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.

Checking Out the Spider’s Den and Other Stuff, 05-18-19

I got up a little before 6 o’clock this morning and headed out to the Effie Yeaw Nature Preserve for a walk by myself.  I was trying to beat the rain – and was also on the lookout for slime molds.  I did beat the rain (it didn’t show up until around 3:00 pm), but I zeroed out on the slime molds. I think they need one more sunny day between the rainstorms to wake up.

It was nice and quiet on my walk, although I did come across a few other people. I was able to identify some birds to a couple who I think was visiting the place for the first time, and also directed a photographer to some good spots for photo opportunities. Doing my trail-walker thing.

CLICK HERE for the album of photos.

I saw a lot of the usual suspects: deer, turkeys, Starlings, House Wrens. I saw several bucks in their velvet, including the one with wonky antlers (one long and one short) and a torn ear. He should be easy to recognize from here on out.  And I also saw a doe with one ear that seemed really droopy. I don’t know what might have been bothering that ear; It didn’t look damaged or infected, at least as far I could tell.

A nice find was a male California Quail and one of his brides. I hear the quail at the preserve all the time, but they’re very fast and secretive, so I hardly ever get to actually see them.  This pair were pretty far away from me, across a meadow, but I was still able to get some shots. At one point, the male jumped up on a pile of brush so I could see him. They crack me up; their chubby little bodies look like light bulbs.

I also got to see quite a few female Common Mergansers going up into the cottonwood tree the Wood Ducks were in the last time. There were maybe three or four of the Mergansers, each flying around the tree and landing on different parts of it, quacking in low voices all the while. I don’t know if they were scouting out a nesting spot or were attracted to something else. I got some interesting-angle shots of them.

I was greeted by a pair of Western Bluebirds on another part of the trail. First the female flew in and then the male. They’re such bright, cheery-looking little birds. I always like seeing them.

And there was a very chubby California Ground Squirrel who popped up from her burrow to look around. I think she was pregnant based on her body mass. Their gestation lasts about a month, and then its another 6 to8 weeks before the babies emerge from the burrows. So, we won’t see them until sometime in July, most likely.

By the pond at the end of the Pond Trail were was some very fresh otter scat, so I’m guessing the otter was around there earlier this morning.  I’ve seen otters in that pond occasionally, but they usually wait until there are more crawdads around… The leeches in that pond might deter them, though.

I’m always curious when I find folded leaves or sealed leaf tents on plants, but I recognized what one was before I opened it when I found it on a mugwort plant. I handled it gingerly, and put it back where I found it afterwards.  Inside was, as I suspected, a mama American Yellow Sac Spider, Cheiracanthium inclusum, and her egg sac.

I was careful about how I opened it and handled it, because theses spider can pack a very painful bite (and are believed to bite more people than any other spider). The bite is said to burn like a wasp’s sting (and for sensitive people it can make them sick). The mother spider seals herself inside her rolled leaf tent with her egg mass, which can have as many as 100 eggs in it (although less is typical). She stays with the mass until the spiderlings hatch. After her babies hatch, she’ll stay with them until they’ve all gone through one molt (usually around 2 weeks).  As I mentioned, I set her and her tent back where I found them. She’ll spin new web to close her tent up again. ((Investigating leaf-rolls can be very interesting and rewarding for a naturalist, but just be careful.  You never know what might be inside of them.))

The young coyote showed up again today, in between two deer who didn’t seem to be aware that it was there.  It’s a very young coyote – gangly and thin, a teenager – but is hunting on its own, which I think is kind of unusual.  It moves too quickly, so I can’t tell if it’s a male or a female, but I did manage to get a few better photos of it today and a video snippet.

I got so preoccupied with my photo-taking that I lost track of time, and didn’t get back to the car until 11:30 am… So, I’d been on my feet for five hours. My ankles were killing me during the drive back to the house.
