Trail Stewarding at Effie, 08-06-20

I got up around 5:30 am and headed over to the Effie Yeaw Nature Preserve around 6:00 am.  It was cool, 57°, and overcast again this morning. There was a slight breeze blowing, and the temperature never got over 61° all the while I was out there.  So, it was a really nice walk weather-wise.

I’m starting up my Trail Steward walks again, even though right now, I’m kind of off-schedule, walking on the days when the weather is the most auspicious. Today, I was more “official”, wearing the vest my naturalist students had given to me, along with my name tag. I thought the vest might be “too hot” for me, but with today’s nice morning weather it was comfortable.

Unintentional selfie my cell phone took of me. You can just see the neckline of the vest…

I took a route down the Meadow Trail to the River Trail and then back up to the Main Trail. I was hoping to catch a glimpse of the coyote family that’s supposed to be out there now, but no such luck. Did find a lot of scat, though.

I also saw several deer today, though. Mostly, young bucks who were full grown but not old enough to have their first antlers yet. One of them walked right down to the edge of the trail in front of me, maybe 5 feet away… I also saw one doe with an older fawn.  No other babies, though, which is a little surprising.  They should be out and about by now. I wonder if there just weren’t too many born this year.

Besides looking for the baby coyotes, I was also looking for Kernel Flower Galls on the live oak trees.  This is the season for them, but I hadn’t seen any yet.  Because the galls form on the underside of the oak leaves, you have to turn over a lot of leaves to find one…or two or three.  I think I checked out about 6 trees before I found any, but find them I did.  Yay! I also found some really nice-looking Crystalline galls. 

On the “Frankenstein tree” (half Blue oak, half Valley Oak), which hasn’t sported any galls at all in the past few years (because, I suspect, Round-Up or some other herbicide was sprayed around it) there were some Saucer galls now.  Something is better than nothing, in my mind. And lots of the live oaks are now sporting the spiky Live Oak Gall Wasp, 1st Generation galls. I don’t know why that makes me so happy, but it does.

I caught sight of a couple of Nuttall’s Woodpeckers today, and one of them looked incredibly “ratty”, like it just got out of bed and hadn’t combed its feathers yet. I’m assuming it was either a juvenile just getting its adult feather in, or was an adult going through a major molt.

Because the black walnuts are starting to ripen, the squirrels can be heard munching on them in the trees. The scritch-scritch-scritch of their teeth against the nuts as they try to scrape the husk off is a dead giveaway of their location and what they’re doing. 

A lot of the squirrels’ muzzles are darkened by the juglone in the walnut hulls, so they look “dirty”, like little kids who’ve just eaten mud pies.  So funny looking.

Eastern Fox Squirrel, Sciurus niger. It face is stained from black walnuts.

According to the Iowa State University: “…We now know that juglone is produced in the fruit, leaves and branches, and can be excreted from the root system into the soil. The actual concentration in each tree part varies with the season. In spring, juglone is concentrated in the actively growing leaves. The amount of juglone in the roots remains relatively high throughout the summer, and the concentration of juglone in the hulls of the fruit increases as the crop matures. All species of the walnut family (Juglandaceae) produce juglone. This would include many native trees such as black walnut, butternut, the hickories and pecan. However, black walnuts have the highest concentration of juglone…”

You can make a natural dye out of the walnut husks, but be careful. The stuff can dye your skin as well.

It was nice to see that the bees are still inhabiting the “bee tree” along the trail. I always worry that someone will try to evict them. Today, I watched one of the Fox Squirrels run right up to the tree, and then did a careful zig-zag motion to get away from the bee-laden mouth of the hive. Do squirrels like honey?  They’ll eat just about anything…

The feral hive of Western Honeybees, Apis mellifera, in the “bee tree”.

Along the trail, too, I found a cast-off stick from one of the nearby trees that had about six or seven different species of lichen on it! Because the air was cooler overnight, there was a little bit of condensation on the ground, so the lichen got just wet enough to wake up a little bit and look colorful. So much life crammed into one little space.  It always amazes me.

