some kind.

I opened up a couple of them, and found that whatever had been inside the leaves was now long gone, leaving just plant material and old webbing behind. I’m still searching for a more specific ID. The construction of the things was really interesting to see, though.

CLICK HERE for the full album of photos.

Although I didn’t get any really good photos of it, the most interesting moment on the trail today was seeing a female Nuttall’s Woodpecker foraging in the bark of a tree, while below her, near the ground, was a female Downy Woodpecker foraging on Mugwort plants.

I’d never seen a woodpecker foraging on plants before, so I had to look it up.  For the Downy Woodpecker, it’s rather unusual (used only about 2% of the time). I assumed the bird was looking for ants more than plant matter itself.

Fun fact according to Cornell: “…Percussion not a means of securing prey, but rather a means of locating prey by rapidly tapping along a branch or trunk, presumably in order to hear resonance produced when tapping is above tunnel of a wood-boring insect…”

I was out on the trail for about 3 hours and then headed back to the car…and it was from the car when I got photos of House Finches and Lesser Goldfinches. Always have to keep my camera at the ready.  This was hike #50 of my #52HikeChallenge.

All Around Yolo County, 05-28-21

I got up at 5:30 this morning and met up with my friend/fellow naturalist Roxanne to go see what was out and about in Yolo County. We had planned to go to the Putah Creek Riparian Reserve somewhere along the line, but we got waylaid by other sights and destinations, and then it got too warm for us to be walking around outdoors.

We went along Roads 105 and 30 to look for the hawks and other birds that had been reported in the fields there, then we went to the Yolo Bypass Wildlife Area, then we headed over toward the Putah Creek access, but ended up in the Häagen-Dazs Honey Bee Haven instead. At every place stopped, we saw something interesting and unexpected, and that’s always fun.

Roads 105 and 30 in Yolo County

On our way to Road 105, we saw a large, flat-faced, light-colored bird fly across the highway in front of us. We assumed by its GISS [general impression, shape and size] that it was an owl, possibly a barn owl, but we didn’t know for sure.

Rox had been in the area the day before, so knew where to look for the birds in the fields along Road 105. We pulled up onto Road 30 (where the traffic was practically nil), and got out of the car to take some photos and video.

We found a sizable collection of birds in one field, and although they were all pretty far away from us (and we didn’t want to trespass into the field itself) we were able to identify the species of the birds. 

Along with lots and lots of Swainson’s Hawks (all of them sitting down, partially hidden by the grass), we could see Great Egrets, Snowy Egrets, Black-Crowned Night Herons, Cattle Egrets, Great Blue Herons, crows and ravens, Red-Winged Blackbirds and Brewer’s Blackbirds all standing or flying in close proximity to one another.

There had been lots of reports of large gatherings of birds in the ag fields lately because some of the fields were being flooded, and that caused all the ground-dwelling mice, voles, and insects to come up in order to flee the water…then had to run the gauntlet of hungry birds. Swainson’s Hawks take both small rodents and insects, so their sitting on the ground was not uncommon for them. They’ll actually run on the ground after prey if they have to. 

And it was just Swainson’s Hawks out there, no other species. I think that’s because the Swainson’s often gather in large flocks which may be intimidating to other hawks. In one spot alone, I counted 18 Swainy’s.

According to Cornell: “…These elegant gray, white, and brown hawks hunt rodents in flight, wings held in a shallow V, or even run after insects on the ground. In fall, they take off for Argentine wintering grounds—one of the longest migrations of any American raptor—forming flocks of hundreds or thousands as they travel…”

In the field, the various birds on the ground seemed to be fine with their nearby neighbors.  The hawks didn’t bother the herons or egrets and vice versa. There was one young Swainson’s Hawk, however, who had somehow aggravated a group of blackbirds and a tenacious Kestrel, and was being chased back and forth and around the field. The hawk was crying all the while it flew, as though begging for help, but none of the adult hawks came to its rescue. It eventually landed in a tree on the edge of the field and hid itself among the leaves.

CLICK HERE for the full album of photos.

As we were walking along the edges of the field, I found an owl pellet… and also saw one of the female Brewer’s Blackbirds take some grass to her nest in the top of a tree.

To try to see more of the birds in the field from a different angle, Rox drove further down Road 30.There we saw a solitary female Wild Turkey, and some young crows going through/coming out of a major molt.  “…When crows molt, the old feathers can appear brownish or scaly compared to the glossy new feathers…” And some of these looked very brown.

