Lots of Snowy Egrets, 05-31-19

I got up about 5:30 this morning, fed the dog his breakfast and then headed out to the Cosumnes River Preserve for a walk.

There was little to no water in the “wetland” areas, so not a lot of birds or dragonflies. I walked along the slough on the side of the road, and then walked through the oak woodland to the nature center, and then back to the car.  Along the slough, I saw Tree Swallows, a pair of Western Kingbirds, and a trio of Brown-Headed Cowbirds doing their bowing thing. They were on the top of a tree, so bowing was difficult, and they kept rolling off their twiggy branches. Eventually, they gave up and flew off.

Further along, I came across a small flock of Snowy Egrets who were feeling for things in the water with their feet.  As I was watching them and taking pictures, a Great Egret flew in and joined them. Seeing the great Egret and the Snowy Egrets side-by-side really exemplifies their size difference. It looked like a mama bird with lots of babies around her.  Some of the Snowy Egrets were flashing their top knots at one another. I got the sense that it was a more an aggressive, territorial thing than a romance thing. None of the birds had their long, trailing feathers in; and none of them were sporting the pink blush in the face the Snowies get when their breeding.

Beyond the regular Oak Apple galls, there weren’t a lot of other ones out yet. I saw some Red Cones just starting to grow – looking like tiny red pimples on the leaves of some of the Valley Oaks.  I did see the curling leaf galls and “flower” galls on the ash trees, but not as much as I’m used to seeing.

As I was walking through the oak woodland, I was surprised to see a large flock of American White Pelicans fly overhead. By the time I got my camera up and focused, though, they were gone. It’s always so neat to see those big birds flying.  They don’t look like they should be able to stay aloft, but they’re so graceful in the sky.

I also got a glimpse of a Green Heron when he flew out from the rushes around the bridge area, and up into a willow tree.  There were so many twiggy branches around him, though, it was hard to get any decent shots of him.

Near the nature center, I saw some House Finches, Anna’s Hummingbirds, and a baby cottontail rabbit. The baby was a surprise; my brain couldn’t get itself around how small it was at first, and I just stared at it. I did come to enough to get a few shots of the bunny before it scrambled away, though.

Even going down to the boat launch area, I was surprised by the lack of insects. I was hoping to see dragonflies, damselflies and spiders there, but… nothing.

I walked for about three hours and then started to head home.  My insides were starting to complain, and I hurried to the restroom near the boardwalk area where my car was parked – only to find that the thing was locked shut. Seriously?! Guh! I hate it when that happens.

An Overcast Day at the Preserve, 02-28-19

Date: Thursday, 02-28-19
Time: 7:30 am to 10:30 am
Location: Effie Yeaw Nature Center, 2850 San Lorenzo Way, Carmichael, CA 95608
Habitat: Oak Woodland and riparian boundary
Weather: Overcast, 43° to 46°

Narrative: I headed out to the Effie Yeaw Nature Preserve for my trail walking right after I fed the dog his breakfast. I arrived about 7:30 am and it was 43° at the river. The first thing I saw when I got into the preserve was a Red-Shouldered Hawk just sitting on the lawn. It hadn’t caught anything (that I could see) and stood there, looking around for a short while, so I was able to get some photos and a video snippet of it before it flew off into the trees.

After going down the wooden steps onto the Bluff Trail, I caught sight of a Western Gray Squirrel running along the trail with a mouth full of grass and twigs, so I followed it… and found where it was constructing its “drey” (squirrel nest). Dreys are different from other squirrel nests because they’re formed on the outside of a tree or cavity and built where several branches come together. ((If the squirrel’s nest is inside a tree or cavity, it’s called a “den”.)) If it continues to build there, walkers should be able to get some good views of the squirrel and its babies.

Lots of deer were out, including several small herds of does and their yearling fawns. I hung around one group for a while just watching a doe grooming her fawn. They’re so tender with their babies; it’s so relaxing to watch them. I also came across a couple of bucks, into two younger ones who were sparring for a little while. One or two of the does seem to be showing their pregnancies already. ((The gestation period is 7 months long so around 203 days.))

At one point along the trail, I saw two odd shapes in the top of a bare-branched tree. Because the sky was overcast, looking up into the branches everything was backlit, so it took a while for me to figure out what I was looking at: a pair of Wood Ducks (a male and female) looking for a place to nest.

I also came across more fungi today than I did on my walk with my naturalist student the other day. Puffball fungus, mushrooms, Elfin Saddles, and three different kinds of jelly fungus, including the nicest specimen of Witches Butter I’ve ever seen. I found a nice specimen of Trametes betulina, a kind of fungus that looks like Turkey Tail fungus (Trametes versicolor), but it has gills! It’s sometimes called the Multicolored Gilled Polypore or Mazegill. This is the first time I’ve seen it live and in such wonderful color. (I usually see it in its later stages when it’s just a bunch of hard weird gills.) Very cool.

Because it was early and overcast and a weekday, I didn’t see a lot of people, but had short interactions with those I did see: got to talk to one lady about Black-Tailed Jackrabbits and another about jelly fungi.

I walked for about 3 hours and headed back home.