As I was walking toward the end of the Bluff Trail, I met another volunteer named Margaret. She said she had been a volunteer at EY since 2004, but was just starting the trail walking gig. When I introduced myself, her eyes lit up. “Mary Hanson? Oh, I just LOVE your beautiful photos and posts!” Awww. A fan! Kind of made my day. Hah!

I walked for about 3½ hours and then headed home.

As an Aside: Dispose of Used Masks Properly!

Discarded masks are potential carriers of disease and pose a real danger to animals and the volunteers tasked with cleaning up the trails. Used masks and gloves, which cannot be recycled, pose a problem for the environment. READ MORE HERE.

And More Galls at the Cosumnes Preserve, 08-03-20

I got up around 5:30 this morning, and headed out the door with my friend Roxanne to check out the Cosumnes River Preserve.  It was 64° when we got there – already almost too hot to start a walk – and got up to 99° by the late afternoon. 

On our way to the preserve, we spotted a couple Red-Tailed Hawks and what we believe was a Swainson’s Hawk, and also saw a coyote loping across a field. When we got to Twin Cities Road, we took the route around Bruceville and Desmond Roads to see if we could spot anything in the fields around there.

Not a whole lot is happening out there right now because the cattle weren’t using the land, and there’s no water for the bird for the most part.  We did see a rather large covey of California Quails, several males and females all scurrying around. They’re such adorable chubby birds.

 We also saw an adult cottontail rabbit and a tiny baby one (on the other side of the road).  Along with them we saw some blackbirds, Mockingbirds, and a handful of sparrows and finches in the blackberries bushes but that was about it.  Still no concentrations of insects, and next to nothing when it came to dragonflies.  Along Desmond Road we did find a few Buckeye butterflies and some blue damselflies, but not as many as there should be during this time of year.

While we were going down the stretch of Desmond Road we saw a pair of White-Tailed Kites, but the birds wouldn’t sit long enough in the treetops for us to get any photos of them.  Of course, most of the wetland areas and even the fields were dry, dry, dry.  There was only one part of the wetlands that had water in it, and we saw about a dozen Great Egrets in there along with a few ibis, some Killdeer, and a couple of Greater Yellowlegs.  Not a lot, but at least it was something.

Great Egrets, Ardea alba

There are quite a few Valley Oaks along one side of Desmond Road, though, so we parked the car and checked them out for galls.  Oddly enough, we’d never actually looked at them before (except for as perches for the birds in the area).  We were able to find specimens of quite a few different galls including some fuzzy Club Galls, along with some Western Spotted Orb-Weaver Spiders and a handful of Paper Wasps.  I’ll have to go back there in a few weeks and see if anything new crops up.

Gall of the Club Gall Wasp, Atrusca clavuloides

The gate to the boardwalk area was open, so when we got there Rox parked in the small parking lot there instead of on the street.  The slough and pond right by that entrance was nearly bone-dry and there were dead carp lying around stinking up the place. It’s just sad to see that.  Seems cruel to drain off the water and let the fish suffocate to death. [Sad-face emoji]

The carcasses of dead carp were lying in the nearly-emptied pond.

Rox and I walked to the outer edge of the pond where there are trees lined up near the road, and checked them out for galls as well.  It’s mostly Valley Oaks and White Ash trees along there, and we were able to find more wasp galls, including the “Woollybears”, and some really good specimens of ash leaf-curl (caused by aphids) and ash “flower galls” (caused by mites). 

Galls of the Woollybear Gall Wasp, Atrusca trimaculosa

Rox also got an incredible photo of a honeybee snacking on the drippings of a row of Flat-Topped Honeydew galls. Her photo is on the left below. The other two photos are by me.

I know I’ve told you this before, but it bears repeating when talking about gall wasps and the strategies their larvae use to defend themselves.  Some have thick skins of their galls, some of their galls have spines and prickly things, some pull tannins from the leaves which acts as a sort of insect repellent to keep predator insect species away from them while the larvae grow and develop inside their galls.  But the honeydew gall-wasps have a very interesting strategy.

