A Very Hairy Butterfly Encounter, 04-06-19

I led some of my Certified California Naturalist students on a walk around the Effie Yeaw Nature Preserve.

My coworker Bill Grabert and our volunteer Roxanne Moger joined me. There were about 10 of us altogether. Because the nature center was hosting a donor event today, we stayed out of the parking lot and parked along the road that leads out of the preserve. It was about 52° when we got there, and it made it up to a mostly cloudy and overcast 68° by the afternoon.

A female coyote surprised us by stepping out into the parking lot and trotting down the road – too fast to get any photos of her. But otherwise, we saw mostly the usual suspects during the walk, but there were some deer that were being very cooperative, some of the wildflowers were showing up, and we saw quite a few nests and nesting cavities, including the Mourning Doves’ nest, a Red-Shouldered Hawk nest and several Bushtit nests.

Students also learned how to identify some of the local birds by their calls and saw their first pair of Common Mergansers – which was kind of a big deal to them because the males and females look so totally different from one another. Most of them recognized the female (with her reddish head and topknot), but the male (with his bright white breast, iridescent blue-green head and orange bill) was a big surprise to them.

The leucistic male turkey was also a first for many of the students, so that was fun to see.

The funniest thing that happened on the walk was when a female Pipevine Swallowtail butterfly flew into the hair of one of the students, Sue. Then Roxanne found a cooperative male butterfly and put him into Sue’s hair so everyone could see how to distinguish the males from the females (by the amount of blue on their hind wings). Sue was very patient and stayed still as everyone talked about the butterflies and took photos. Hah!

The subspecies of Pipevine Swallowtail, Battus philenor hirsuta, we see around here is endemic to the Central Valley of California and is found nowhere else on Earth.  And the word “hirsuta” refers to the “hairy” body this subspecies… so it was a very Hairy Butterfly Encounter.  Coolness.

We walked for almost 4 hours before heading out and going back to our respective homes. I’ll be doing another walk on Tuesday next week for any students who still need to add a field trip to their course requirements.

Lots of Deer and a Squirrel Stuffing Her Face, 11-17-18

After giving the dog his breakfast, I headed over to the Effie Yeaw Nature Preserve for a walk. The air quality has been so bad that the zoo and other recreation places in Sacramento have all shut down for the day. The nature center at Effie Yeaw was also closed, but the trails were still open.

It was about 38° at the river, so I could see my breath in the cold air; and it got up to about 60° by the afternoon. I don’t know how much the smoke is affecting the local temperatures, but I’m sure it’s contributing to the lows.

The first thing I saw when I went into the preserve was the big 4-pointer buck (now working on 5 points) with his harem of does.  In my head, I refer to him as “Big Boy” because of the size of his rack.  He was hanging out in the meadow right next to the picnic area, so I was able to get quite a few photos of him.  As I watched him, a spike buck (1-point) approached, following after a doe who had a fawn with her.  The fawn was pretty good-sized and out of its spot, but still considerably smaller than its mom.  The doe headed deeper into the meadow and the spike buck followed her but was cut off by Big Boy who then tried to get the doe into his own harem. The fawn got spooked and ran toward the harem while its mom was being pursued. She wasn’t receptive to either one of the boys and pretty much ignored them. I didn’t hang around there long enough to see when she reunited with her fawn.

At different points along the trail I saw other deer: some lone does, some small herds, and some of the other larger bucks, including a 3-pointer who, oddly enough, seemed to have the center of his back shaved. There was a large spot that was completely hairless, and the margins of the spot were too clean and symmetrical to have been natural (like mange or something). I couldn’t see any suture marks or anything that might have suggested the buck had gotten medical attention, so I wonder what had caused the bald patch. (I guess I’ll have to call him “Baldy” for now.)  The obvious “flaw” in his coat didn’t seem to detract from his attractiveness to the does. He had his own small harem of three or four of them.

When I was walking away from the 3-pointer and his group, a male photographer came up the trail. “He walked right by you, didn’t he?” he said, referring to Baldy.

“Yeah. He’s got some females with him right now.” I said.

The male photographer then joked that the deer weren’t cooperating with him much, but the squirrels were posing for him everywhere he looked. He even struck a couple of squirrelly poses to demonstrate. Hah!  I’d gotten a lot of squirrel photos, too. They were all over the place: California Ground Squirrels, Western Gray Squirrels, Eastern Fox Squirrels… I got photos of some of them chewing on black walnuts, and one female literally stuffing her face with grass and leaves for her winter nest.  So funny.

I also came across solitary deer throughout the forest; some camouflaged so well in the gold-brown grass that I was only able to see them because their silhouettes gave them away. I saw the doe with the peculiarly long, thin face (“Long Face”); she’s very distinctive. At one spot on the trail, I could HEAR the deer before I saw them.  There was a small group of does and fawn that were very loudly crunching on acorns (which are plentiful this time of year). They needed to eat with their mouths shut. Hah! I guess they felt safe enough, though, to make that much noise.

One of the obvious things all along the trails today was the coyote scat. It seemed to be on every trail; some of it very fresh. I must have just missed seeing some of the coyotes.  I think, though, that a coyote is what caused a flock of Wild Turkeys to take off en masse from the top of a hill and fly down, right over my head, into the woods. Those things are BIG; I was surprised when none of them hit me or crashed into anything.

A neat sighting was a male Western Bluebird sitting on top of a bat box along the Natoma Trail. There are a few bat boxes on posts throughout the preserve, but I don’t think they attract very many bats. The boxes look too “exposed” to me; they get the full sun in the summer months. Bats need darkness and protection to sleep in during the day; I doubt that those sunny “saunas” are attractive to any of them.  I’ve seen lots of different birds use the boxes as perches, though, like the Western Bluebird, so I guess they’re not a complete waste.

On my way out of the preserve, I came across a couple of volunteers who were taking the nature center’s “animal ambassador” bird out for some air.  One was Wak-Wak, a female Peregrine Falcon, and the other was Orion, the Swainson’s Hawk I’d seen the last time I was there. Wak-Wak had been accidentally shot by hunters (who then rescued the bird and brought it in for care), so one of her wings is permanently mangled and she can’t fly.

I walked for about 3½ hours and then headed back home.