We then turned the car around and drove down the other end of Road 30, almost to where the paved road gave way to dirt and gravel. We were surprised to find that some of the folks who lived nearby did some “native plant planting” along the edges of the ag fields.  There were a couple of very nice stands of Showy and Narrow-Leaf Milkweed plants, most of them just starting to bloom. Along with the honeybees, we saw a Green Lacewing, and lots of Blue Milkweed Beetles.

The beetles are a dark metallic cobalt blue with black legs and antennae. They live on or around milkweed throughout their lifecycle, eating the leaves (and sometimes the roots of the plant), having sex, and laying eggs. The larvae can “skeletonize” the leaves of the plant, but that action doesn’t kill it. It simply goes dormant until the next season. Although these beetles have the ability to launch themselves (like click-beetles), none of that did that while we were looking at them… not even when we brought them close to the eyes of our cellphone cameras.

We found a couple of the honeybees that had been trapped by the milkweed and died. Milkweed plants are interesting in that they have a variety of unusual boobytraps built into them that other plants do not. Besides their sticky latex (the white sap that drips from the plant when it is damaged) which can trap a variety of insects, the milkweed flowers themselves can also be dangerous for pollinators.  

Rather than offering up its pollen on upright visible structures called “stigmas”, the milkweed flower has its pollen hidden inside special little crevices called “stigmatic slits”.  When a pollinator, like a honeybee, lands on the flower and walks over its surface to drink the flower’s nectar, the bee’s feet slip inside theses stigmatic slits.  Pollen inside the slit affixes itself to the bee’s feet, and when the bee moves to another flower, it carries that pollen with it. Transferring the pollen and putting its feet into the stigmatic slits of different milkweed flowers completes the process of pollination.

Occasionally, however, the bee’s foot may get caked in so much pollen that it simply cannot get its foot out of the slit. (Think of putting your hand into a jar with a narrow neck so you can grab a handful of candy at the bottom of the jar. Your candy-filled hand may then be so full and wide, it cannot get through the jar’s neck, and your hand gets stuck inside the jar.)  

A dead honey bee caught in the slits of a milkweed flower. Note the pollen sac attached to the foot it managed to get out.

Some bees actually amputate the trapped foot in order to escape. But if the bee is unable to do that and cannot manage to get its foot out of the stigmatic slit, it will eventually succumb to starvation and dehydration and die.

When we turned the car around again to head back to Road 105 (and onward toward the wildlife area), we found that the hawks had taken to the air in a swirling, dense kettle of over 50 birds. I’d never seen anything like that. It was amazing to witness. Flying in huge kettles is not uncommon for the Swainson’s Hawks.

According to Cornell: “…When it comes to forming kettles, Swainson’s Hawks are overachievers: they form flocks numbering in the tens of thousands, often mixing with Turkey Vultures…[other hawks and kites)…”  These giant kettles, of course, are during their migration to Argentina, but still… Wow!

We then went to the Yolo Bypass Wildlife Area. There is virtually no water on the ground right now, so there was “nothing” to see. There were doves in several locations, but they were really the only birds, besides finches that we saw out there. It would have been a totally boring and disappointing stop had it not been for the dodder. We had never seen dodder in bloom before, so when we realized the stuff at the bypass was dense with flowers, we were super-excited.

Roxanne did a write-upon the stuff for Facebook which was excellent, so I’m quoting her here: “…Ah, Dodder. It’s the golden, orangey or reddish silly string of the plant world. That’s right: a plant. Dodders have roots (temporary), leaves (often reduced to scales), flowers and seeds. Dodder is parasitic. Although it sprouts from seed, it mostly or completely lacks chlorophyll. Consequently, the new sprout must find a host between 5 and 10 days from sprouting or it dies. The sprout swirls around as it grows and once it touches a host plant it buries haustoria (knoblike organs along the shoot) into the host stem, drawing water, carbohydrates and minerals at the expense of the host plant. As well as “starving” the host plant, dodder is also implicated in the transmission of certain bacterial and virus diseases. Thus nourished, the dodder’s roots die and the dodder spreads out in a mat moving from plant to plant, branching as it goes. Broken bits can continue to thrive if haustoria are attached to the host plant. Animals, humans, or equipment moving across a dodder mat can thereby spread dodder to new areas.

            “Flowering dodder can produce thousands of seeds that can live in soil for up to 10 years. In many native habitats dodder is not considered particularly harmful. But in an ag context dodder can cause significant economic harm, especially to alfalfa, asparagus, citrus, clover, beans, melons, peppers, potato, tomato, safflower, sugarbeet, field bindweed (Convolvulus arvensis), lambsquarters (Chenopodium album), and pigweed (Amaranthus species). It is easy to see why Dodder has enjoyed a variety of common names including love vine, goldthread, devil’s-guts, devil’s-ringlet, devil’s-hair, hellbine, hairweed, beggarweed, scaldweed, strangle tare, strangleweed, and witch’s hair.