They “pay” other insects to act as bodyguards for them.  Inside their gall, the larvae generate honeydew which is then exuded through the porous surface of the gall.  The honeydew attracts “aggressor species” like ants and Yellowjackets, who defend the cache of honeydew for themselves by driving off other insects.  The ants and Yellowjackets get the sugar that’s hard to find elsewhere in the summer months, and the gall-wasp larvae get protection.  I just think that’s so cool…

* Warning * Rant * Warning * Rant *

While we were gall hunting and taking photos, a gentleman came up to us to let us know that he was leaving and closing the gate behind him, but he wouldn’t lock it.  When we were done, we could open the gate to retrieve the car, but then needed to close the gate again when we left…so, we did that.  Apparently, we had unwittingly picked a date when the area around the boardwalk was closed because they were spraying Round-Up. 

Seriously?!  Round-Up?! I thought this was supposed to be a PRESERVE?

Science has proven that the stuff gives humans cancer and damages the environment.  “…Evidence is growing that glyphosate, the active ingredient of Roundup, [impacts] the metabolism, growth and reproduction of aquatic creatures and could be altering the essential gut bacteria of animals such as bees… The soil half-life of glyphosate is approximately 47 days (with a range of 2 to nearly 200 days depending on soil type and various environmental conditions)… Shifts in microbial community composition in soil, plants and animal guts resulted. Glyphosate may serve as one of the drivers for antibiotic resistance…” 

[[I also personally believe that Roundup also destroys the layer of mycelium under the surface of the soil, and some studies seem to support that contention.  It, like the neo-nics, is just plain BAD NEWS for the planet.]]

The Cosumnes preserve is a water-based river-front and wetland area.  And they’re dumping Roundup into it.  Unbelievable!  Who knows how much of that crap we were exposed to while we were there.

Okay, the Rant is Over Now. Continue Reading…

Rox and I left that area and went down the road next to the nature center.  There’s a long boat ramp there that cuts alongside an oak grove and field, and ends at the river.  We checked out the oak trees and looked for milkweed plants, and after some time there I just couldn’t walk anymore.  It was already 78°, too hot for me, so I sat on a bench in the shade while Rox went down to the water’s edge.  When she came back, she said there wasn’t a lot to see there – no dragonflies, no birds to speak of, but there was some invasive water hyacinth in the water.  We’d seen a LOT of that in drainage ditches along the highway.  She said there wasn’t a lot in the water by the boat launch – yet.  Give it a week; it’ll be covering everything. 

Photos I took of the water hyacinth in the Cosumnes River a few years ago.

Water hyacinth is a gorgeous plant that floats on the top of the water on its own air-filled bladder; its flowers are just beautiful.  But it’s totally invasive. It’s scientific name is Eichhornia crassipes, so a lot of people call it the “crappiest plant”. It was introduced to the US in the 1880’s as an ornamental water plant (for rich people’s gardens),but escaped as is now considered an invasive everywhere.  It got into California around 1904.  It can sprout from rhizomes (growing in the mud under the water) or from seed.  The seeds are sticky and cling to the feet and feather of waterbirds which then transport them to wherever the bird goes.  The plants grow really fast and can completely cover an clog ponds and waterways in just a matter of weeks. 

As it covers the water, it reduced the places where waterfowl can land, rest and feed, it blocks off sunlight so the water “dies” along with everything in it (oxygen levels drop, CO2 levels rise), and it also transpires a lot of water into the air (some calculations say it’s 8 times faster than normal evaporation)… so the water level in covered patches actually drops. Because the floating mats of the water hyacinth are so broad and dense, they force out native plants that wildlife needs for foraging purposes.  Most animals can’t eat the hyacinth because of its high tannin levels (and because the plants are about 95% water – so have no nutritional value. (So biodiversity plummets.) Standing water caught in and between the matted leaves of the plants become breeding pools for mosquitoes.  And when the hyacinth dies, it poisons the water so nothing can drink it.  Yikes!

How do you control the stuff?  Well, once it’s introduced there isn’t a lot you can do except rip it out, but you have to get every fragment of the plant and dredge up the rhizomes, which can be really labor-intensive and very expensive. You can’t use herbicides on it because the herbicides will poison the water the plants live in. Some places have tried using floating barriers to keep it contained, but that doesn’t stop the spread of the seeds… So, it’s tough.

