Lots of Snowy Egrets, 05-31-19

I got up about 5:30 this morning, fed the dog his breakfast and then headed out to the Cosumnes River Preserve for a walk.

There was little to no water in the “wetland” areas, so not a lot of birds or dragonflies. I walked along the slough on the side of the road, and then walked through the oak woodland to the nature center, and then back to the car.  Along the slough, I saw Tree Swallows, a pair of Western Kingbirds, and a trio of Brown-Headed Cowbirds doing their bowing thing. They were on the top of a tree, so bowing was difficult, and they kept rolling off their twiggy branches. Eventually, they gave up and flew off.

Further along, I came across a small flock of Snowy Egrets who were feeling for things in the water with their feet.  As I was watching them and taking pictures, a Great Egret flew in and joined them. Seeing the great Egret and the Snowy Egrets side-by-side really exemplifies their size difference. It looked like a mama bird with lots of babies around her.  Some of the Snowy Egrets were flashing their top knots at one another. I got the sense that it was a more an aggressive, territorial thing than a romance thing. None of the birds had their long, trailing feathers in; and none of them were sporting the pink blush in the face the Snowies get when their breeding.

Beyond the regular Oak Apple galls, there weren’t a lot of other ones out yet. I saw some Red Cones just starting to grow – looking like tiny red pimples on the leaves of some of the Valley Oaks.  I did see the curling leaf galls and “flower” galls on the ash trees, but not as much as I’m used to seeing.

As I was walking through the oak woodland, I was surprised to see a large flock of American White Pelicans fly overhead. By the time I got my camera up and focused, though, they were gone. It’s always so neat to see those big birds flying.  They don’t look like they should be able to stay aloft, but they’re so graceful in the sky.

I also got a glimpse of a Green Heron when he flew out from the rushes around the bridge area, and up into a willow tree.  There were so many twiggy branches around him, though, it was hard to get any decent shots of him.

Near the nature center, I saw some House Finches, Anna’s Hummingbirds, and a baby cottontail rabbit. The baby was a surprise; my brain couldn’t get itself around how small it was at first, and I just stared at it. I did come to enough to get a few shots of the bunny before it scrambled away, though.

Even going down to the boat launch area, I was surprised by the lack of insects. I was hoping to see dragonflies, damselflies and spiders there, but… nothing.

I walked for about three hours and then started to head home.  My insides were starting to complain, and I hurried to the restroom near the boardwalk area where my car was parked – only to find that the thing was locked shut. Seriously?! Guh! I hate it when that happens.

My First Trip to the Mather Field Vernal Pools, 03-27-19

Around 8:00 am, my naturalist class graduate Roxanne M. and I went to the vernal pools at the end of Zinfandel Blvd. in Mather Field.  Rain was threatening, and it was about 51° outside, but the rain held off until after we’d left – about 2 hours later.

I’d never been there before, but Roxanne had so she showed me some of the highlights out there – like the white pipes used for hydrology studies, and the somewhat lumpy landscape dotted with “mima mounds” around the pools.

“…One theory on the origin of Mima mounds is that they were created by small burrowing rodents such as pocket gophers (Thomomys talpoides) of the endemic North American family Geomyidae. Researchers in the 1940s found that Mima mounds tend to form in areas with poorly draining soils, so the “Fossorial Rodent Hypothesis” proposed that gophers build mounds as an evolutionary response to low water tables… It could be argued that gophers live in the mounds opportunistically but did not build them.  Consequently, gophers in mima mound fields seem to be aware of randomly distributed topographic highs and orient their burrowing accordingly in early mound creation stages. However, the mounds were already fully formed and the gophers may have just been maintaining them. Nevertheless, the fact that the surface area of a typical Mima mound is similar to the size of an individual gopher’s home range is consistent with the theory they were constructed by the rodents…”

Roxanne and I were hoping the wildflowers would be out, but there were only a few species showing. In another week or so, if we get some sunshine, the place should be covered in flowers.  We could see large swaths of Frying Pan poppies around some of the pools, but they were all closed up because it was overcast outside. Along with the poppies, among the flowers we did see were things like Butter ‘n’ Eggs, Blue Dicks, Showy Fringe Pod, Popcorn Flowers, and Jointed Charlock.

