I headed out to the Effie Yeaw Nature Preserve. It was about 56° when I got there, but it was up to around 75° when I left. When I got there, I was happy to see my friend and fellow-naturalist Roxanne there, too. She’s helping me out with the Monarch monitoring facet of my volunteer work at the preserve. I really appreciate her help, too, because it makes the somewhat tedious process of looking over each milkweed plant go more quickly.
Still no sign of Monarch eggs or caterpillars, and what was odd was we didn’t see much in the way of other insects either. We did find some spiders (including a White Crab Spider and a little Jumping Spider), some aphids, a single praying mantis, and a couple of beetles but that was it. The lack of critters was rather surprising and made me wonder if the area had been sprayed or something. We worked on the plants for about 90 minutes and then went for a short walk through the preserve.
Although we heard a lot of different birds, we didn’t see any Wild Turkeys today, which was very unusual. They’re normally all over the place. We came across two bucks but no does and no fawns. Both bucks were in their velvet. One was a nervous youngster who was just getting his first antlers (a “spike buck”), and the other was a laid-back 3-pointer who was just lying in the grass on the side of the trail. He kept an eye on us but didn’t move from his spot. I guess he figured we were no match for him, so we weren’t much of a threat. He was gorgeous. And because he was so still, we were able to get quite a few good photos of him.

The most exciting thing to me that we came across on our walk was sighting a few different species on a Blue Oak tree (Quercus douglasii) along the River Trail. It had both Saucer Galls (Andricus gigas) and newly budding Crystalline Galls (Andricus crystallinus). The saucers start out flat and then form cups (some with smooth edges and some with serrated edges). The Crystalline Galls start out like tiny dark-pink urns and then swell up and get their sparkly spines. We hadn’t seen any galls at all on the “Frankenstein” hybrid tree further up the trail, so finding the galls on the Blue Oak by the river was rewarding.
It was nice to see that this particular
Blue Oak was also getting acorns on it. These oaks don’t produce acorns in drought
years, and when they do produce acorns, they’ll produce a lot one year (a “mast”
year) and then produce far fewer for the next two or three years. So, as I said, it was nice to see this one
with acorns all over it. (The acorns
usually take a year to develop.) Blue Oaks are also endemic to California,
which means they’re found here and nowhere else on the planet. It’s also one of the oak trees that is immune
to the fungus that causes Sudden Oak Death.
Very cool trees.
Oh, and we found a Treehopper – but it jumped away before I could get a photo of it. Those things are sooooooo weird-looking with their hunched backs. The one we saw was a Buffalo Treehopper (Stictocephala bisonia): mostly green with some burnished gold edges on it.
We walked the trails for about 2 hours.
