At the Sacramento and Colusa Wildlife Refuges, 05-06-19

Certified California Naturalist, Roxanne Moger and I went out to the Sacramento National Wildlife Refuge around 6:00 am this morning. The weather was beautiful today, but there wasn’t a lot to see at the preserve. We’re kind of in between seasons, so the large flocks of birds have all left, but the insects (like dragonflies, damselflies, and orb-weaver spiders) haven’t arrived yet. We did see swarms of Painted Lady butterflies and some Cabbage White, but none of the other species normally seen there in the late spring/early summer.

Roxanne did all the driving, but we stopped a couple of time to get out of the car and walk parts of the trail or explore the boundaries of the park-and-stretch areas. Some of the vernal pools on the site were in bloom: all golden yellow and purple with Goldfields and Downingia. Just beautiful.

Although the species list at the end of the day wasn’t as long or as varied as I’d like, I did like the fact that I saw a few things I’d never seen before and learned more about some species than I’d known before. That’s what really makes these outings fun.

A large fly landed on the passenger side mirror of the car partway through the auto-tour and at first I thought it was a Robber Fly (those guys are pretty big). We were both intrigued by the fly’s huge goggle-like eyes and his tenaciousness.  He held onto that mirror for quite a long time.

When I got home, I looked up the fly to see if I could find its scientific name and found that it was actually a male Striped (or Lined) Horsefly, Tabanus lineola. I’d never seen one before. And, of course, once I find something new to me, I have to research it more.  Never having encountered a Horsefly before, I was surprised to learn that although the males drink nectar, the females drink blood (usually from large mammals like livestock). She had scissor-like mouth parts that slice into the skin so she can get to the blood. This species is usually found along the east coast and Gulf of Mexico, so it was something of a surprise to find it here… assuming I got the ID correct.

We also got to see a male Red-Winged Blackbird flaring his epaulets at a female, and a pair of Brown-Headed Cowbirds performing what we thought was courtship behavior.  The two birds sat across from one another, then one ruffled its feathers, opened its wings a bit and bowed down at the other, and the other responded in kind.

Roxanne and I inferred the behavior was “courtship” but, from what I read, after I got home, what we were seeing was actually two males trying to outdo one another in a machismo contest.  Apparently, the females don’t respond well to the males’ bows, which they see as aggressive, so the males only bow to one another. (You can read more here.)  The males open their wings to one another, and to females, to show how mature they are. Juveniles have pale markings on the inside of the wings.

You can see the video snippet I took of the birds HERE.

And we found a couple of Black Phoebe nests, one stuffed full of babies who were almost fully fledged. They were stacked up, one on top of the other, with their tails sticking out over the edge of the nest. And toward the end of the auto tour route we came across a dead tree where there was a Western Meadowlark, a Red-Winged Blackbird and a tiny Song Sparrow all singing their respective songs.

We caught glimpses of American Goldfinches and Bullock’s Orioles, and hear Bitterns, but didn’t see any. One oddity was sighting a Mute Swan in the permanent wetlands area. That was odd because swans hardly ever go into the refuge, and Mute Swans are actually an invasive species. Unlike the Tundra Swans, the Mute Swans are super-aggressive and destroy the habitat they live in by ripping up water-plants from the roots.

When we were done at the Sacramento refuge, we decided to go over to the Colusa National Wildlife Refuge to show Roxanne the day-roost of the Black-Crowned Night Herons at the end of the auto-tour there. We were astonished to discover that the auto-tour there was roped off so no one could get to it… but the rope and signage was only visible AFTER you entered the refuge and started driving down the route. Stupid. They should have put the signs on the front gate or in the parking area.  A “manager” who showed up a little while after did, said that the auto-route was shut down because they were short handed and couldn’t patrol it well enough. Sad.

So, we didn’t do that tour and instead walked around a little bit in the native flower garden they have near the restroom facility.  Along part of a path near the garden, Roxanne found some galls we’d never seen before: the gall of the Elm Balloon-Gall Aphid, Eriosoma lanuginosum.

According to what I’ve read, the galls are initiated by a “fundatrix”, a parthenogenetic female aphid whose presence causes an extreme enlargement of the soft cell tissue on one side of the leaf. The galls are hollow and feel rubbery. They start out green and are covered with fine white hairs (which we saw) and turn brown as they age.

Inside the gall the fundatrix has her babies which are wingless and yellow until they mature. There can also be second generation aphids, called “alates” (usually winged individuals) which are dark green to black and wax powdered. Not all of the adults grow wings, however, and wing-growth seemed to be associated to crowding inside the galls, a short supply of food, and/or changes in the environment. Nature is so cool!

