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.

Standouts: a Lorquin’s Admiral and a Wilson’s Snipe, 11-03-18

I left the house with the dog around 5:30 am to head out to the Sacramento and Colusa National Wildlife Refuges. It was already 62º there and was windy; not a strong blow-you-over wind, but strong enough so that it kept a lot of the birds hunkered down to keep warm. Neither refuge is at full water capacity yet, so there were long areas of nothing but dried grass and tules. In another month or so, viewing should better.

At the Sacramento National Wildlife Refuge, the first thing I saw was a Black-Tailed Jackrabbit using a stand of tules as a windbreak. I saw several Red-Tailed Hawks in the trees, saw some American Kestrels on the wing, saw a Northern Harrier on the ground, and lots of Turkey Vultures surfing the wind currents. One of the Red-Tails was so huge, I thought at first that it might be an eagle; the female Red-Tails can get REALLY large. I also heard but didn’t see a Red-Shouldered Hawk.

Lots of Song, Savannah and White-Crowned Sparrows were out along with huge flocks of Snow Geese, Greater White-Fronted Geese, and Northern Pintail ducks. I also saw several Ross’s Geese – which look like Snow Geese, but they’re smaller and don’t have the black “grin patch” on the beak. Among the other ducks were Northern Shovelers (some still in their eclipse plumage), American Wigeons and Gadwalls. The Pintails always out-number the other ducks this early in the season as they’re the first to arrive.

Some areas along the auto-tour route were laden with the thick sticky webbing spiderlings use to “balloon” along the landscape. Long strands and bunches of “spider snot” seemed to be everywhere.

Two standouts at the Sacramento refuge were a Loggerhead Shrike and a Lorquin’s Admiral butterfly. The Shrike had posted itself on some dead cattail stems and as I watched it impaled a large insect on a shard along the side of the stem. Then it manipulated the insect a little bit with its beaks and feet before eating it. I think the insect was a big grasshopper, but I couldn’t get a really good look at it. Shrikes are referred to as “butcher birds” and “songbirds with the heart of a raptor” for their hunting and butchering behaviors.

The Lorquin’s Admiral was a huge surprise. It’s very late in the season for them to be out. This is a kind of butterfly that has several “flights” throughout the year, and they feed on nectar from California Buckeye trees, but they also like bird feces. Ugh. No accounting for taste! What’s cool about these guys is that even though they’re basically made out of “fuzzy air”, they’re super-aggressive and will fight protect their territory. Sort of like getting sucker-punches by a paper doll. Hah! The caterpillars roll themselves up in the leaves of willow trees (among others) and overwinter in them.

At the Colusa National Wildlife Refuge, I saw a lot of the same birds that I did at the Sacramento refuge, but the standout was a Wilson’s snipe and flew up right next to the car and walked around the muddy ground there. Every once in a while, the bird would tilt its head to look up at me as I frantically snapped photos of it through the driver’s side window of my car.

On our way out of the auto-tour route at this refuge, I saw a pair of young Columbian Black-Tailed Deer grazing on the berm that was covered with geese and ducks. The deer didn’t seem to mind it when I stopped my car next to the end of the berm to take some photos and video of them, but when another car came up behind mine, they startled. I was surprised when, instead of running away up the berm through the flock of birds, both deer came charging down the berm right toward my car. I was afraid they were going to hit it. But they both veered off, one after the other, and crossed the auto-tour route road in front of my car – kind of using my car as a shield – before they jumped into the trees and overgrowth on the opposite side of the road. Wow. Got my heart going for a little bit. I don’t know what it was about the other car that made them so afraid.

When I was done with the auto-tour route, I parked near the restroom facility and then took Sergeant Margie out on his leash to stretch his legs. ((Dogs are allowed on the preserve, as long as they’re in your car or on a leash.)) I started down the trail that runs along between a large wetland area and a slough (so you have water on both sides) and was happily surprised to see that Sergeant Margie was able to handle walking a half mile in and a half mile back to the car (one mile round trip). He hasn’t been able or willing to do any kind of “long” walk for almost a year.

I think it helped that the temperature outside was comfortable and the trail was flat and covered with soft leaves. His tongue was hanging out when we got back to the car, but he wasn’t coughing or complaining. I gave him some lunch and a big drink of water before we headed back home.

