Lots of Fledglings and Other Critters Today, 06-30-19

I got up around 5:30 this morning and immediately headed out to the Effie Yeaw Nature Preserve for my weekly volunteer trail walking thing.  It was cool, around 55°, when I got there, but as soon as the sun got up a little higher in the sky it started to heat up.  It ended up around 75° by the time I left the preserve.  There were some latent clouds overhead which meant it was humid, too. Not my favorite.

Along with the usual suspects – deer, Acorn Woodpeckers and Wild Turkeys – I got to see quite a few fledgling birds out today.  The fledglings are fully feathered and the same size as the adults, but not quite adept at flying yet, so they spend a lot of time around ground level begging their parents to feed them.  They’re so bossy!  I watched one little House Wren fledgling sitting on top of a pile of old tree limbs.  For a while, he tried posturing like the adults do with his little tail standing straight up behind him, but then he got tired and just sat and dozed… until he saw or heard one of his parents flying by. Then he’d perk up and open his mouth wide expecting food to be dropped into it. Hah!  Although I could see the parents flitting around where he was, they also had other fledglings in the nearby shrubbery (which I could hear buzzing away), and because I was standing between the shrubs and the baby on the woodpile, they wouldn’t go near him. After getting quite a few photos of the little guy, I decided I’d better move on or he wouldn’t get fed at all.

I also came across two fledgling California Towhees.  Now, the California Towhees usually look kind of obese and drab to me, but the babies… they were soooo scrabbly looking; total bed-heads!  They were sitting close to one another with their feathers all fluffed out, so they looked extra fat and messy. Made me chuckle.  One was content to sit and wait for their parents to bring breakfast, but the other one was extra hungry, I guess, and kept tugging at the dead grass near them trying to get something out of it. Can’t get milk out of a stick, son. Sorry.

Further on along the trail I could hear a parent and fledgling Red-Shouldered Hawk calling to one another.  The fledgling was very loud and persistent, demanding to be fed, and the parent would call back him as if to say, “Shut up! I’m working on it!”  I eventually came across the fledgling sitting up in the bare branches of a tree. (He was so loud he was announcing to everyone exactly where he was.)  He saw me and tried to scramble away to other branches but was still unsure of how to make his wings work, so he looked pretty clumsy.  He stuck to the shadows as much as he could then, but I was still able to get a few photos of him.  (And I’m assuming he was a male based on his coloring; females are usually larger and have less vivid colors.) 

I also found one of the parents, sitting quietly now in the low branches of another tree right along the side of the trail, just above eye-level, ignoring the fledgling. Totally habituated to people, it didn’t move from its perch, but kept its eye on me as a passed by and stopped to take some photos. I think they’re such handsome birds.

Among the other things I found today were a few Pumpkin Galls on the leaves of a Live Oak tree. It’s kind of early in the season for those, so I was surprised to see them.  They’re super-tiny galls, and if you don’t know where or how they develop you’d completely miss them. Right now, they’re pale green, but come fall they’ll turn dark orange and fall off the leaves onto the ground were the little larvae will pupate through the winter.

I found a few Eastern Fox Squirrels and some California Ground Squirrels.  I was surprised to see one of the Fox Squirrels climbing through poison oak and eating the berries! Yikes!  I mean, I knew that the toxin in poison oak don’t generally harm wildlife, but I’d never actually seen any of the animals eating the stuff before.  I also saw a Fox Squirrel eating the husk off of a black walnut and watched a Ground Squirrel eating the tops off of some other plants.  (I think that gal was blind on one side, but once she saw me she moved too fact for me to get photos of her blind side.)

The other cool thing I spotted along the trail was that feral honeybees have found the tree along the Pond Trail again and seem to be setting up house there.  I saw them last year (I think it was) checking out the big opening in the side of the tree, but they left the site after a few weeks.  I guess the queen didn’t like it.  Now the opening is more covered with plants, so maybe it will feel more “protected” to them and they’ll stay there this time.  I let the gals in the nature center know they were there, so hopefully they can discourage hikers from walking off the trail to see the bees. We’ll see.