CLICK HERE for the album of photos.

We also saw some Canada Geese, Western Meadowlarks, and some Western Kingbirds. One of the Kingbirds was eating a large sphinx moth, but it was too far away for me to get a clear photo of it.  Along the road we saw a Mourning Dove, a pair of dark morph Swainson’s Hawks, and some wild turkeys.

Both Roxanne and I had brought little bowls to collect some of the pond water in so we could look for little critters in it.  We lucked out and were able to find a lot of tiny swimmers in the water including the larvae of Predaceous Diving Beetles, called “Water Tigers”, Damselfly larvae, and California Clam Shrimp.  So cool!  I need a portable microscope to take with on trips like this – and I need a book on vernal pool creatures. I don’t know very much about this kind of habitat; it’s all kind of new to me.

We both enjoyed the walk and vowed to go back to the pools in another week or so.

A Few Birds at the Cosumnes Preserve, 03-24-19

I got up around 6:30 and headed over to the Cosumnes River Preserve to see how things are shakin’ there.  It was about 44° when I headed out.

I was actually kind of disappointed. Even through a 4-hour walk which really taxed my body, I didn’t see as much stuff as I was hoping to. The ponds near the boardwalk parking lot were virtually empty. Handfuls of birds here and there; most of them out of range of my camera. Along the river trail I startled a Cottontail who, if he had been still, I would have passed by completely. But he decided to make a dash for it, then stopped out in the open. Must’ve been a young one; the adults know better than that.

I also got to see a Black Phoebe mining mud, I guess, from UNDER the boardwalk (I guess all of the other mud in the place wasn’t good enough for her). When she flew in under the boards, her wings and tail dipped in the water, and Phoebe feathers aren’t waterproof so she was kind of endangering herself with every dip.

Now, I assumed she was pulling mud OUT of there, but she may also have been creating a nest under the boards – although that seems really weird to me. If she was constructing her nest under the boards, it could be ruined if the water level in the ponds rises again (or the place gets flooded again). Phoebe nests are made primarily of mud, so if one got wet it would disintegrate, and the eggs or nestlings would drown.

I wished I could’ve gotten a camera under there to see what was really going on.

There also seemed to be an inordinate number of Audubon’s Warblers all over the property… and the Tree Swallows were vying for nesting spots in the bird boxes and the trees. But otherwise, I felt the trip was kind of a bust.

So Many Tree Swallows, 03-25-18

I got up around 7:30 this morning and headed out with the dog to the Cosumnes River Preserve and William Land Park.

At the Cosumnes Preserve, I was surprised to see dozens of Tree Swallows flying all over the place and congregating in large numbers among the tules and on the road! I guess they were sitting on the road to get warm, but I’d never seen Tree Swallows do that before. There were adults and juveniles in the mix. Because there were so many of the Swallows around, lots of the photos I took there had photo-bombing Swallows in them.

CLICK HERE to see the album of photos.

I walked along the boardwalk and around an adjacent pond, and saw a few birds (maybe about 18 species). There were a lot of Long-Billed Dowitchers “slumming” with the ducks, Killdeer, and other shorebirds; and the tiny Marsh Wrens were singing their buzzy songs from both sides of the boardwalk.

I was there for about 90 minutes and then headed to William Land Park.

Lots of Wrens and Squirrels, 03-24-18

Around 6:30 am I headed out to the Sacramento National Wildlife Refuge with the dog. They’ve opened the loop to the permanent wetlands area, so I wanted to see what that looked like these days – and I needed a nature fix. The mountains around us, which aren’t too terribly tall, had snow on their summits, and a light dusting of snow all down their flanks (which had pretty much melted by the end of the day today). It was 44º when I got to the refuge and around 51º when I headed back home. Clear and bright, though. I got some nice scenery shots while I was out there.

I saw most of the usual suspects while I was out on the preserve; and for the most part I had the place all to myself. I only saw two or three other cars on the auto route when I was driving it (although, a phalanx of cars showed up just as I was leaving. I assumed it was a birding group who were there to see the fly-out at dusk.)

