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.

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.

A Western Tanager and Others, 04-30-17

I got up around 6:15 and was out the door by 6:30 to head over to the American River Bend Park for a walk.  It got up to 82º today.

At the River bend Park, the elderberry bushes are getting their flowers on them, and the buds on the Buckeye trees are just starting to open. Pipevines, grape vines and manroot vines abound, many of them vying for the same spots in the sun; and the black walnut trees are heavy with catkins. I was hoping to get some photos of Pipevine Swallowtail butterfly eggs, and was a little surprised to find that the caterpillars had already hatched out of most of them!  There were little first and second instar caterpillars everywhere…

CLICK HERE TO SEE THE ENTIRE ALBUM. More videos will be added shortly.

I also got to see a few Tussock Moth caterpillars, which are always cool. I even got one to crawl on my hand for a little while… (They’re the moths in which the female is wingless.  She sit in the tree she was born in and waits for the males to come to her.)

And I also came across an area where a bunch of Elder Moth caterpillars (a kind of cutworm) were coiled up on young elderberry bushes; some had curled themselves into the leaves, and one leaf curl had a shiny new pupa case in it… Neato.  [The Elder Moths are white and super-fuzzy and have green “staining” on their wings.]

A couple of other cool things happened on this walk, as well.  The most exciting was when I was trying to get photos of a pair of Bewick’s Wrens that were bringing food to their hatchlings.  The wrens were nesting in a tree cavity BUT, the tree was lying on its side on the ground, so they had to go through grass to get to the opening.  I was trying to figure out how to shoot through the grass and eliminate the heavy shadows around the opening to the nest, when I heard screeching in a tree behind me. I turned around to find a handsome Cooper’s Hawk up in the tree… and as soon as I looked at it, it started buzz-bombing me.  It dove straight at my head, so I lifted my camera up to deflect it.  Then it landed up in another tree, and I was taking photos of it there, it dove at me again… and again… and again… first from one direction, then from another. I don’t know if I was too close to its nest, or if it had a fledgling on the ground, or if I was too close to its breakfast, but it was NOT happy.

I got as many photos of it as I dared, and then walked off before it had the chance to gouge out my eyes.  (I tried getting video of it. I got a few frames of it screaming and diving at my head, and then the rest of the video is just a bunch rapid shaking and me shouting in exclamation.  I might add that to the album just because it’s funny.

I never did get a photo of that wren’s nesting site; maybe next time. But I did get some video of wrens singing and “beeping”, so that was something of a consolation.

Another cool thing: I saw some European Starlings picking stuff off the side of a tree, so I went over to see what so interesting to them.  A huge portion of the tree was literally covered in ants; a whole bivouac of them including some winged ones. I don’t know if they were moving in or moving out, but there were hundreds of them.  While I was getting some video of that, I noticed something “yellow” in the periphery of my vision, so I looked up and… Wow, it was a gorgeous Western Tanager! I’d never seen one at the park before.  It grabbed some of the winged ants and flew off, and then came back and sat on the low branch of a nearby tree for quite a while. In order to get pictures of it, I had to shoot through the leaves of the tree closest to me, a little hole about the size of my fist, and then get the camera to focus on the bird and not the leafy edges of the hole.  I got quite a few good photos, including a cute one of the bird cocking its head to one side. I was super-pleased.

Aaaannnd… I also got to see an Ash-Throated Flycatcher. He was sitting on the top of a small, broken, dead  tree trunk, but his back was to me so, all I could see with this powderpuff of feathers on the top of his head.  Then the bird flew off into another branch, and I could see its whole body… Yep, Flycatcher.  They’re not uncommon birds, but I think I’ve only seen maybe three or four altogether at the River Bend Park.

On the way out of the park, I walked by a spot where a couple of Tree Swallows were making all sorts of noise. That always alerts me to the notion that there’s a nest nearby, and sure enough, I was able to spot it as one of the birds exited the cavity.  I had to climb over a (very low) fence and then find a position where I could view the tree without interfering with the birds and watched it for about 10 or 15 minutes. I got quite a few photos of the birds in and near the nest hole… and even watched as one of them chased off an interloper when it got too close. That was a nice way to end the walk.  (I actually walked for a little more than 3½ hours before heading home.)
