Dr. Seuss-Like Seed Heads at Folsom Lake!, 05-31-23

Leave a comment

I was up around 6:00 AM so I could feed and potty my dog, Esteban, and then get myself ready to head out to Rocklin and Johnson-Springview Park with my friend and fellow naturalist, Roxanne. We were looking for springtime galls.

There aren’t a whole lot of spring galls (most of the galls appear in the summer months), so the pickings were kind of slim. We did find a few, however, including a few Hair Stalk Galls, a Fimbriate Gall, the bisexual spring generation gall of the Stripe Volcano Wasp, and Oak Apples in the BLUE oak trees. Yes, in blue oaks; you usually only see them on Valley Oak trees. But the Blue Oaks and the Valley Oaks are both in the white oak lineage, so there can be crossover between those trees. Here’s how those lineages look on the oaks native to California:

The Blue and Valley Oaks in this park also grow very close to one another, and some, I’m sure have been hybridized.

We saw a few, but not very many, insects, and I’m going to raise the alarm again about the fact that we’re losing insect species every year; even I can see that.

“…The world has lost 5% to 10% of all insect species in the last 150 years — or between 250,000 and 500,000 species, according to a February 2020 study in the journal Biological Conservation. Those losses are continuing, though estimates vary due to patchy data as well as uncertainty over how many insects exist…One April 2020 analysis in the journal Science suggested the planet is losing about 9% of its land-dwelling insect population each decade. Another January 2021 paper tried to paint a clearer picture by synthesizing more than 80 insect studies and found that insect abundance is declining around 1% to2% per year. For comparison, the human population is growing at slightly less than 1% per year…The demise of insects can’t be attributed to any single cause. Populations are facing simultaneous threats, from habitat loss and industrial farming to climate change. Nitrogen overloading from sewage and fertilizers has turned wetlands into dead zones; artificial light is flooding out nighttime skies; and the growth of urban areas has led to concrete sprawl…” –The Collapse of Insects

Among the insects we did see were aphids, Mirid bugs, a lacewing larva (commonly called an “aphid lion”), and ladybeetles. We found one lady beetle that had just emerged from its pupal case and was sitting on top of it while it “colored up”. Closer inspection of the pupal cases showed two silk threads anchoring the cases to their leaves. I had never seen that before. I wonder if it’s truly unusual or maybe species-specific.

At the park we also saw a few bird species including House Sparrows, Robins, Yellow-Billed Magpies, Scrub Jays, Lesser Gold Finches and House Finches, a few Killdeer, and Acorn Woodpeckers. One of the magpies was harassing a Fox Squirrel that was in IT’S tree. So much noise! The Goldfinches were eat seeds among a stand of thistles and oat grass.

There were stands of Harvest Brodiaea among the tall grasses on the ground. That was a little bit of a surprise as neither Roxanne nor I could remember seeing them in the park before. There was also more color in the small citizens’ garden there: snapdragons, sunflowers, sweet peas, marigolds, garlic and artichoke thistles.

On our way out of the park we got to see a California Ground Squirrel among the rocks. There was another ground squirrel giving off a loud and piercing alarm call. Here’s a 2019 video I took of a ground squirrel giving off that call.

After we were done in the park — having seen just about all we were going to see there today — we made a plan to go to brunch and then head off toward Folsom to see what we could see there. We decided to go to the Granite Rock Grill, one of our favorite haunts, for brunch. Their servings are always large, and the food is flavorful. What’s not to like?

Then we headed over to the Folsom Lake State Recreational Area and drove a few miles around the perimeter of the lake. The lake is actually a man-made reservoir, and is currently at about 85% capacity thanks to the intense winter rains and the current snow-melt.

I had actually never been to the lake myself, so it was all new to me. I was surprised by how many wildflowers were still in bloom around it. There were huge swaths of bright pink Elegant Clarkia, and Tiling’s and Bush Monkeyflowers, in some areas as far as the eye could see, That was true of the blooming Buckeye trees, too. They were all over the place.