Only the Vulture Seemed Cooperative, 06-27-19

I got up around 5:00 am, let the dog out to go potty and fed him his breakfast. Then I headed over to the Effie Yeaw Nature Preserve for a walk.  I was joined by fellow volunteer trail walker, Mary Messenger (“The Other Mary”).  The weather today was beautiful, cool, breezy, sunny… in the 70’s. Just gorgeous.  I was able to keep the bedroom window open for most of the day to let the fresh air in.

At the preserve today the sightings were few and far between, and Nature was playing keep-away (we’d see something, but it was gone before we could get any decent photos of it). It took quite a while before we spotted a single deer, and I’m hoping that’s because a lot of the does are off having their babies right now.  Among the deer, I did see a couple of bucks in their velvet, including the one with the wonky antlers (long on one side, stunted on the other). 

And I came across a male Wild Turkey that I assumed was sick. It was hunkered down on the ground and breathing in short breaths, as though it might have been in pain.  It let me get to within touching distance of it and made no effort to get up or get moving.  My brain goes to the two most pervasive threats to the turkeys: rat poison and West Nile virus.  The turkeys in the preserve are surrounded by a huge residential area… and those nasty poison-pellets folks put out for rats look like food to the birds.  And we’re in the middle of the mosquito season, so West Nile can be a factor for many animals.  There’s no way to know what was affecting this papa, though, unless he can be caught and examined.

I took a photo of the turkey with some of the landscape markers so it would be easier to locate him at a later date/time if necessary.

According to the National Wild Turkey Federation, other things can also impact on Wild Turkeys, such as avian pox (which can result in the lesions in the esophagus and make breathing difficult for the birds) and several different kinds of equine encephalitis. (Usually, though, the birds are carriers of the equine diseases and don’t succumb to them themselves.)  Avian influenza and Mycoplasmosis can also be problematic, but they usually only affect domestic turkeys kept in small confined areas where they’re breathing each other’s crap for days on end. Poor babies. 

On a happier note, we did come across a very cooperative Turkey Vulture who was preening himself on the end of a large barren branch in a tree… and on that same branch was an Eastern Fox Squirrel preening, too.  So, we got quite a few photos of both of them.

The Other Mary had to cut her walk short because she had a lunch date with an old friend, but I kept walking for another hour or so after she left, so I put in about 4 hours of walking before heading home again.

The 1st Summer 2019 Naturalist Field Trip, 06-15-19

I got up at 4:00 this morning, got the dog fed and outside to pee, and then headed out to Woodland for our first field trip for the summer naturalist class.  I got to the Woodland Library around 5:45 am and waited for my coworker Bill and the students arrive. The weather was VERY cooperative today. I was worried that the summer heat would make our field trips unbearable in the summer, but today it was nice.  It was in the low 60’s when we headed out, and only about 78° when we came back, so that was great.  There was also a slight breeze which helped, too.

When everyone got to the library and had signed in, we all headed out to the Sacramento National Wildlife Refuge.  I left my car in the parking lot and went with Bill in his van along with our student, Jeanette, who is a middle school teacher.

  • Locate and identify at least fifteen (15) animal species (birds, amphibians, reptiles)
  • Locate and identify at least ten (10) plant species
  • Locate and identify at least ten (10) insect species

While we were walking around the nature center, I think they all got the majority of those requirements!  The insects were probably the most difficult for everyone, but we’ll see on Friday (at class) how well everyone did. 

Near the nature center, we came across a large fat weevil sitting on the top of the flowering head of a tule.  Bill rapped on the weevil a couple of times and figured it was dead, but when I stroked it, its feet moved, so we all inferred that the weevil was in a state of torpor, waiting for the sun to get a little higher in the sky so it could warm up more and start moving around. 

Everyone took photos of it and tried to identify it using the iNaturalist app we’d told them about in class on Friday.  It came up as a Billbug Weevil from the genus Sphenophorus. If you look at the map in iNaturalist, though, you’ll see that Billbug Weevils have been sighted all over the globe. So, calling this a Billbug Weevil is somewhat accurate, but for a more precise ID, I wanted the students to try get down to the species level on the weevil when they got home. Insects can be especially hard to ID because there are literally millions of them, and you have to deal with taxon levels that include superfamilies, tribes and subtribes before you can get close to the species. It will be interesting to see how far the students are able to get.

