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.

A Very Conspicuous Great-Tailed Grackle, 05-26-18

I got up at 5:00 today, even though it’s the weekend, because I wanted to get back to the Sacramento National Wildlife Refuge for a longer trip around the auto-tour there.  It was overcast and drizzling all morning, and the sun didn’t come out until just about when I was ready to leave the refuge.  I stopped off at the Colusa National Wildlife Refuge and spent about an hour there before heading onto the Sacramento refuge.

At the Colusa refuge, I was surprised to see a large flock of sheep near the front gate. Sheep and goats are often brought in to help clear the landscape of overgrowth and noxious weeds – because they eat anything. I saw several American Bitterns there, many of them on the ground among the tules. They were too far away to get really photos of them, but I managed to get a few so-so shots.

Most of the ground at the Colusa refuge are dry – no standing water – so it can be difficult to see much of anything.  I did get to see a lot of Great Egrets, Snowy Egrets and Great Blue Herons there, along with several crayfish chimneys, pheasants and a young Pied-Billed Grebe that was still sporting its striped face. The neatest sighting was that of a young coyote loping across the fields.

At the Sacramento refuge I was first inundated by sightings of Black-Tailed Jackrabbits, Desert Cottontails and California Ground Squirrels, and I thought that was all I was going to be able to see there today. Eventually, the place “opened up” to me and I was able to get photos of other critters, too. What was really nice was that I literally had the place all to myself. Didn’t see any other vehicles (besides the rangers’) until just before I was ready to leave. So, everything was nice and quiet, and I didn’t feel rushed.

CLICK HERE for the album of photos.

Of the ground squirrels, I saw, I came across one that exhibited a behavior I’d never seen before. It raised itself up on its hind legs, into a standing position, and then rubbed its head and face against a twig. I don’t know if it was transferring scent or just had an itch (it looked a bit mangy), but it was neat to see.

At one point, I stopped because I saw something “odd” on one side of a slough. I couldn’t get a good look at it, even with the telephoto it was sitting on the bank closest to the road, among the tules, with its back toward me. I kept an eye on it, and eventually it dipped down into the water in the slough… a muskrat! It played “keep away” for quite a while, ducking under the surface of the water just as I got the camera focused on it. After a while I tried to anticipate where it might show up next and was rewarded with some video footage of it. Phew!

The other cool find of the day was seeing a male Great Tailed Grackle walking along the rails of a wooden fence.  It was calling and posturing all along the way. I got some video footage (so you can hear the sounds it made) and some fairly good still shots… and I got to see some male Ring-Necked Pheasants sitting a tree. I’d never seen them in tree before; I usually sot them on the ground. They’re large colorful birds, so when they’re up in a tree they’re very “exposed”. There must’ve been something on the ground that scared them.

When I stopped to get some photos of a large bullfrog in the water, I saw something else beside it that I couldn’t identify at the time. I took photos and video of it and when I got home, I looked at it over and over again trying to figure out what I was looking at. I finally decided it was a pair of freshwater snails or whelks laying eggs on a rock… So weird…

I left the refuge around noon and was back home around 2:00 pm.

Mostly Wrens and Squirrels, 05-16-18

I was up around 6:00 am and took the dog with me over to the Sacramento National Wildlife Refuge. I encountered clouds along the way, but none of them amounted to anything where I was traveling. Back in Sacramento, however, they apparently got really organized and the city had rain, thunder and over 100 lightning strikes in the morning (just after I left). Wow!

At the refuge: because the big pond in the permanent wetland area is drained, there isn’t really a lot of anything to see there right now. Usually, there are frogs and snakes and all manner of birds around the pond, dragonflies and damselflies, a multitude of spiders, otters and muskrats…

Right now, the pond is like a PRAIRIE. Dried up with short vegetation sprouting throughout it and little mud holes here and there. It’s hard to get wetland wildlife photos when there’s no water! The geese were actually GRAZING where the pond should have been. *Sigh*

Still, I managed to get photos of some cottontails and California Ground Squirrels, and Marsh Wrens at their nests. I sat parked along the auto tour at one point for about 30 minutes, just watching a pair of the wrens. The male was out singing away, while the female flew beak-fulls of dried grass to the nest she’d chosen and arranged it inside. Once, while I watched, the male went up to the next and stuck his head, checking out the female’s work. When she came back with a mouth full of twiglets, he flew off singing again. The opening to the nest was turned away from the car, so I couldn’t see in to see what she was doing. Danged smart little birds.

The California Ground Squirrels seemed to be everywhere. They should have lots of babies to feed this time of year. As an aside, did you know that in 1918 California launched a campaign to eradicate these native squirrels and even had posters and pamphlets printed encouraging children to join the “army against the squirrels”? “Children, we must kill the squirrels to save food,” a woman on the pamphlet says as she’s smiling. “But use poisons carefully.” The pamphlet included a recipe for strychnine-laced grain as well as suggestions for other extermination methods, such as shooting, drowning, and poison gas. Horrifying (and stupid). The campaign, sanctioned by the state government, actually came from the beef industry which claimed the squirrels were eating all of the grain on which the cattle fed.

I also came across a large creche of Canada Geese (parents, fuzzy goslings and fledglings); about 30 babies altogether(!). This is typical for Canada Geese. One set of adults watches over the group while the other parents feed, and the babies are kept in a group with the youngest in the center and the older ones on the outside. The behavior provides safety in numbers, and also teaches the young ones the concepts of following the leaders and working together – which they’ll need during migration.

In different spots along the route, I was able get good photos of a Red-Eared Slider Turtle and a large Pacific Pond Turtle, so that was nice. For all of my “bitching” about the lack of the big ponds, I did manage to see and count about 43 different species (plants and animals), so the trip wasn’t a waste… And it got me outside, into the fresh air, and focused on something other than my grief over the death of my brother Michael and his wife Sharyi…

On my way out of the refuge, I found a pair of Mourning Doves sitting in a tree, a male and female cooing at each other. They immediately brought Mike and Sharyi to mind, and even as lovely as they were, they brought a tear to my eye…

When I got back to the house it was around 2:00 pm. After a late lunch, I walked around the yard with the dogs and took photos of stuff like the Yellow-Billed Magpies in distant trees, a very fat American Robin (it made me chuckle, it was soooo chubby), and the Genista Broom Moth caterpillars that are currently multitudinous on the broom plant in the corner of the yard. They’re generally yellow-orange caterpillars with clusters of black and white spots on them and long sparse white hairs poking out all over. When the light hits them just right, they look like tubes of orange glass…

When mama moth lays her eggs on the plant, she lays them in clusters, one row overlapping the other, like fish scales. The caterpillars only eat broom, so they’re not a danger to the other plants in the yard. They’re also able to “jump” from one branch to another to escape predators.
