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.

Lots of Caterpillars along the American River, 05-25-19

I got around 6:00 am this morning and headed out to the American River Bend Park for my walk. It was overcast for most of the day, but I was able to do my walk without getting rained on, so that was good.

The first thing I saw when I got there was the leucistic female turkey and another “normal”-colored turkey walking through the tall grass along the side of the road with one small poult following after them. I don’t know which of the gals had the baby, but they both seemed to be taking care of it.  Poults are so hard to photograph most of the time because the moms try to keep them hidden as much as possible. So, I only got a few shots of the baby’s behind.

This is the time of year for caterpillars at the park and you could see Pipevine Swallowtail and Rusty Tussock Moth caterpillars almost everywhere you looked.  When I was videoing some of the Pipevine Swallowtail guys eating pipevine a woman and two of her friends came up. The woman plucked a caterpillar from the ground to show it to their friends, and when she came back to set it back onto a pipevine plant, I asked her if she’d seem the Tussocks.  She said, no, so I showed her where some of them were and gave her and her friends a mini lesson on the species.  Naturalist thing: check.

CLICK HERE for the album of photos.

The pipevine plants were abundant: on the ground, over logs, up into the trees and shrubbery. Some of them were super-thick.  The wild grape vines were also everywhere. They seem larger than I’ve seen them in years – but that’s because of the rains, I’m sure. We were living with drought with so long that we don’t recognize the landscapes with water anymore…  The Elegant Clarkia was in bloom all over the place; patches of pink – and some white – all along the river trail. So pretty.

Lots of House Wrens around singing today. I saw one male go over to a slit-like cavity in the side of a tree and look in, then he flew up into a nearby tree advertising his find.  But the cavity was already taken by a pair of Oak Titmice. The mom came up with a beak full of bugs and started fussing at the Wren. She flew at him a couple of times to drive him off, but he was pretty persistent. When both of them were away from the cavity, I walked up to the tree to see if I could hear any babies inside. When I tapped on the tree, I could hear a hiss from inside. Sometimes, baby birds hiss to make themselves sound like snakes, so predators won’t bother to come inside the nesting cavity – and it also deters human from trying to get a better look inside. Hah!

I walked for about 4 hours and then headed back home.

Lots of Springtime Insects, 04-20-19

I got up around 6:30 this morning and headed out to the American River Bend Park. It was overcast and in the 50’s when I went out, but by the time I got back home, around noon, the clouds were breaking up, and it was sunny and breezy for the rest of the day. Just lovely.

I wanted to see if I could find butterfly eggs at the park, and I was able to find some, but only on my way out. So, it was a long wait for the pay off, but I found a pipevine with several groupings of eggs on it. Actually, my photos turned into a kind of unintentional “study of pipevines” with pictures of the leaves, twining vines, seed pods, etc. It’s such a cool-looking plant.  In Victorian Era gardens it was all the rage; now people don’t plant it much anymore – and I think that’s partly because everything but the vines themselves die off each year, so it just looks “ropey” for half of the year.  It’s a boon to the Pipevine Swallowtail butterflies, though, who literally can’t live without it.

CLICK HERE for today’s photos.

While I was there, I saw a European Starling come out of her nesting cavity, so I waited by the tree to see if I could get a photo of her when she came back. Smart bird, though, she flew in behind me, making me turn as she went by, and went back into her cavity with an angry grumble.

I also saw some Wild Turkeys, including a leucistic female, and while I was watching them a bonded pair of Mallards came flying in and landed right near my feet. There was also a bonded pair of Common Mergansers on the bank of the river. These ducks are sometimes referred to as “Sawbills” because their bills have a serrated edge, which helps them hold onto the fish they catch. (They’re fish-eating diving ducks, as opposed to filter-feeding dabbling ducks like the Mallards.)

Saw lots of Craneflies (Mosquito Hawks) all over the place and Elder Moth caterpillars in the elderberry leaves. There were also a lot of Tussock Moth caterpillars, little nests of earwigs, some micromoths, and a mayfly that had just shed and was hanging next to its exuvia. This time of the year is soooooooooooooo interesting! I was surprised to see the earwigs snuggled in the tops of mugwort plants. I thought mugwort was a kind of natural insect repellent. I guess no one told the earwigs.

There were a lot of still-green Oak Apple galls in the trees, but I was really happy to come across some second-generation galls from the Live Oak Gall Wasp.  The first-generation galls are really obvious and visible: round balls covered in spines.  The second-generation galls are tiny and sit on the back of the leaves; they look like upside down volcanoes. Finding them is difficult, so I’m always excited when I get to see them.  The first generation of this wasp is comprised of all females that reproduce asexually, and the second generation is comprised of males and females that reproduce sexually. Cool, huh?

And while I was watching a male House Wren, I saw him look down below him. There was female down there with a feather in her beak. I’m assuming they had a nesting cavity near there somewhere and she was literally feathering her nest. Awwww!

I overdid it again today – because there’s so frigging much to see – and didn’t get back home until around 11:30. Four-and-a-half hours of walking; my body was really mad at me for the rest of the day.