            “CalFlora lists 31 species of dodder in CA, and only 5 are non-native (often arriving here in contaminated seed or in horticultural soils). Dodders can be found in California ag fields, forests, canyons, salt marshes, deserts, beaches and mountains up to 8200’. CalFlora lists two species here in the valley, Cuscuta campestris (Field dodder) and Cuscuta pentagona (Western field dodder) but several more species can be found in the Bay Area and into the foothills north and east of Sacramento. My frequent naturalist partner, Mary Hanson, and I first spotted a hillside of dodder two years ago in the lupin and poppy along Wilbur Springs Road about half way between the bridge and the gate to Wilbur Hot Springs. The next year we found less there but a whole hillside along Bear Valley Road not far from the bridge intersection. We ID’d this as Cuscuta californica (California Dodder) but now I’m not so sure. More study for distinguishing species is needed.

            “…Not far along the auto tour near the marsh viewing stand is a largish patch of golden yellow-orange dodder on the right side of the road in the Small Melilot (Melilotus indicus), Prostrate Knotweed (Polygonum aviculare), Bisnaga (Visnaga daucoides), and Fennel (Foeniculum vulgare). This is the first time we’ve seen the dodder in the bypass and the first time flowering. The shape of the tiny pale flowers grow in clusters and their shape and growth pattern help distinguish species.

            “Look for dodder when you are out and about and see if you can also spot the hautoria and tiny flowers. I’d be interested in hearing where else naturalists are finding it. FYI, dodder seeds are considered an herbal remedy, especially in Chinese and Korean herbal medicine. A quick Google search revealed lots of sources for seeds, extract powders, and tinctures…” Sooooo informative.

Charlie Russell, one of my former Certified California Naturalist program graduates and plant guru noted: “Dodder spreads vegetatively, so when they grade the ponds in the Yolo Bypass it spreads quite readily. Some years there can be multiple acres of solid dodder out there…”   Whoa!

There were Cabbage White butterflies all over the place. They’re “nervous fliers”, which means trying to get a still shot of one of them is tricky. The species was “accidentally introduced” in the late 1800’s. I got several photos of one foraging on mustard (Brassica rapa).

Studies seem to indicate “…some flowers, like Brassica rapa, have a UV guide for aiding nectar search for the butterfly where the petals reflect near UV light, whereas the center of the flower absorbs UV light, creating a visible dark center in the flower when seen in UV condition. This UV guide plays a significant role in foraging…” Cool, huh?

After the bypass drive, we went on to the Häagen-Dazs Honey Bee Haven, which was right in route to the Putah Creek access area. Because the pollinator garden is only an acre and the paths are well drawn, it’s easy to walk around it. The street on which the garden is situated has a lot of tall olive trees along it, so there are a lot of shady places to park.  The garden is open from dawn to dusk year-round and admission is free. Rox had never been there before, and there were picnic tables in the shade of one of the old olive trees there, so we stopped for lunch and walked the grounds for a bit.

CLICK HERE for the full album of photos.

All through the garden are paintings, sculptures and mosaics (most of them by local artist Donna Billick) that have been donated to the garden from local artists and from the art department at UC Davis.  For art students who need science class credit to graduate, they can take an art-and-science fusion class that lets them do something creative for the garden while they learn about the bees.  So there’s something new in the garden every year. The standout sculpture is of the giant “Miss Bee Haven” bee.

According to author Kathy Keatley Garvey: “…Miss Bee Haven [was built] using rebar, chicken wire, sand, cement, tile, bronze, steel, grout, fiberglass and handmade ceramic pieces. The project took [Billick] four months to complete… Anchored with 200 pounds of cement and with six bronze legs drilled into the pedestal, this worker bee is destined to stay put… Billick used lost wax bronze casting to craft the six legs, which extend from the thorax to rest on a ceramic purple dome aster, fabricated by Davis artist Sarah Rizzo.  The purple dome aster is among the flowers in the garden…”

The garden offers suggestions of what to plant in your own yard, how much water each species of plant needs, when they grow, etc. I was most impressed this time around by the lavish kiwi vines covered in their large leaves. Something of a surprise was seeing a Turkey Tangle Fogfruit plant covering an entire planter and flowing down onto the ground. I’d never seen one that was so prolific. Usually, when we come across the plants, they’re relatively small, maybe less than a hand’s breadth. So, to see one this big was kind of shocking.

