Blue Oak Galls and Other Stuff, 07-09-19

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.

Lots of Deer but No Fawns Yet on 06-13-19

I headed over to the Effie Yeaw Nature Preserve this morning and got there around 6:00 am and it was about 63° then. I was joined by “The Other Mary”, Mary Messenger, and we walked for about 4 hours.  We saw lots of deer today, mostly does with their older yearlings. Some of the gals were very “round” with their pregnancies. When the new fawns arrive, some does chase off the older kids… but others let them hang around for a couple of years. We didn’t see any fawns, but that’s to be expected. The does keep them well-hidden when they’re new. 

Along the shore of the river, we came across the mama Common Merganser and her three red-headed ducklings again. They were hanging around a pair of female Wood Ducks who had one slightly older duckling with them. We couldn’t get too close, so we had to be satisfied with long-distance photos.

We saw several Turkey Vultures, Cathartes aura, including one bird sitting in a tree and one sitting on a stump on the bank of the American River. The one on the bank turned toward us and lifted its wings in the “heraldic pose” so we could see its white under-wing feathers.  This pose, in which the Turkey Vulture turns its back toward the sun and opens its wings, is used by the birds when they want to warm themselves up quickly. 

The legs and some of the feathers of the vulture sitting in the tree were covered in dried feces (making them look white-washed). When it’s really hot, the Turkey Vultures will defecate their mostly white, watery feces on their legs and feet and then allow evaporation to help cool them off. As gross as this may sound, keep in mind that the vulture’s digestive system is so aggressive and their immune system is so high, that their feces come out virtually bacteria free and actually acts like a kind of natural sanitizer. Cool, huh? I wrote an article about the vultures in 2015. You can read it HERE.

We also stopped under the Red-Shouldered Hawk’s nest along the Pond Trail and saw one fledgling sitting in it. Where the nest is placed, it’s hard to get a good angle on it for photographs, so all we saw was the tippy top of the fledgling’s head.  Near the pond itself, we saw another fledgling, and near the nature center we saw an adult… So got a few photo ops on the hawks today.

This is the time of year when there are a lot of Western Fence Lizards scurrying all over the place, ad we were able to see quite a few of them, including a pair on a log. The stubby-tailed male was trying to court a female, but she just wasn’t that into him.  Hah!

We walked for about 4 hours and then headed back to our respective homes.