We also found a buckwheat plant that I didn’t recognize as buckwheat at all because its shape wasn’t like any buckwheat plant I’d seen before.  The signage by the plant said it was California Buckwheat, Eriogonum fasciculatum, as did iNaturalist, but that didn’t quite look right to me. The leaves were the wrong shape.  So, I did a little more research, and I believe it was actually St. Catherine’s Lace, Eriogonum giganteum, a kind of wild buckwheat that usually only grows in Southern California. When we were studying the plant, two of the students (Jeanette and Edna) also observed that some of the flowers still had their pink pollen balls and others did not… and we inferred that those that didn’t have their pollen balls anymore had already been pollinated.

When it came time to drive the auto-tour route, I drove Bill’s van so he could do more observations, and Jeanette and another student, Mica, a retired farmer, came along with us. Bill was able to open up both sides of his van, so the gals could get an unobstructed view of what was out on the preserve. Although everyone was able to go at their own pace along the route, we stopped at two of the park-and-stretch areas so we could compare notes and get a closer look at things.  At the first stop, the students Ken and Alison, who are already expert birders, were helping the students spot and identify bird species and also explained what they meant when they talked about the birds’ GISS.

GISS stands for “General Impression, Shape, and Size” (originally a military term). Birders often use the bird’s GISS as a way to do a preliminary or in-field identification of a bird when it’s backlit (only seen in silhouette) or is too far away to see any details of its coloring. So, Alison and Kent were able to distinguish a pair of Northern Harriers flying over our heads from the Red-Tailed Hawk that was flying near them by nothing but their GISS. Very cool.  I’m nowhere near being that kind of an expert. 

At the second park-and-stretch spot, students relaxed with their lunches for a little while, and I was able to find a couple of examples of a specific kind of gall to tell them about, a Cottonwood Petiole Gall and is created by the aphid, Pemphigus populitransversus. The wingless female aphid called a “stem mother” chews at the leaf petiole (the stalk that joins a leaf to a stem) until it swells and then she climbs inside the swelling and has her babies inside of it. The baby aphids are born live and can be in either a winged form (called an “alate”) or without wings.

Pemphigus populitransversus

While the students were resting and checking up on their notes, one of them, Alison, let us see what she’d put into her field journal for the morning. She’s an artist, and she uses fountain pens and watercolors to write and decorate her entries. It was beautiful. I can hardly wait for Friday when all the students share their journals, so I can take photos and let you see what they’re doing…

I also overheard a couple of students talking about how much they enjoyed the class, how much they’ve learned already (in just two sessions) and how many resources we’ve introduced them to that they didn’t even know existed before now.  That is so gratifying!

One more learning moment: On the eucalyptus trees along the end auto-tour route on Saturday, I also stopped to pull a leaf off of an obliging eucalyptus tree, so I could show the students in our vehicle the white teepee-like formation on it that some folks mistake for galls.  The formations are actually called “lerps” and they’re created by a tiny insect called the Red Gum Lerp Psyllid, Glycaspis brimblecombei. These insects spin little white houses for themselves made of sugars and wax pulled from the leaves. They’re often very sticky with the honeydew produced by the insects.             

When we were done with the tour, everyone went their separate ways.

A Lot of Little Moments, 05-14-19

I got up at 5:00 this morning and took my time getting ready to head out to the Effie Yeaw Nature Preserve for my trail-walking thing there. It was cool for most of the day – a rainstorm is supposed to move in tomorrow – so it was perfect walking weather. I was joined by fellow volunteer Mary Messenger – the Other Mary.

We saw the usual suspects like deer, House Wrens, and suchlike. One humorous encounter was with a European Staring who had its adult feathers in but was acting like a brat. It was sitting in a tree just opposite where I had seen the fledglings poking their heads out of the nesting cavity last week. It was making a lot of very loud squawks and peeps, and flapping its wings trying to get attention. Might have also been a female looking for a mate to come feed her. Whichever.  She was so loud and so animated; you couldn’t miss her.