Turkey Tangle Fogfruit, Phyla nodiflora

Among the flowering plants, we found several species of bees there including carpenter bees, honey bees, mason bees, leafcutter bees and sweat bees. We also saw a few Flame Skimmer Dragonflies. 

By the time we’d finished walking the acre, we were tired… and it was getting too hot for us to walk anymore, so we headed home. We were out for about 5 hours, and I counted today’s trek as hike #48 in my #52HikeChallenge.

Caddisfly Larvae and the Nemesis Bird, 05-25-21

I got up around 6:00 this morning and headed over to the Gristmill Recreation Area on the American River for a walk. I hadn’t been there for a while, so I missed the fledging of the Red-Shouldered Hawk babies there. It was about 57° when I arrived, but the sun came up fast and hot.

I walked the most-used trail and then ventured out a little bit onto the river’s edge where there was some still, shallow water.

On the trail I could see some birds in and around the bird boxes including House Wrens and Tree Swallows. The wrens fill their box full of twigs, so there’s stuff poking out through the entrance hole — which makes it pretty easy to figure out who’s in there.

While I was taking photos of them, a pair of California Quails ventured out from a tangle of wild blackberry vines and scuttled across the trail. Just one male and a female; no harem and no babies.

CLICK HERE for the full album of photos.

As I walked along, I could hear the chattering sound (called a “rattle call”) of Belted Kingfishers in the trees along the riverside. They’re like my “nemesis birds”: I can hear them a lot, but seldom get to get any photos of them because they’re shy and move so quickly. I was lucky today, though, two females landed on the same branch, and I was able to get some photos and some video snippets of them.

A female Belted Kingfisher, Megaceryle alcyon

Kingfishers excavate and live in burrows in the banks of the river. I think they’re nesting cavity may have been below where the females were sitting, but I’m not sure.

I was taking photos of one of the Kingfishers when a bird group went past me on the trail. A few second later, one of the men in the group came back to me and asked me my name. I told him it was “Mary”… and then gave him a closer look. “Gene?!”

“Yes!” he said. It was Gene Trapp, and his wife Jo Ellen Ryan was with him along with a few other people. Gene and Jo Ellen doing bird counts and maintain the pollinator garden at the West Davis Pond site in Davis. (They have a house within walking distance of the park.) I’d first met them when I worked at Tuleyome. Gene always supported my desire to be a naturalist, and attended the lectures I gave on plant galls. It was so nice to see them!

They walked me over to where their small birding group was and introduced the leader (who was hauling around a birding scope) as Jeri Langham. Jeri literally walks the trail almost every day. He’s the one who’s set up and monitors all the bird boxes there.

Jeri let us know that the little Western Screech Owl I’d seen regularly in one of the nest boxes had actually had two babies in there this year! Neither the mom nor the babies was outlooking around this morning, but it was fun to think of them hunkered down all safe in their little box-home.

He also pointed out another box in which, he said, had been occupied by Barn Owls. They laid eggs in the box over several days, but on one day, while they were away from the box, a Merganser had flown in and laid several eggs of her own in there.  Brood parasitism (egg-dumping) occurs frequently for these ducks. When the owls found the duck eggs, however, they abandoned the nest… Sad-face emoji.

I gave him my card, and asked him to contact me next time he was putting a group together.  After meeting everyone, and giving Gene and Jo Ellen a hug — which I wouldn’t have been able to do last year — I excused myself to continue my walk.

Along the river, we could see a mama Common Merganser duck teaching her red-headed babies how to dive and scan for fish in the water. Later, Jo Ellen got a photo of them resting and drying off.  The merganser babies are sooooo cute!

I also saw a Great Blue Heron on the shore trying to figure out how to tackle and eat a fish that was nearly as big as it was. I think it might have stolen the fish from a stringer owned by the fishermen further up the shore. I don’t think it was an older cast-off because it hadn’t attracted any vultures, and it looked too large for someone to have just thrown away. I watched the bird struggle with it for several minutes before it gave up.

Great Blue Heron, Ardea herodias, with a fish it couldn’t figure out how to eat.

In the shallows by the river’s edge, I came across several killdeer.  I watched out for their nests (which they create in the stones) but didn’t see any; no babies either.

In the insect realm I found Boxelder Bugs, a Black Dancer Caddisfly, honeybees, a few jumping spiders (one hauling a fly that was as big as he was), and a colorful Case-Bearing Leaf Beetle, among others.  In the shallow water, scooting and hopping through the mud and silt, I found several Big-Eyed Toad Bugs.  Seriously. That’s what they’re called. They have big bulging eyes and a heavy “collar”, and they hop all over the place when disturbed. Never noticed them before.