            With so many “bad” attributes, Rox and I wondered if it had any useful properties at all.  There’s a report by United Diversity that says there are several different places trying to figure out what to do with the stuff.  It’s plant material, of course, and has fiber content, so most of the processes being tried are in the manufacture of paper, fiberboard, yarn, rope (basket-making) and charcoal briquettes. On a larger scale, it’s being tested out as a source of biomass fuel, and in some places is being tested as a first-step in water treatment (from sewage to fresh water).  Here is a PDF of that report.

When we were heading back home, I apologized to Rox for being such a “heat wuss” and cutting the walk short. But she pointed at the clock on the dashboard and said, “We’ve been out for four hours. We did our regular morning…”   I hadn’t realized I’d been walking for that long; no wonder I was tired!

Checking out the “Reverend Mother” tree, 07-31-20

I got up around 5:30 this morning and after giving Esteban his breakfast and letting him out for potty, I headed over to the William B. Pond Park along the American River to do a kind of recon on the galls there.

There are several oak trees on the manicured lawn that often provide an abundance of specimens, and then, of course, there’s what I call the “Reverend Mother” tree: a particular Valley Oak that I go to every year.  It sits at an intersection of different parts of the trail near the river, and sports a wide variety of galls throughout the late summer.  I wanted to see what was out there before I brought my friend Roxanne over there on a gall hunt; to make sure that there was something there to see.

The galls are still just starting to emerge, but I did see several different species, including a beautiful Rosette gall (on the Reverend Mother tree). 

Rosette Oak Gall Wasp, Andricus wiltzae

There were also a couple of oak apple galls that were oozing black goo.  I cut one open and found the wasp larva inside, but couldn’t see any indication of other insect that was causing the rot. So, I figured they had some kind of fungal infection.  I couldn’t find any information on that in my research yet, though, so I’m not sure.

The honeydew galls aren’t big enough or engorged enough to start dripping, but I did see some Yellow Jackets hanging around the tree, looking for them.

CLICK HERE for the full album pf photos.

While I was checking out some Round Galls, I saw a tiny red nymph, shaped kind of like a cigar, with black coloring at both ends.  I was surprised that it was relatively easy to figure out it was the nymph of some kind of Tube-Tailed Trip.  (Thank you, BugGuide.net)  But I’m still not seeing the number of insects I’d expect to find in the summer by the water.  I only saw one damselfly, some kind of Dancer.

Oddly enough, I didn’t see or hear many birds along the river, either, but I did come across some California Quail and a Bewick’s Wren. 

I walked for about 3 hours and then headed back home.

Seeing with a naturalist’s eye: so much life among the leaves.

And the Galls are Showing Up at the EYNC, 07-29-20

Up at 5:30 this morning and out the door by 6:00 am to go with my friend and fellow naturalist Roxanne to the Effie Yeaw Nature Center. I’m starting my Trail Walker duties there again after several months off.  I still need a neon orange reflective vest to wear (it was due today) to look more “official”, and I’ll wear that next time.  I can also wear the khaki vest my naturalist students bought for me, but it’s heavier material and I think it’ll be too warm to wear in the summer months.  So, today, I was just in shirt-sleeves – no vest. 

It was about 61° when we got there, and warmed up quickly. The high today was around 100°.

Rox and I were most focused on finding galls, and checked out some of the Valley oaks, Blue oaks and Live Oak trees scattered around the preserve. It’s still a little bit early in the season, but we saw quite a few different species.  On the Blue oaks, we found some small specimens of Crystalline galls, Plate galls, Saucer galls, and Urchin galls.  On the Valley Oaks we found Red Cones, Fimbriate galls, a Yellow Wig, and Spiny Turbans. 

And I was really happy to find lots of the spiny first-generation galls of the wasp Callirhytis quercuspomiformis.  I hadn’t seen them there yet (since the trees were trimmed), and was so happy that they had re-established themselves.  When they’re new and bright green, they feel spongy, but as the galls age, they firm up and turn tannish-brown.

We saw a few deer, including a pair of bucks in their velvet: a four-pointer and a three-pointer. (The eye guards don’t count.)  When their antlers are growing, they’re very sensitive to touch, so there was no head-butting… just a deep long stare from the older buck telling the younger one to back off.