After walking around a bit, we headed back home to Sacramento and got there around 3:00 pm.

It was “Buggy” Out There Today, 04-27-19

I got up a little before 6:00 am and headed out to the Effie Yeaw Nature Preserve for a walk.  I wanted to get there by 6:30 so I could beat the heat for today.  Actually, the weather was rather pleasant all day, but anything over 70° is uncomfortable for me when I’m outside.

When I got there, The-Other-Mary, Mary Messenger, another volunteer trail-walker at Effie Yeaw, was there wanting to join me, and my friend/naturalist/volunteer Roxanne Moger also showed up. So, we had a nice time looking at all the little stuff that was around us.

CLICK HERE for the full album of photos.

Roxanne and I were more focused on bugs and galls this time around than the larger animals, so we were moving really slowly, investigating the leaves of plants and using the macro-settings on our cameras.  I actually like the quality of the macro-photos better on my cell phone than on my camera (it can get in tighter and more clearly), so I was using that a lot.  The best finds of the day were made by Roxanne who discovered a Tiger Swallowtail butterfly in a tree and a California Alligator Lizard hiding in some clover.  The alligator lizards are super-common in Southern California, but we don’t see them much here, so finding one is always fun.

We located a Black Phoebe nest, found out where an Oak titmouse was hiding out in a tree (that was guarded at the moment we saw it by a Western Fence Lizard), and also saw a Starling leave her nesting cavity with a white glob in her beak. She threw the glob down in a field and kept on flying.  I’m assuming she was doing housekeeping and tossed the babies’ fecal sacs.

We saw a few deer, including a pair of bucks in their velvet. One of the bucks decided to do a head-scratching maneuver that, at the same time, flashed his junk at us.  Hah!  How rude!  I also came across a doe who was having a sneezing fit.  I don’t know if she snuffled up something while she was browsing or what, but she was loud!

The elderberry bushes are just starting to flower-out, as are the Buckeye chestnut trees. The few plum trees in the preserve already have plums on them, and some were starting to turn purple.

On the walk, we came across both Oak Apple wasp galls and Live Oak wasp galls.  And, as for the insects, I saw Pipevine Swallowtail caterpillars and butterflies, Painted Lady caterpillars and butterflies, some Tussock Moth caterpillars, Craneflies, some bumble bees, hover flies, damselflies (including a male and female Pacific Forktail), Soldier Beetles, ladybugs, aphids and some Spittle Bug spit and other critters. There are so many teeny-tinies around.

By this time of the spring, some of the butterflies are already looking pretty ragged. I saw several of them with tears in their wings and frayed edges.  I think some of the damage is done by the grasses that grow up around the flowers and plants the butterflies utilize. The razor-edges of the grass can cut human skin, so I can only imagine how quickly they can damage the fragile wings of the butterflies.

I walked for about 4 hours and then headed home.

Escaping from the Zantis at the Sacto Refuge, 04-03-18

The dog and I got up at 6:30 am and headed out to the Sacramento National Wildlife Refuge to get a nature fix and to escape the “Zantis” (termite inspectors) coming to the house today.  It was 49º when I left the house, and got up to 80º by the late afternoon.  It’s too early in the year for 80-degree-weather!

CLICK HERE to see the album of photos and video snippets.

On the way to the refuge, along the highway, I saw the carcasses of a red fox (!) and a raccoon. I always kind of punch myself when I see road kill. I have permits to pick up the carcasses if I want to so I can use them for the naturalist class – but I always forget to bring a copy of the permits with me. D’oh! The skulls would have been awesome…

At the preserve, I got to see a raccoon (stepping gingerly through the low water) but no foxes. I think the last time I saw a live fox was at the Shasta house. I HEARD some at Lake Berryessa last year, but I didn’t see them…

When I first drove into the preserve, before I even got to the kiosk, I saw a group of Turkey Vultures sitting on the railroad tracks. I couldn’t see if they’d found something to eat or not, but they all took off as soon as they realized I’d stopped to photograph them.  I came across another pair of Turkey Vultures further along the auto tour route. They were sitting near the ground on a stump, but once again, as soon as I approached to take photos, they took off.  What was really freaky was that a few seconds after the vultures left and Red-Tailed Hawk burst out through the tall greenery around the stump! The only thing I can think of was that the hawks chased something down and killed it, and when the vultures moved in to try to steal the meal, the hawk pushed it further into the shrubbery…

Along the auto tour route, I could hear the “pumper-lunk” call of Bitterns, but wasn’t able to see any of them. I could also hear  Great Tailed grackle singing his variety of songs, and looked all over for him. I finally found him in a tree, and got some video of him, but he was obscured by branches. So you can see him very well, but you CAN hear him.
