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.

My First Glimpse of Fawns This Year, 07-02-19

I got up around 5:30 this morning so I could get over to the Effie Yeaw Nature Preserve and begin my monitoring of my milkweed plot there for evidence of Monarch Butterflies. I finished that (with the help of my friend and co-naturalist Roxanne Moger) around 8:30.

It was still relatively cool outside, so Roxanne and I decided to put our tools back into our car and walk for a little while.  We came across some cooperative squirrels and a Desert Cottontail rabbit, and also checked out the tree where I’d seen the feral beehive earlier.  There were about three times as many bees at the spot, so I’m assuming the queen has decided to set up shop there.

 The surprise sighting was coming across another doe – with twin fawns!  She was keeping them well-hidden in the shade and tall grass, but we were able to catch glimpses of them. And we couldn’t help but chuckle when the babies went stotting through the grass with mom chasing after them.  They’re so tiny but soooo active! They’re the first fawns I’ve seen this year and that’s always exciting.

As we were leaving the preserve, I could hear a Ground Squirrel’s alarm call and looked around to see if I could spot what the trouble might be. I saw movement overhead and spotted an adult Red-Shouldered Hawk fly overhead. It landed in a nearby tree and then sat there for quite a while, so we were able to get quite a few photos of it.  So, even though our walk was only a single loop, we got to see quite a bit… which is always fun.

Lots of Fledglings and Other Critters Today, 06-30-19

I got up around 5:30 this morning and immediately headed out to the Effie Yeaw Nature Preserve for my weekly volunteer trail walking thing.  It was cool, around 55°, when I got there, but as soon as the sun got up a little higher in the sky it started to heat up.  It ended up around 75° by the time I left the preserve.  There were some latent clouds overhead which meant it was humid, too. Not my favorite.

Along with the usual suspects – deer, Acorn Woodpeckers and Wild Turkeys – I got to see quite a few fledgling birds out today.  The fledglings are fully feathered and the same size as the adults, but not quite adept at flying yet, so they spend a lot of time around ground level begging their parents to feed them.  They’re so bossy!  I watched one little House Wren fledgling sitting on top of a pile of old tree limbs.  For a while, he tried posturing like the adults do with his little tail standing straight up behind him, but then he got tired and just sat and dozed… until he saw or heard one of his parents flying by. Then he’d perk up and open his mouth wide expecting food to be dropped into it. Hah!  Although I could see the parents flitting around where he was, they also had other fledglings in the nearby shrubbery (which I could hear buzzing away), and because I was standing between the shrubs and the baby on the woodpile, they wouldn’t go near him. After getting quite a few photos of the little guy, I decided I’d better move on or he wouldn’t get fed at all.

I also came across two fledgling California Towhees.  Now, the California Towhees usually look kind of obese and drab to me, but the babies… they were soooo scrabbly looking; total bed-heads!  They were sitting close to one another with their feathers all fluffed out, so they looked extra fat and messy. Made me chuckle.  One was content to sit and wait for their parents to bring breakfast, but the other one was extra hungry, I guess, and kept tugging at the dead grass near them trying to get something out of it. Can’t get milk out of a stick, son. Sorry.

Further on along the trail I could hear a parent and fledgling Red-Shouldered Hawk calling to one another.  The fledgling was very loud and persistent, demanding to be fed, and the parent would call back him as if to say, “Shut up! I’m working on it!”  I eventually came across the fledgling sitting up in the bare branches of a tree. (He was so loud he was announcing to everyone exactly where he was.)  He saw me and tried to scramble away to other branches but was still unsure of how to make his wings work, so he looked pretty clumsy.  He stuck to the shadows as much as he could then, but I was still able to get a few photos of him.  (And I’m assuming he was a male based on his coloring; females are usually larger and have less vivid colors.) 

I also found one of the parents, sitting quietly now in the low branches of another tree right along the side of the trail, just above eye-level, ignoring the fledgling. Totally habituated to people, it didn’t move from its perch, but kept its eye on me as a passed by and stopped to take some photos. I think they’re such handsome birds.

Among the other things I found today were a few Pumpkin Galls on the leaves of a Live Oak tree. It’s kind of early in the season for those, so I was surprised to see them.  They’re super-tiny galls, and if you don’t know where or how they develop you’d completely miss them. Right now, they’re pale green, but come fall they’ll turn dark orange and fall off the leaves onto the ground were the little larvae will pupate through the winter.

I found a few Eastern Fox Squirrels and some California Ground Squirrels.  I was surprised to see one of the Fox Squirrels climbing through poison oak and eating the berries! Yikes!  I mean, I knew that the toxin in poison oak don’t generally harm wildlife, but I’d never actually seen any of the animals eating the stuff before.  I also saw a Fox Squirrel eating the husk off of a black walnut and watched a Ground Squirrel eating the tops off of some other plants.  (I think that gal was blind on one side, but once she saw me she moved too fact for me to get photos of her blind side.)

The other cool thing I spotted along the trail was that feral honeybees have found the tree along the Pond Trail again and seem to be setting up house there.  I saw them last year (I think it was) checking out the big opening in the side of the tree, but they left the site after a few weeks.  I guess the queen didn’t like it.  Now the opening is more covered with plants, so maybe it will feel more “protected” to them and they’ll stay there this time.  I let the gals in the nature center know they were there, so hopefully they can discourage hikers from walking off the trail to see the bees. We’ll see.