Here’s an article I wrote about the deer and their antlers in July of last year.

We also saw a couple of females, one near the nature center and one out by the river. They were by themselves and we speculated that they were either young does that didn’t have fawns this year.  July is the fawning season at the preserve, but we didn’t see any babies during this trip.

When we were heading out of the preserve after about 3 hours, we came across Rachael,the volunteer coordinator, who was helping to woman the docent table outside of the nature center building with some of the other volunteers.  She told us that earlier that morning, some of the docents had seen “tiny baby” coyote pups along the River Trail at the preserve!  Oooooo, how cool! I’d love to be able to see those little guys. I’ll have to keep an eye out for them the next time I’m out there.

She also said that later this summer, the river front near the preserve will be re-groomed to provide more spawning space for salmon.  Last year similar work was done along the Sailor Bar portion of the river, and this year will be the Effie Yeaw area’s turn.  The refit and reconstruction of salmon-friendly habitat will include dredging and reforming some of the river bed, and laying down tons of gravel that’s of the right size and consistency for the salmons’ “redds” (nests).  If the gravel is too big or too little, the salmon won’t lay their eggs on it.  The work at Sailor Bar was first done in 2009 and during that year about 1000 redds were spotted in the area.  Last year, there were ZERO because the majority of the finer gravel had washed away.

It’ll be interesting to watch the work progress in the river near the Effie Yeaw Nature Center/Preserve, and fun to see if lots of salmon can be spotted from the shore in the fall and winter months.

A parting view. As we left, we saw several Rio Grande Wild Turkeys, Meleagris gallopavo intermedia, stopping to take a drink from the pond.

Two Spots in Woodland, 07-26-20

Up at 5:30 am and out the door with my friend Roxanne to head out to the city of Woodland by 6:00 am. It was about 61° already that early in the day, and it got up to 100° by the late afternoon.

We wanted to visit the East Regional Pond and Ibis Rookery in Woodland.  Both of them are just off Road 102, and pretty close to one another.  We’d let Greg Ira (the statewide director for the University of California’s Certified California Naturalist program) know we were coming, so he met us at the East Regional Pond after we stopped at Dutch Brothers for some much-needed coffee.  I’d never been to the pond before, so it was a fun first for me. 

The pond is a large water retention pond right across the street from the turn out to Farmer’s Central Road in the city of Woodland, CA. It’s surrounded on three sides by private property and protected nature areas. Because these areas are screened off by fences, you cannot walk all the way around the pond. There is a wide gravel trail, however, and three viewing platforms from which you can view and photograph wildlife. 

This time of year, there isn’t a lot of water in the pond, but I could definitely see the potential for future outings in the winter and spring when the rains come and the weather cools off. I really enjoyed being able to see the place.

We got to see Showy Egrets, Great Egrets, American Avocets, Black-Necked Stilts, Greater Yellowlegs, Spotted Sandpipers, White-Faced Ibises, pelicans and other birds.  Many of them were in the far side of the pond, but as we walked from one viewing platform to another a handful of them sort of followed us around. 

There were little cottontail rabbits bounding all over the place.  Sometimes we’d see two or three together, running this way and that, chasing each other, stopping to munch a little bit on the vegetation. They were constant conversation interrupters.

Desert Cottontail Rabbits, Sylvilagus audubonii

We also saw about four or five Pacific Pond Turtles in the shallows of one part of the pond. They were all poking their heads up above the surface.  And when they moved around, they left a trail of mud floating behind them in the water.

Although there were gnats and midges in the air, we didn’t encounter many insects, and saw only one or two dragonflies. But we did find a large Paper Wasp nest. These wasps are usually pretty mellow, so I was able to tilt the nest up to get some better photos of it.

Paper Wasp, European Paper Wasp, Polistes dominula

The queen builds all the first cells and rears all the first offspring by herself. After that, her daughters do all the work, and she just lays the eggs. In this nest, we could see that the larvae were developing in their cells at different stages, and that some of the cells had already been sealed off. Inside the sealed cells, the larvae pupate, and then emerge as adult wasps. Here is an article I wrote about them in 2017.