Another funny moment was walking in on a pair of Fox Squirrels who I think were making out.  Hah! Get a room, you guys!

CLICK HERE for the album of photos.

I saw another Starling in another part of the preserve that was taking twigs OUT of her nesting cavity, which I thought was weird.  And we saw a male Mourning Dove picking up bits of grass and carrying them to his mate in a tree off the trail.  A House Wren was carrying food to his babies… Everyone was moving stuff around.

I also saw a pair of Wood Ducks. They flew into a tree overhead, and then the female flew to an adjacent tree and “disappeared”. She flew out to the first tree next to the male, then flew back to the other tree and disappeared again. I tried to see where she was hiding out and assumed she might have had a nest in a cavity in the tree, but I just couldn’t see her. Then she flew out one more time, and this time she had something orange and fuzzy in her bill. She flew off with it, and the male followed her. I couldn’t tell what it was, really, and wasn’t able to get any photos of it, but I think she was retrieving a duckling that was refusing to come down from the nest! I’d never seen or heard of anything like that; it was kind of amazing.

And we caught a glimpse of a young coyote. He came out onto the trail in front of us with a short growl and then ran off into the high grass where we lost sight of him. He was pretty small, probably a teenager. After we saw him, we kept an eye out for mom and dad; they usually travel in a pack when the pups are young.

We walked for about 4 hours, which is pretty much the limit for both of us, and I headed back home.

At the Sacramento and Colusa Wildlife Refuges, 05-06-19

Certified California Naturalist, Roxanne Moger and I went out to the Sacramento National Wildlife Refuge around 6:00 am this morning. The weather was beautiful today, but there wasn’t a lot to see at the preserve. We’re kind of in between seasons, so the large flocks of birds have all left, but the insects (like dragonflies, damselflies, and orb-weaver spiders) haven’t arrived yet. We did see swarms of Painted Lady butterflies and some Cabbage White, but none of the other species normally seen there in the late spring/early summer.

Roxanne did all the driving, but we stopped a couple of time to get out of the car and walk parts of the trail or explore the boundaries of the park-and-stretch areas. Some of the vernal pools on the site were in bloom: all golden yellow and purple with Goldfields and Downingia. Just beautiful.

Although the species list at the end of the day wasn’t as long or as varied as I’d like, I did like the fact that I saw a few things I’d never seen before and learned more about some species than I’d known before. That’s what really makes these outings fun.

A large fly landed on the passenger side mirror of the car partway through the auto-tour and at first I thought it was a Robber Fly (those guys are pretty big). We were both intrigued by the fly’s huge goggle-like eyes and his tenaciousness.  He held onto that mirror for quite a long time.

When I got home, I looked up the fly to see if I could find its scientific name and found that it was actually a male Striped (or Lined) Horsefly, Tabanus lineola. I’d never seen one before. And, of course, once I find something new to me, I have to research it more.  Never having encountered a Horsefly before, I was surprised to learn that although the males drink nectar, the females drink blood (usually from large mammals like livestock). She had scissor-like mouth parts that slice into the skin so she can get to the blood. This species is usually found along the east coast and Gulf of Mexico, so it was something of a surprise to find it here… assuming I got the ID correct.

We also got to see a male Red-Winged Blackbird flaring his epaulets at a female, and a pair of Brown-Headed Cowbirds performing what we thought was courtship behavior.  The two birds sat across from one another, then one ruffled its feathers, opened its wings a bit and bowed down at the other, and the other responded in kind.

Roxanne and I inferred the behavior was “courtship” but, from what I read, after I got home, what we were seeing was actually two males trying to outdo one another in a machismo contest.  Apparently, the females don’t respond well to the males’ bows, which they see as aggressive, so the males only bow to one another. (You can read more here.)  The males open their wings to one another, and to females, to show how mature they are. Juveniles have pale markings on the inside of the wings.

You can see the video snippet I took of the birds HERE.