Lots of Surprises at the Refuge Today, 05-23-18

I went out looking for field trip sites for the naturalist class.  I timed the trip(s) from Woodland, not the house in Sacramento, and to Anderson Marsh it takes a little over 90 minutes.  To Clear Lake State Park it’s another 30-45 minutes. (I just went past the main gate and didn’t go in.)  – and then finding somewhere to park and finding the trail heads might take up another 30 minutes.  That’s just too much time in the car and not enough time walking.  If we had a campout there it might be doable, but otherwise, no.

Anderson Marsh might be an option, but still, it might be easier on folks if we did an overnight in Williams and tackled the marsh from there. (It’s up Highway 20, to Highway 53.) I want to make that run one more time to see if it’s really feasible.  The crappy thing is: I wanted to go out onto the trails at the marsh, but although they let dogs in the parking lot, they don’t allow them on the trails. I wasn’t leaving Sergeant Margie alone while I did some walking.  I should have checked that before I brought him with me.

So, I felt like the first part of my morning was kind of a bust. There are caves and a geothermal plant up there, too, but I didn’t go to check them out. Instead, I turned the car around and headed back to Williams.

Since, I was already in the area, I went over to the Sacramento National Wildlife Refuge and made a quick run through the auto-tour there. I was MUCH more successful there than I was in Lake County. The drive seemed full of surprises.

At one point along the auto tour route, I saw a pair of Killdeer along the side of the road.  Mama started doing her “broken wing” act, so I knew there must have been a nest near the road somewhere. (Killdeer like to nest in gravel, and their eggs look like little speckled rocks.) The surprise was, though, when I saw a tiny, fuzzy Killdeer baby running across the road! They’re so small, it’s hard to see them unless they’re moving. It crouched down in the gravel in the middle of the road, and I was soooo worried that I might accidentally run it over, so I very slowly pulled the car off to the side of the road (still worrying that a nest might be there.)  The baby ran around and stomped its tiny feet on the ground, peeping for mom.  Mama finally showed up, peeping loudly, and had the baby follow her back to the nest (behind my car and down the road a little way.)

Surprise #2 was seeing eagle at the preserve. They’re usually gone by March, so seeing them in May was completely unexpected. I saw an adult and what I thought was a juvenile Bald Eagle picking at a Snow Goose carcass. The juvenile eagle flew across the now-empty large pond (on the extension loop) and landed in a tree right along the side of the road – so I was able to get some photos of him. As I looked over the photos, it struck me that this wasn’t a juvenile Bald Eagle at all; it was a young Golden Eagle. The giveaway was the feathering that went all the way down its legs to its feet.  Cool!  I’d never seen a Golden Eagle out there before.

Surprise #3 was a muskrat. I saw something moving in the water in a slough along the side of the road, and it was at a distance, so I wasn’t sure what I was seeing. I videod it before it disappeared under the surface of the water. At first, I thought it had been a Pied-Billed Grebe floating low through the water, but when I took a closer look at the footage, I found it was a muskrat, swimming with its nose above the surface.  I think I also located where the entrance to its push-up was, so I’ll check that out the next time I’m there.

Surprise #4 was seeing a gorgeous Valley Garter Snake sitting the shore next to the water, warming itself in the sun. Usually, the snakes zip away and all I get is a photo of their side or the end of their tail as they disappear into the water or the brush. This snake sat still, and I was able to get a lot of pictures of it, even its face.

Surprise #5 was seeing a fawn that looked like it was “right out of the box”, maybe only a day or two old. It was very small – but bounding, jumping and curious – and still had its newborn blue eyes.  It was following after its mom who was walking through a stand of cocklebur. The baby was so little, he’d disappear under the big leaves of the cocklebur, then appear again a few feet away.

Surprise #6 was a California Ground Squirrel that ran out near the side of the road with a huge Milk Thistle flower-head in its mouth. I stopped the car and watched as the squirrel held onto the head, ripped through the back it, to avoid the spines on it, and pulled out all of the seeds.  It struck me as funny: it looked like a bridesmaid who had caught the bouquet and then ATE it. Hah!

I saw several American Bitterns flying overhead but none on the ground, a hawk flying off with its kill (with a Crow chasing it), a fledgling Northern Harrier sitting on the ground with whatever it had been able to catch, and Marsh Wrens singing (and one building a new nest). I also caught a glimpse of Orioles and got some good shots of a Blue-Winged Teal, among other critters.  It was a nice way to end the day.
