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.

Mostly Starlings and Goldeneyes, 12-26-17

I headed over to the American River Bend Park for a walk. It was 34º when I got there, and got up to about 53º when I headed back home.

I wasn’t expecting to see a lot – we’re kind of “between seasons” at the river; all of the birds haven’t migrated in yet and it hasn’t rained enough for the fungi to come out – but the walks themselves always do me good. When I first got there, a light fog was still hanging over the river, so I went to the shore first to try to get some photos of that. Since the flooding earlier this year, the water had receded enough so that the riverside trail was passable again. (At the height of the flood, the river was right up to the trailhead, and beaver had floated up to chew on trees that normally wouldn’t have access to.)

Here is the album of photos and video snippets.

The flood has left its mark, though, with toppled down trees, scraggly flotsam high in the scrub brush and branches of still-standing trees, and rearranged rocks and sandbars. Still, the path was recognizable and I was able to make it through without incident. In places along the way, I could see the tracks of others who had walked along it: humans, dogs, deer, and what might have been a bobcat – fat rounded “fingers” with no toenails.

The trail let out close to what’s now the riverside, but I had to walk over tons of river rocks to get to the water. The rocks are all smooth and beautiful, but are a pain for me to walk across. My arthritis is welding all the bones in my feet together, so my feet don’t bend like they normally should anymore. Traversing uneven ground is a misery for me, but the few photos I got of the fog and a few birds were worth it.

The first creature I saw was a young Herring Gull, preening at the very end of a sandbar. He looked cold and sleepy, waiting for the morning sun to burn through the fog some more so he could warm up. Further up the shore was a Great Blue Heron, puffed up and hunkered down against the chill in the air, but still keeping an eye on the water in case breakfast swam by.

A little further up was a female Common Merganser floating on the water. And then I saw the Goldeneye ducks: mostly females, but several males, too.

Along with the Common Goldeneye (Bucephala clangula), I also caught sight of a Barrow’s Goldeneye (Bucephala islandica), distinguishable by the shape of the blotch on the face of the male. On the Common goldeneye, the blotch is round, and on the Barrow’s it’s like a paint-stroke. The Barrow’s also has “blocks” of white along the wing-line. We don’t get to see Barrow’s Goldeneyes around here much, so it’s always a treat when they show up. I was hoping the boys would do their flip-head dance for the girls, but they were all more interested in eating than in displaying. I got photos (and a little video) of all of them through the haze of the fog.

The other bird species I saw a lot of today were the European Starlings. In several spots, I saw them checking out nesting cavities in trees, going in and out, and talking to each other. I also saw quite a few California Scrub Jays, and one of them posed nicely for me on the humped back of a curved branch. In another park of the park,

I came across an area where smaller birds were trying to get to the last seeds on the now-dead star thistle: Spotted and California Towhees, Dark-Eyed Juncos, Golden-Crowned Sparrows and Lesser Goldfinches. What was surprising was that I didn’t see a lot of Acorn Woodpeckers or Canada Geese. They’re kind of ubiquitous, so to NOT see them is unusual.

Along my walk I also came across some Gouty Stem Galls, the leftover cocoon of a Tussock Moth caterpillar, the chrysalis of a Pipevine Swallowtail butterfly, and a few Deer Shield mushrooms. I walked for about 3 hours and then headed home .
