This is first day of the City Nature Challenge. I pledged to post at least 50 observations to iNaturalist during the challenge this year so we’ll see how I do. It goes through the 27th.

I got up around 5:30 so I could get Esteban pottied and fed before I headed over to the Effie Yeaw Nature Preserve. I got there around 6:15 am and hung around the entrance until my friend Roxanne joined me there. While I was there, I got photos of some Coyote Brush Bud galls, ladybeetle nymphs (lions) and pupal cases, spiders, aphids, a tick, and plant bug nymphs, among others.

Surprisingly, we HEARD quite a few birds, but didn’t really SEE many. Instead, most of our observations turned out to be plants and “little things” like the bugs and galls.
We found a Leaf Gall and a kind of fimbriate gall on the Valley Oak leaves. I’d never seen the fimbriate one before, so that was a cool new finding for me. And we also found a Round Leaf Gall on a Live Oak leaf that was also new to me. I’d seen photos of ones on Black Oak before, but never saw anything like that on the Live Oak. All of them were listed in Russo’s book, though, which is kind of like my “gall Bible”.

The Valley Oaks are bursting now with new Oak Apple galls (also created by cynipid wasps) of all sizes. When they’re new, they’re bright green and some are blushed with plink.
Among the insects we saw, we found several specimens of a fly that was new to me, too: a White-Winged March Fly. It’s a narrow-bodied black fly with white hairs on its body and translucent white wings. It’s eyes are huge and cove the majority of its head; they’re surrounded by a ruff of fine black hairs. Really cool!

I took photos of several different kinds of grasses. I usually avoid those because they’re so difficult to ID correctly. Even when I loaded them up into iNaturalist, I couldn’t get past “grasses” as an identifier. I was able to ID two, though: Sweet Vernal Grass and Bristly Dog-Tail Grass. When I was taking some macro photos of the Dog-Tail Grass, I realized there was a tiny spider on it and he had bugs in his web.
There were a few more wildflowers out (although in the recent heat, they’re fading fast), and we saw out first Small-flowered Catchfly flowers of the season.
Of the very few birds we saw was an Acorn Woodpecker moving in and out of her nesting cavity, and a Black Phoebe collecting insects for her nestlings. We’d watched her during previous weeks building the nest. We were surprised to see that she was apparently working on her own. Usually, the Phoebes around the nature center work in pairs (a mated male and female) to feed the kids… and we wondered if something had happened to her mate.

The Red-Shouldered Hawk mama was in her nest, too, and we think she’s still sitting on eggs. We don’t see the white heads of babies through the covering leaves around the nest yet, and when there are hatchlings, mom and dad tag team to find things to feed them.
We were out for almost 4½ hours trying to take photos of as many things as we could to add to our iNat observations online. By the end of today, I think I have over 100 species to post on the site. Because of COVID-19 and the stay-at-home orders everywhere, this year’s City Nature Challenge isn’t going to be a contest, but I still want Sacramento to get some big numbers, so I’ll post whatever I can.
I got home a little after 11 o’clock and spent part of the afternoon posting about half of our sightings to iNaturalist before crashing for the day.
Post Script:
This is what the City Nature Challenge leader board looks like right now. Sacramento is 5th in the state and 23rd worldwide. I’m #10 on the Sacramento list for observations and Roxanne is #12. Woot!
