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.

Wildflowers on Bear Valley Road, 04-13-19

I got up around 6:00 this morning, planning on going out on a wildflower tour with my coworker Nate and volunteer Roxanne.

Nate sent me an email, however, saying that his folks were in town and when they heard what he was doing today, they wanted to go with him – so there went Roxanne’s and my seat in his car.

I texted Roxanne and asked if she’d like to go with me, and she offered to drive. So, around 8:00 am we headed out to Highways 16 and 20 and Bear Valley Road (in Colusa County) – about an hour ahead of Nate and his group.  Because we were following almost the same route as Nate, though, our paths crossed a few times. He caught up with us at two spots where we had stopped to look at and photograph the wildflowers, and we passed him a couple of times.

Unlike the last time I went out looking for the wildflowers, today’s excursion was incredible, and Roxanne and I ended up spending the whole day outdoors.  I saw some insects and plants I’d never seen before, and the fresh air, exercise and views of flower-painted landscapes was exhilarating. It’s so nice to go on an excursion like this with someone who moves at a browsing pace like I do, and who gets excited by bugs and flowers and the sight of ducks in the river. Hah!

There were soooooo many photos, I broke them down into two albums.

Roxanne and I didn’t get home until around 6:00 pm. It was a long but fun and nature-filled day. I took over 1200 photos, so it’s going to take me a while to get through all of them.
