Looking for Willow Galls, 06-09-19

I got up around 5:30 this morning, and after giving the dog his breakfast, I headed over to the American River Bend Park.  I was in search of willow galls and found oh-so-much more.  The weather behaved itself in the morning hours.  There was a breeze by the river, so it didn’t get too warm for me to walk until around 10:30.  So it was a nice morning. 

First I tried walking along the river at the first pullout, but the water was too high there, so I took a trail that brought me out onto the sandy area close to the bridge.  Lots of willows there, and I found the pinecone-like galls of the midge Rabdophaga strobiloide. They start out looking like little round balls of tightly packed leaves. Then they develop a “beak” that makes them look like pinecones. Each gall contains one midge larva. When the larva matures into an adult midge, the midge escapes the gall through the tip of the beak.

While I was walking through that area, I could hear the nattering of quail in the underbrush, but they kept themselves well-hidden, so I never did see them or was able to get a photo of them. I did get shots of a Spotted Towhee and a House Wren, though. I walked along that part of the river for a little while and then headed back to where I’d parked the car at the pullout.  At one point, the trail was blocked by a fallen tree. My trying to navigate over that obstacle was mildly humorous. Sit on one part of the trunk, lift my leg up, throw it over the other part of the trunk, try to get that foot to touch the ground, then shift my weight, and try to drag my other leg up over the trunk… Phew!

Once I got back to the car, I drove further int the park, got out, and continued my walk along the trail that runs along the riverside, but about 10 feet above the level of the water. I found a few Pipevine Swallowtail caterpillars and saw some of the butterflies flitting near the top of the trees. When the caterpillars ready to build their chrysalis, they attach their back feet to a tree (or other substrate) with silk, and then build a silk sling-shot-like thing that holds them upright but at a slight angle from the tree. (The silk is pulled from spinnerets on the sides of the body.) Then the caterpillar leans back and just hangs there in a kind of torpor as the chrysalis forms UNDER its skin. Once the chrysalis is formed, the caterpillar sheds its skin — including its face — and waits for metamorphosis to begin.

I also found some of their chrysalises. One was so new; it was still bright green. There stills seems to be a LOT fewer than I’m used to seeing out there, though.

At one spot, I stopped to watch a pair of House Wrens flying all over the place, the male singing brightly while he flew. They stopped off a few times at a cavity in an oak tree, only to be run off by some Tree Swallows.  Apparently, the Swallows had already claimed the cavity and were trying to keep the Wrens from setting up house there.  I got quite a few good shots of the Swallows.  The Wrens, not so much…

 

A nice surprise was seeing a female Common Merganser swimming near the shore with her three red-headed little ducklings. The mom was swimming up-stream which can be hard on the babies when the current is strong, so they sometimes swim in her wake… or just hop onto her back!  In one photo you can see the mom swimming with her face in the water. This is a typical fishing technique used by these birds; she’s seeing if there’s anything tasty underneath her.  These ducks are sometimes referred to as “saw-bills” for the serrated edges along the rim of their bill. Unlike Mallards, Mergansers are “diving” ducks, not “dabbling” ducks.

I walked for about four hours and then headed back home.  But another surprise happened when I was driving out of the park. I saw something moving near the edge of the road and stopped to get a better look. I realized it was a female Wild Turkey, that was sitting down in the dirt and dried gas.  She was giving herself a dust bath (to rid her feathers of mites). The surprise was when, right behind her, her baby (a little fledgling called a poult) stood up!  Mama turkeys are very protective of their babies, and when the mom realized I’d seen her kid, she got up and hurried him away from the road.

A Beaver, Babies and a Bison Snaketail

I got up around 5:45 this morning and headed out to the American River Bend Park for a walk.  I hadn’t been out there for quite a while, and wanted to see if the water plants were growing along the banks yet, and if the Pipevine Swallowtail caterpillars were starting to make their chrysalises.  No to the first one – sort of – and yes to the second one.  The weirdest sight was when I first drove into the park.  A female ranger was out by the kiosk and asked me to stop, so I did… And from across the driveway comes a mama Wild Turkey and her six fuzzy babies – and a male Peacock all walking along right in front of my car.  I couldn’t get my camera out of its bag fast enough to get any photos.  Dangit!  I wondered if this was the same Peacock I’d seen chasing the female turkeys several weeks ago… and if the babies could have been his.  The ranger said she didn’t think they could interbreed, but…  both birds are Galliformes, aren’t they?  I mean, peacocks are more closely related to turkeys than turkeys are to chickens…  What would you call the hybrids?  Teacocks? Perkeys?  Hah!  Wish I could keep an eye on that group and see how the babies look when they fledge…

When I pulled the car in further down the road and parked, I was right next to a tree where there were a lot of Acorn Woodpeckers, and I got some photos (and a little video) of one sitting in the nesting cavity.  At first glance I thought it was a female sitting on her nest, but it was a young male, so it must’ve been a fledgling not ready to get up yet.  Sleepy boy.

Then I came across some very tiny, shiny black beetle-like things on the leaf of a live oak tree.  I’d never seen anything like them; they seemed to have suck an odd shape and what looked like white spots in between the body segments.  I thought they must have been the larva stage of something, so I posted photos to BugGuide.net to see if someone there could identify them for me…

My next big find was spotting a large beaver eating roots and greens along the bank of the river.  It was right up the bank from me, and I was so surprised to see it that I just pointed my camera at it and started shooting.  I got some shaky lurching video of it, and a few still shots.  That was the closest I’d ever been to a live beaver.  It was exciting.  I think he would have stayed there for a while longer had I not tripped on one of the stones on the shore and startled him.  He took off into the water, slapping his tail down to make a big splash as he left.

Then I saw a female Common Merganser coming down the river with TWENTY little red-headed babies in tow.  The stronger ones were able to climb up onto her back when she sped up trying to get past me… Beyond. Cute.

Later on while I was stopping by an old Cottonwood tree to get some photos of lizard, a big male Twelve-Spotted Skimmer dragonfly decided to fly in and rest on a nearby branch, so I got some photos of him, too.  Further along, I saw a Bison Snaketail dragonfly land in the dried grass along the side of the trail.  I got some photos, but because the dragonfly is almost the same color as the grass, they don’t really show off how cool the dragonfly is…

Then I drove the car a little further into the park and walked along the trail that follows the river but stays well above it.  The water was high in the river and running pretty fast, so I didn’t see a lot birds on the shore… just a few Mallards and Canada Geese.  What I was really looking for on this part of the trail, though, was the Pipevine Swallowtail caterpillars.  During this time of the year they’re finishing up gorging themselves and turning their attention to getting up off the ground and forming their chrysalises.  I found lots of them.  Some still undulating around, some going into their torpor stage, and some already encased in their chrysalises.  While I was checking out the caterpillars on one tree, I was startled when a mama Tree Swallow flew past my head and went into her tree-cavity nest right across the trail from me.  I got some photos of her checking me out… along with some shots of the butt of a small House Wren who had a nest in the tree across from the Swallow’s nest.

On my walk, I also came across several mule deer, a Killdeer, an Ash-Throated Flycatcher, some Scrub Jays, fly-overs by a few Great Egrets and what looked like an immature Black-Crowned Night Heron, and a few different plants, flowers and galls. So it was a very eventful and productive walk.  I was out there for about 3½ hours and then headed out.