After about an hour or so, we headed over to the ibis rookery.  I was assuming there would be a lot of juveniles out there by now, and I was right. There were a handful of the ibises still sitting on eggs, but most of the nests had trilling, begging, head-bobbing youngsters in them.  With their striped bills, they’re very striking.            

We also saw some Coots paddling through the water with their own youngsters behind and around them.  I hope they won’t hate me for saying it, but I think their babies are the goofiest, funniest, ugliest little things I’ve ever seen.  “Ugly Baby Judges You.”  They’re partially bald with red faces and yellow pokey-out feathers are called “ornaments”. The more ornaments a baby has, the more attention and food she’ll get from the parents.  Bling matters, apparently. Here’s an article I wrote about them in 2018.

Back to Mather Lake, 07-24-20

Up at 5:00 am again, to head out to Mather Lake Regional Park at 6:00 with Roxanne. We wanted to check out the side of the lake opposite of where we were earlier in the week.  [[For some reason, my hair is doing this humorous pokey-out thing on one side of my head, so the left side looks “startled” and the right side looks “bored”. Hah!  I must have slept on it weird.]]

Not a ton of bird sightings today; mostly just the usual suspects.  We did catch a glimpse of some Belted Kingfishers when we first arrived, but they’re shy and moving very quickly, so getting a photo of one of them is really difficult.  We could HEAR they chattering on both sides of the lake, but couldn’t get into a position to see them clearly. 

A very bad photo of a Belted Kingfisher

There was one young Canada Goose fledgling that we spotted “doing yoga”, standing on one leg, on the lawn area.  It wasn’t until it moved that we realized it was missing a foot.  Everything below the knee was gone on one leg, so when the bird walked it had a very bad very distinct limp.  I presumed that it may have gotten its leg tangled in fishing line which eventually amputated the bottom part of the leg, but there’s no way to be sure.  It must have had that injury happen very early, when it was still a gosling, because the stumpy leg seemed totally healed, and the bird had seemingly adapted well to its “defect”.

Crippled Canada Goose fledgling

We were surprised to see a hawk flying around where we were looking at galls.  It was being harassed by small birds, and took sanctuary among the leaves of the trees, but always kept itself just out of sight, so we never got a really clear view of it.  By the mottling on the chest, I assumed it was a young bird, maybe a juvenile Cooper’s Hawk or Merlin, but the head just didn’t look right. I loaded the sighting into iNaturalist, and it came up as possibly a Sharp-Shined Hawk, but I’m not sure.  Let’s see if anyone can give me a better ID.

Cooper’s or Sharp-Shinned?

We saw quite a few galls on the oak trees (and willow trees), but most of them are still in their early development stages so they’re not very large yet.  In another two weeks or so, they should be out and looking quite beautiful.  I think we saw about 20 different species, which was great. 

Among them, we saw some unusually huge examples of the round, spiny first generation Live Oak Gall Wasp galls. I was happy to see them because I hadn’t seen ANY yet this year and was worried they weren’t going to make it out. These first generation galls contain a dozen or more parthenogenetic female larvae that reproduce asexually.  (The second generation has it’s own special gall and contains both male and female larvae that reproduce sexually.)

Live Oak Gall Wasp, 1st Generation, Callirhytis quercuspomiformis. This specimen was huge and could have contained 20 or more larvae.

On the Live Oak trees there seemed to be a LOT of acorns this year.  We also found one example of “drippy nut”, an acorn that was oozing clear sticky discharged caused by a bacteria called Brenneria quercina.  It gets into the acorn when the acorn is pieced by the ovipositor of a wasp or otherwise breached (by some other bug or a bird pecking into it).  The exudation is super-sticky. I got a little of it on my thumb and it took almost an hour to work it off of my skin.

Drippy Nut, Brenneria quercina, AKA Lonsdalea quercina [a bacterium that infects wounds in oak tissue/acorns]

As we were leaving, we spotted some juvenile California Ground Squirrels.  Some were playing, and one was digging in the dirt. As we watched the one that was digging, we saw it lift a large flat rock with its mouth and moved it out of the way so it could get at whatever underneath it.  I got a video snippet of that one.
