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.

The Baby Deer Has a Bad Cough, 06-30-18

I got up around 5:00 am, and headed out to the Effie Yeaw Preserve again before it got too hot outside. It’s supposed to get up to 103º today. It was 61º at the river when I got there, and by the time I left at 8:30 am it was already 78º. Ugh!

CLICK HERE for the full album of photos.

When I drove in, there were Yellow-Billed Magpies and American Robins trying to snatch up early morning bugs near the kiosk.

By the nature center, a male Anna’s Hummingbird posed in a tree long enough for me to get a few photos of him.

I watched as a Wild Turkey went up to a blue elderberry bush and jumped up and down to snag the ripe berries from it and pulled them to the ground. At another spot, I was standing under a wild plum tree, and Scrub Jays were in the branches knocking the plums down. Almost got hit by some of those!

Further along the trail, I got to see a pair of American Kestrels in the top of a tree; a little male and a female. They’re so talkative! I also got to see a Red-Tailed Hawk, and a juvenile Turkey Vulture (along with some adults). You don’t get to see the juveniles very often, so it’s always kind of a treat when they’re out and about.

The young fawn and its mother that I’ve seen on my last few trips to the preserve has come down with a horrible cough. It always looks kind of skinny and scrawny to me, but I’d never heard it cough so much before. I looked up pneumonia in deer and apparently, it’s a thing. It affects Big Horn Sheep and White-Tailed Deer more often, but can affect Black Tailed Deer, especially if they’re living near water in a confined space (as they sort of are at the Effie Yeaw Preserve). I don’t know if the preserve staff can do anything for the baby, but that cough is surely going to make him a target for the local coyotes. It’s loud, and it advertises that the fawn is in poor condition. His mom also looks like she might be pregnant again, so I don’t know how she’ll manage with a newborn and a sick yearling… Poor baby.

In one of the ant colonies I cam across, winged adults were emerging, getting ready to start a new nest somewhere else. They were emerging out into the sun, but when I stepped closer to the ant hill to get some photos, by shadow blocked the entrance – and they all went back inside. When I stepped away again to let the light hit the entrance, they all came back out again. Interesting.

And it seems to me that the oak trees are getting awfully full of acorn buds this year. Maybe we’ll have a mast year this fall?