The find of the day for me, though, was seeing and getting some close-up shots of caddisfly larvae. I was almost done with my walk when I found them, so I wasn’t able to spend as much time with them as I’d have liked to. I was tired, and it was it already getting “too warm” for me. I’ll go back some other morning, first thing, when I’m feeling stronger and it’s cooler outside.  Anyway, I picked up a few of the little buggers and took some photos and video snippets of them.

Caddisflies spend their larval stage underwater, then emerge (like dragonflies do) from the water as terrestrial adults. The most common adult Caddisfly was see around here is the Black Dancer Caddisfly, Mystacides sepulchralis. I’m not sure if the larvae I saw were Black Dancers or some other species, but I think they were from the suborder Integripalpia (the “portable case makers”). They protect their soft bodies by covering them with a case made of bits of gravel, sand, tiny sticks… whatever they can find. After the adults emerge, they only live for a week or two, just long enough to find a mate and reproduce.

“…Case-building caddisfly larvae use [their] silk to construct various portable shelters. They protect soft their abdomen from predators, and abrasion from coarse particles drifting in stream. If disturbed, larva can retreat into the case, which is constantly being repaired when damaged, or rebuilt as the larva grows…”

One of them that I picked up had a case made of sand crystals and tiny sticks; so interesting. While I was taking photos of it, the birding group caught up with me and asked what I was doing — so I gave them the 5-minute elevator speech about caddisfly larvae. I showed them some of the larvae walking through the water, and also pointed out the trails they’d left in the silt on nearby rocks. They were all very excited about it and thanked me fore teaching them something new.

I also found a few galls on this trip including the oak apples, and a couple of willow galls: stem galls created by sawflies, and rose gall created by midges. Lots of different things to see today…

I was out for about 3½ hours and headed back home.  This was hike #47 in my #52HikeChallenge.

Looking for a Mandarin, 05-23-21

I got up at 6:00 am this morning, and headed out to the Elk Grove Regional Park because a Mandarin Duck (Aix galericulata) had been spotted there.  I had seen photos of the ducks before, but never saw a live one, in situ as it were. I walked around the whole 7½ acre lake, but didn’t find the duck I was looking for.

The park is easy to get to and sprawls out over 122 acres. It’s pretty but it’s  too “manicured”, too “Stepford” for me. There are gorgeous heritage oaks (including Black Oaks and Interior Live Oaks), Coast Redwoods, Weeping Willows, and others on the grounds that provide a lot of shade, but they’re trimmed up so high you can’t touch the leaves. So, nature is around you, but you can’t really interact with it very much. I’d prefer something more “scruffy” that I can explore, not just stand in  as though it’s a museum.

Those feelings aside…

I did see a lot of Mallards and Mallard hybrids, Wood Ducks, some Muscovy Ducks, Swan Geese and Canada Geese. Some of the Canadas had goslings at various levels of development. And I saw a group of tiny Wood Duck ducklings, that looked like newborns, swimming around in the water with no mama.

Something bad must have happened to her; I didn’t see her anywhere and she wasn’t responding to the ducklings’ cries. If they can find enough to eat, the ducklings can survive without mom, but they have no protection and no extra heat source when the nights get cold, so… the whole group may be goners. (see follow-up below)

Sad sights were seeing the handsome Yellow-Billed Magpies eating out of the trash cans, and going after the carcass of a squirrel on the road. And speaking of the squirrels… Although there are signs in the park telling people not to feed the geese or the squirrels, I saw one group of people blatantly feeding the geese; and the squirrels run right up to you looking for handouts. One came so close I expected it to grab my pant leg and demand breakfast.

An unexpected sighting was a Black Phoebe nest on one of the pilings in the lake. The babies inside were nearly fully fledged, but the parents were still feeding them. I could see four of them crammed into a nest that didn’t seem big enough to hold one.

Between feedings, the chicks rested in the sun, preened, and stretched their wings. I watched them for quite a while; couldn’t seem to get enough of them. Then I continued on to the other side of the lake and headed back to the car.

I was at the park for about 90 minutes and only walked about 0.7 miles, so it didn’t count toward my #52HikeChallenge tally.

Follow-Up on the Ducklings:

I got a message from Christy of the Sacramento Heron and Egret Rescue, who suggested I get in contact with local rescuer Ben Nuckolls. So, I did that, and Ben said he’d have the “duck lady” who’s at the park every day check on the ducklings. If they still look in distress or are unclaimed by a mama duck, they’ll try to coordinate a rescue. Thanks, everyone!