And we found a couple of Black Phoebe nests, one stuffed full of babies who were almost fully fledged. They were stacked up, one on top of the other, with their tails sticking out over the edge of the nest. And toward the end of the auto tour route we came across a dead tree where there was a Western Meadowlark, a Red-Winged Blackbird and a tiny Song Sparrow all singing their respective songs.

We caught glimpses of American Goldfinches and Bullock’s Orioles, and hear Bitterns, but didn’t see any. One oddity was sighting a Mute Swan in the permanent wetlands area. That was odd because swans hardly ever go into the refuge, and Mute Swans are actually an invasive species. Unlike the Tundra Swans, the Mute Swans are super-aggressive and destroy the habitat they live in by ripping up water-plants from the roots.

When we were done at the Sacramento refuge, we decided to go over to the Colusa National Wildlife Refuge to show Roxanne the day-roost of the Black-Crowned Night Herons at the end of the auto-tour there. We were astonished to discover that the auto-tour there was roped off so no one could get to it… but the rope and signage was only visible AFTER you entered the refuge and started driving down the route. Stupid. They should have put the signs on the front gate or in the parking area.  A “manager” who showed up a little while after did, said that the auto-route was shut down because they were short handed and couldn’t patrol it well enough. Sad.

So, we didn’t do that tour and instead walked around a little bit in the native flower garden they have near the restroom facility.  Along part of a path near the garden, Roxanne found some galls we’d never seen before: the gall of the Elm Balloon-Gall Aphid, Eriosoma lanuginosum.

According to what I’ve read, the galls are initiated by a “fundatrix”, a parthenogenetic female aphid whose presence causes an extreme enlargement of the soft cell tissue on one side of the leaf. The galls are hollow and feel rubbery. They start out green and are covered with fine white hairs (which we saw) and turn brown as they age.

Inside the gall the fundatrix has her babies which are wingless and yellow until they mature. There can also be second generation aphids, called “alates” (usually winged individuals) which are dark green to black and wax powdered. Not all of the adults grow wings, however, and wing-growth seemed to be associated to crowding inside the galls, a short supply of food, and/or changes in the environment. Nature is so cool!

After walking around a bit, we headed back home to Sacramento and got there around 3:00 pm.

A Little Bit of Everything, 04-24-19

I got up around 5:30 this morning because the dog needed to get outside. Since I was up, I decided to stay up, and after giving the dog his breakfast, I got dressed and went out to the Effie Yeaw Nature Preserve for my walk. I was sunny and already about 53° when I left the house. When I got back home around 11:00 am it was 78°.

During my walk I saw but couldn’t get photos of a couple of Bullock’s Orioles, a male Rubyspot damselfly, and several White-Lined Sphinx Moths. The Rubyspot was a bright red male, and I was so bummed that I wasn’t able to get a photo of it. The Orioles and Sphinx moths were whizzing around, so I couldn’t get my camera to focus on them. Gotta be fast when you’re photographing nature!

CLICK HERE for the album of photos.

I was able to get photos of other critters including an Oak Titmouse with a small caterpillar in its beak, a Turkey Vulture sunning himself on the top of a tree, and several Western Fence Lizards including a male courting a female, and another female who looked really gravid (pregnant, full of eggs).

A one point along the trail I found a nesting cavity in the side of a tree and saw Tree Swallows, an Acorn Woodpecker, and a House Wren all seemingly fighting for it. The Tree Swallows out-numbered the other two species at the tree, so I’m assuming they’re taking that spot.

I also found a couple of squirrel dreys (nests), including one near the Maidu Village near the nature center. The squirrels there had pulled tules out of the tule hut on display and used them in their nest. Hah! And I found a Bushtit nest in a spot where it was surrounded by Pipevine.

The Pipevine Swallowtail butterflies were flittering all over the place. At on spot, I came across a vine where the caterpillars hat just hatched from their eggs and were busy eating the shells. Another cool sighting was a Snakefly. I found a female (obviously by her long dagger-like ovipositor) sitting on a leaf and got a photo and video snippet of her before she rushed away.

So, it was a good walk.