We also found young Wild Carrots, Mule’s Ears, Spider Lupine, some Willowherbs, Rabbitfoot Clover, flowering Coffeeberry, Madia, and Harvest Brodiaea, and others.

Among some of the Harvest Brodiaea, we found several of them with galls in their stems. We’d seen old, dried out versions of these at Sailor Bar on the American River and thought they were associated with Ithuriel’s Spears. It didn’t occur to me that they were in the Harvest Brodiaea. The galls are caused by midges.

Another sweet find was seeing a collection of pink Twining Snakelilies along the side of the road winding their way through grasses and over fallen trees. And around the same area, the Pipestem Clematis was going into its seed form with Dr. Seuss-like heads on long tendrils. The clematis “… can climb to 20 feet and can take light shade or full sun…”

Beyond a single Great Egret, some Turkey Vultures, and some Canada Geese we really didn’t see much in the way of bird life. As far as I could tell from the views of the lake I got, the lake was pretty much devoid of water fowl.

Altogether, we saw a lot more than I thought we might! This was hike #31 of my #52hikechallenge for the year.

Low to No Water at the SNWR, 05-26-23

Leave a comment

I got up around 5:30 this morning, so I could get the dog and myself ready to make the long drive to the Sacramento National Wildlife Refuge (SNWR). It takes about 2 hours to get there from the house. We stopped to top off the gas tank and get some coffee, and were on the road in earnest by 6:00 AM.

With the place nearly devoid of any standing water, it was more like a late-spring grassland than a wetland area.

There was a little water near the turnouts on the auto route, but not a lot. And I didn’t see any waterfowl in those areas.

Even the large “permanent wetland” pool was just barely full of water. It looked like it was maybe only a few inches deep, and when the coots and grebes swam through it, their knobby knees came up over the surface of the water.

This pond had recently been reformed, and along a large swath of the bank all of the vegetation had been completely removed. I didn’t understand that. The place is supposed to be a “refuge” for wildlife, but removing the vegetation meant the little Marsh Wrens wouldn’t be able to build their nests there, dragonflies and damselflies wouldn’t be able to emerge there, and the summer spiders wouldn’t have anywhere to build their webs.

The lack of vegetation does mean you have a much better view of the water. But with the lack of waterfowl at the moment and the shallow depths of the pool, there wasn’t much to see anyway. I also noticed that some of the “islands” that had stood in the pond previously, were now gone. That was upsetting because traditionally, cormorants and White Pelicans used to rest on those islands.

I DID get to see some of the usual suspects like the Coots, Canada Geese, the last of the migrating Snow Geese, Killdeer, Lesser Goldfinches, Meadowlarks and Mallards. In some places along the auto tour route, the Killdeer ran in front of the car, sometimes laying down in their “broken wing” displays — which meant they had nests on the ground around there. I drove really slowly, worrying all the while that I was inadvertently crushing the nests and their eggs hidden in the gravel. Yikes!

In the water of the permanent pool were a few Clark’s and Western grebes floating about, but none of them seemed to be paired up yet. There were also a few Pied-Billed grebes. One of them was hoot-calling to its mate; such a cool sound. I also got a little footage of a Black-Necked Stilt complaining about something. They’re so loud!

There was also a pod of Ruddy Ducks, males and females, and most of the males were in their breeding plumage, bright blue bills and everything.

I saw a couple of the males doing their courtship displays, which are really kind of hilarious. The males swim in front of the females with their tails and eyebrows raise high, then they thrum against their chests with their bills, making bubbles appear in front of them. Hah!

“…They punctuate the end of the display with a belch-like call,,, Everything about this bird is interesting to the naturalist, but almost nothing about it is interesting to the sportsman…” –– Cornell

I got a tiny bit of video of the behavior, but the birds were pretty far away, and sometimes had their back to me.

I had better luck getting some video and photos of the male Marsh Wrens, including one that was standing next to one of the nests it had built.

