City Nature Challenge, Day 3, 05-01-22

It’s the City Nature Challenge Day #3 and my friend Roxanne and I went over to the American River Bend Park with my dog Esteban to look for more species to add to our totals. Esteban walked the whole trail along with us and never complained or asked to be picked up and held. I was very proud of him. The weather was lovely: cool and breezy. It was so nice.

There were so-so many California Pipevine Swallowtail caterpillars everywhere. We even found one that was just starting to go into it’s metamorphosis. CLICK HERE for an excellent video (not mine) about the butterfly’s life cycle.

At one spot, we noticed that a White-Breasted Nuthatch was whizzing back and forth with food for its babies, and followed it back to its nest: a hole at the end of a downed log in the grass. It’s usually really difficult to get clear photos of this species of bird because it’s small, moves a lot, and usually has its back to you. But at this particular nesting site, we were able to get quite a few face and full body photos of the birds.

There were a lot of tiny House Wrens singing from various trees all around us, but it took a while before we were able to find one that was within photographing range.

Roxanne had really wanted to see some of the Rough-Winged Swallows I saw the last time I was at the park, but they were being shy today. We finally did see a few in flight, and one landed on a tree nearby, so at least she was able to get pictures of that one.

In the river, we saw a pair (male and female) of Common Mergansers. In this species, the males don’t look anything like the females (sexual dimorphism). According to Cornell: “…Adult sexes strongly dimorphic in size and plumage most of year. Male has iridescent, greenish-black head with rounded crest, brilliant white neck, underparts, and secondaries contrasting with black upperwings, gray back and tail, and long narrow scarlet-orange bill. Female plumage has rusty-brown head with long crest and distinct white chin patch, slaty-gray breast, back, wings and tail, white flanks and belly, and scarlet-orange bill; brown of head and upper neck sharply demarcated from white lower neck..” I’m looking forward to them having lots of red-headed ducklings.

A big surprise, for me, was seeing my first Townsend’s Warbler: a little yellow guy with thick black eyeliner. So cute.  This species is migrating through right now, and flies between because Alaska and Central America each year. The species hasn’t been studied very much, so most of the information on it is anecdotal.

Throughout the park, we found several different kinds of lichen, and also were able to find an identify a few species of grasses.

On our way out, we spotted a mama Wild Turkey with about four or five little poults. As soon as she realized we were trying to get photos of the babies, she hurried them into the long grass where they were all but invisible – except for the grass-tops moving over them.

We were out for about 3½  hours and then headed home. This was hike #23 in my #52Hike Challenge for the year.
