Lots of Nesting Birds, 04-30-19

I got up around 5:30 and was out the door by about 6:15 am to go to the Effie Yeaw Nature Preserve for my regular Tuesday trail-walking gig. The weather was beautiful: about 53° when I got to the preserve and about 70° when I left. Sunny and a little bit windy.

I saw LOTS of birds’ nests: European Starlings bringing some twigs for the nesting cavity and some bugs and worms for the hatchlings. (I could hear the babies squawking inside the tree); Phoebes bringing bugs for their babies; an Oak Titmouse carrying fecal sacs out of her nest; a male House Wren showing a nesting cavity to a female, even going to far as to get into the cavity himself, stick his head out and sing to her. Hah!

Saw lots of squirrels, especially young Fox Squirrels who were running around, jumping, and putting just about everything they could into their mouths.  Generally, acting “squirrely”. Hah!

I found some caterpillars I’d never noticed before on the Redbud trees. They were pale green and had folded themselves inside the soft leaves of the tree.  You’ll never guess what they’re called…  Redbud Leaf-folder Moth caterpillars. Sometimes the names are like, “Duh!”, obvious.

I also found caterpillars on the leaves of the blackberry bushes, and these guys were tricky. They had an escape hatch, so if I touched the front of their silk “nest”, they would zip out the back and fall onto the leaf below them. Some of them had black faces and some of them had reddish-tan faces. I haven’t really ID-ed them yet.

And, of course, there were Tussock Moth caterpillars everywhere.  Here’s a video snippet of an active guy on the top of one of the water stanchions at the preserve: https://youtu.be/Bj9nZiy_EmI

I think I’d mentioned before about the fact that I was finding tiny dirt-clod turrets on the trail.  They look like “hoodoos”; y’know like the big stone ones at Bryce Canyon, but on a tiny-tiny scale.  I couldn’t figure out what was making them, so I put my naturalist students on the hunt for information. Naturalist graduate Deborah Dash sent me some photos of the Diadasia bees and the turrets they make, but all of the photos were from the top of the turrets not the side, so I couldn’t really compare them to the photos I had.  But, that tip led me to look up other Diadasia bees, and I think I found the right one.  I now believe these are the turrets of the “aggregate nests” of the solitary, native Mallow-Loving Digger Bee, Diadasia sp., subgenus Coquillettapis, This website shows how the turrets are created. So neat! (http://nathistoc.bio.uci.edu/hymenopt/Diadasia%20Coquillettapis.htm)

Near the end of my walk, I couldn’t understand why I was so frigging tired. Then I looked at the time and realized I’d been walking for FIVE HOURS!  Yikes!  I get so wrapped up in what I’m seeing on the trail that I lose track of time.

Lots of Springtime Insects, 04-20-19

I got up around 6:30 this morning and headed out to the American River Bend Park. It was overcast and in the 50’s when I went out, but by the time I got back home, around noon, the clouds were breaking up, and it was sunny and breezy for the rest of the day. Just lovely.

I wanted to see if I could find butterfly eggs at the park, and I was able to find some, but only on my way out. So, it was a long wait for the pay off, but I found a pipevine with several groupings of eggs on it. Actually, my photos turned into a kind of unintentional “study of pipevines” with pictures of the leaves, twining vines, seed pods, etc. It’s such a cool-looking plant.  In Victorian Era gardens it was all the rage; now people don’t plant it much anymore – and I think that’s partly because everything but the vines themselves die off each year, so it just looks “ropey” for half of the year.  It’s a boon to the Pipevine Swallowtail butterflies, though, who literally can’t live without it.

CLICK HERE for today’s photos.

While I was there, I saw a European Starling come out of her nesting cavity, so I waited by the tree to see if I could get a photo of her when she came back. Smart bird, though, she flew in behind me, making me turn as she went by, and went back into her cavity with an angry grumble.

I also saw some Wild Turkeys, including a leucistic female, and while I was watching them a bonded pair of Mallards came flying in and landed right near my feet. There was also a bonded pair of Common Mergansers on the bank of the river. These ducks are sometimes referred to as “Sawbills” because their bills have a serrated edge, which helps them hold onto the fish they catch. (They’re fish-eating diving ducks, as opposed to filter-feeding dabbling ducks like the Mallards.)

Saw lots of Craneflies (Mosquito Hawks) all over the place and Elder Moth caterpillars in the elderberry leaves. There were also a lot of Tussock Moth caterpillars, little nests of earwigs, some micromoths, and a mayfly that had just shed and was hanging next to its exuvia. This time of the year is soooooooooooooo interesting! I was surprised to see the earwigs snuggled in the tops of mugwort plants. I thought mugwort was a kind of natural insect repellent. I guess no one told the earwigs.

There were a lot of still-green Oak Apple galls in the trees, but I was really happy to come across some second-generation galls from the Live Oak Gall Wasp.  The first-generation galls are really obvious and visible: round balls covered in spines.  The second-generation galls are tiny and sit on the back of the leaves; they look like upside down volcanoes. Finding them is difficult, so I’m always excited when I get to see them.  The first generation of this wasp is comprised of all females that reproduce asexually, and the second generation is comprised of males and females that reproduce sexually. Cool, huh?

And while I was watching a male House Wren, I saw him look down below him. There was female down there with a feather in her beak. I’m assuming they had a nesting cavity near there somewhere and she was literally feathering her nest. Awwww!

I overdid it again today – because there’s so frigging much to see – and didn’t get back home until around 11:30. Four-and-a-half hours of walking; my body was really mad at me for the rest of the day.

A Very Hairy Butterfly Encounter, 04-06-19

I led some of my Certified California Naturalist students on a walk around the Effie Yeaw Nature Preserve.

My coworker Bill Grabert and our volunteer Roxanne Moger joined me. There were about 10 of us altogether. Because the nature center was hosting a donor event today, we stayed out of the parking lot and parked along the road that leads out of the preserve. It was about 52° when we got there, and it made it up to a mostly cloudy and overcast 68° by the afternoon.

A female coyote surprised us by stepping out into the parking lot and trotting down the road – too fast to get any photos of her. But otherwise, we saw mostly the usual suspects during the walk, but there were some deer that were being very cooperative, some of the wildflowers were showing up, and we saw quite a few nests and nesting cavities, including the Mourning Doves’ nest, a Red-Shouldered Hawk nest and several Bushtit nests.

Students also learned how to identify some of the local birds by their calls and saw their first pair of Common Mergansers – which was kind of a big deal to them because the males and females look so totally different from one another. Most of them recognized the female (with her reddish head and topknot), but the male (with his bright white breast, iridescent blue-green head and orange bill) was a big surprise to them.

The leucistic male turkey was also a first for many of the students, so that was fun to see.

The funniest thing that happened on the walk was when a female Pipevine Swallowtail butterfly flew into the hair of one of the students, Sue. Then Roxanne found a cooperative male butterfly and put him into Sue’s hair so everyone could see how to distinguish the males from the females (by the amount of blue on their hind wings). Sue was very patient and stayed still as everyone talked about the butterflies and took photos. Hah!

The subspecies of Pipevine Swallowtail, Battus philenor hirsuta, we see around here is endemic to the Central Valley of California and is found nowhere else on Earth.  And the word “hirsuta” refers to the “hairy” body this subspecies… so it was a very Hairy Butterfly Encounter.  Coolness.

We walked for almost 4 hours before heading out and going back to our respective homes. I’ll be doing another walk on Tuesday next week for any students who still need to add a field trip to their course requirements.