Along another part of the pond, there was nothing but Bird’s-Foot Trefoil on the bank. And in other areas there was Poison Hemlock, Blessed Milk Thistle, and teasel in various levels of blossoming. I also saw some Brass Buttons, Downingia, Spikeweed, Cocklebur, Smartweeds, and Dock. The Yellow Star-Thistle was just starting to emerge.

One of the things that surprised me was seeing a few different forms of witches broom on the mustard plants. The wild growth is caused by a kind of phytoplasma.

“…Phytoplasmas are obligate intracellular parasites of plant phloem tissue and of the insect vectors that are involved in their plant-to-plant transmission. Phytoplasmas were discovered in 1967 by Japanese scientists who termed them mycoplasma-like organisms…” — Wikipedia

“…Dr. Saskia Hogenhout, a scientist at the John Innes Centre in England, and her colleagues reveal that some of these creepy alterations are driven by the work of a single protein from the parasite called SAP05, which stands in the way of the plant’s maturation…In the new paper, they explain how SAP05 seems to drive some of the more surprising effects, like the life-span extension. ‘It looks like it stays in a juvenile phase,’ [she] said…” — The Indian Express

I didn’t see any evidence of the large orb-weaver spiders that usually inhabit the pond area in the summer, and I only found a few damselflies and dragonflies. Among the dragons, I only found male and female Variegated Meadowhawks. It’s still early in the season, though. A kind of Deer Fly with “crazy eyes” came into the car for a short period of time. I also saw some Sulphur and Cabbage White butterflies flitting around, but I was only able to get photos of a cooperative West Coast Lady butterfly.

As I left the pond area and headed toward the viewing platforms, I saw some Cliff Swallows darting back and forth, into and through a drainage block. [I assume they were building nests in there, and/or feeding nestlings.] Some of the fledglings sat among the tules, waiting for their parents to feed them.

Other critters I saw today were quite a few jackrabbits, a pond turtle, some Western Fence Lizards, and a California Ground Squirrel grooming itself.

Because I was in my vehicle for the majority of this trip, I didn’t count it toward my #52hikechallenge for the year.

The Pipevine Swallowtail Caterpillars are Abundant at the River Bend Park, 05-24-23

Leave a comment

I felt really good after doing the chores I did yesterday, and was looking forward to doing some exercise today with a walk at the American River Bend Park. Third or fourth visit there over the last month or so, but I always see something different every time I go there. It was a gorgeous morning, 51ºF, clear, sunny, and breezy.

The American River was still way up. Water covered most of the bank areas and swamped the trees. Some of the trails that led down to the bank, now led right to the water. According to the Department of Water Resources, releases from the Nimbus Dam are currently at 15,000 CFS. That’s up from 7,521 CFS just last month. Wow.

The first thing I saw when I drove into the park was a young buck in his velvet grazing along the side of the road. I later saw a couple more deer near the equestrian area. I also saw a few Black-Tailed Jackrabbits, Fox Squirrels and California Ground Squirrels. I was hoping to come across a coyote (as there were signs all over the park stating there is an active den in the park), but… no such luck.

I didn’t see a lot of birds, although I could hear them singing and moving through the trees overhead. I did see some Black Phoebes, and watched as a House Wren brought bright green caterpillars to her fledglings for breakfast. They’re such cute little birds. I also found an old hummingbird nest held to the forked branches of an oak tree with spider webs.

The river was running so fast, I only saw two waterfowl braving the current: a male Mallard and a female Common Merganser. Across the river in the the high naked branches of a tree were several Turkey Vultures sunning themselves.

The big news for me today was: I saw lots and lots of Pipevine Swallowtail caterpillars ,in various instars, almost everywhere I looked. Although some had climbed up into the tall grass and Mugwort plants to warm themselves in the sunlight, I didn’t see any of them making themselves ready to form their chrysalises. CLICK HERE to see a video of the butterfly’s lifecycle.

I saw some of the butterflies flitting about, and was also able to catch a well-worn female to get some close-up photos of her. Her wings were ragged from dealing with males, winds, and the razor-edges of the grasses. As battered as she was, she was still very much a fighter. I took a few photos of her and released her back onto a pipevine plant.