CLICK HERE for the album of photos and videos.

Jackrabbits and Cottontails were out, and I also got a glimpse of a Striped Skunk and a small herd of mule deer. Otherwise, it was mostly birds. The huge-huge flocks are gone now, but there’s more variety in the different kinds of species you can see out there (if you know where and how to look for them.)

I saw American Coots, American Wigeons, Killdeer, Red-Winged Blackbirds, several Great Egrets, Western Meadowlarks, some Northern Harriers, White-Faced Ibis, Great Blue Herons, Song Sparrows, Green-Winged Teals, Northern Shovelers, White-Crowned Sparrows, a couple of Red-Tailed Hawks, lots of Double-Crested Cormorants, Pied-Billed Grebes, Ruddy Ducks, Ring-Necked Ducks, Cinnamon Teals, Golden-Crowned Sparrows, a Belted Kingfisher, Audubon’s Warblers, Black-Necked Stilts, Tree Swallows, Long-Billed Dowitchers, Snowy Egrets, Gadwalls, a Red-Shouldered Hawk, some Greater Yellowlegs, Lesser Goldfinches, House Sparrows, an Anna’s Hummingbird, and several Crows. And, of course, this time of year the Marsh Wrens are out everywhere building their nests and singing their buzzy songs trying to attract females. I got lots of photos of them.

At one spot along the route, I came across an area where there were several Ibis and Snow Egrets gathered, and a Great Egret standing nearby. One of the Ibis caught a crayfish in the water, but as soon as it lifted it up, about three of the Snowy Egrets went after it, making the Ibis drop its meal. One of the Snowys picked it up and tried to fly off with it, but then the great Egret flew over and body-slammed the Snowy making it drop the crayfish, too. The Great Egret then had to search through the turbid water to find the crayfish again so he could eat it himself.

I saw only one of the Ibis starting to get its white breeding face, and the Snowy Egrets I saw aren’t showing any signs of their breeding plumage yet. But some of the Great Egrets are… and their faces are turning neon green: a signal to other Great Egrets that they’re ready and available for mating.

I also got quite a few photos of California Ground Squirrels. I’m just enamored with those little guys. If I had the time and funding, I’d love to be able to a long-tern field study on them. This is the time of year when the females have all set up their natal chambers in their burrows and are lookin’ for love. I saw one pair of the squirrels though in which the female was not at all interested in the male who kept harassing her. Maybe she already had babies in her burrow she needed to take of, or she just wasn’t that into him, but their antics were hysterical to watch. I got a little bit of it on video and in photos, but they just don’t do the comedy justice. The male first approached the female from the front, sniffing at her, reaching out to her with a paw, touching his nose to hers. But when he tried to move in further to get a whiff of her goodies, she jumped straight up into the air about a foot and ran off. The male chased her, and the two of them went running down the road in front of my car, tails up, the male body-slamming the female occasionally to try to get her to slow down or stop for him. More jumping. More running. Then they took a break for about a second before the male tried to approach the female again and… More jumping. More running. Hah! It was exhausting to watch them. I don’t know if he ever got her or not, but it was valiant effort.

The permanent wetlands loop was kind of disappointing. They’re redone the dirt road there and cut down all of the tall grass and most of the roadside vegetation. That makes viewing easier, but because there aren’t any places now near the road with high vegetation, there’s no place for the critters to hide or eat or build nests. So there was “nothing” to see. The refuge is also going to drain the big pond there, which means for a brief period of time, as the waters shrink and the water-living bugs and crustaceans are forced into a smaller and smaller living space, the birds will have a feast. When that happens there will be a lot of activity and photo ops. But the draining of that pond also means that the Clark’s and Western Grebes won’t be able to build their floating nests on the water – which is usually a big draw for photographers. So, this might be a disappointing year for photographers at the refuge.

((The draining of the pond is done about every years to get rid of the invasive carp who get into the basin when the area floods and then get trapped there when the flood waters recede. The refuge also has to till the pond bottom to expose it to the sun, so that all of the bacteria and viruses in the accumulated bird droppings can get irradiated.))

I was at the refuge for about 5 hours and then headed back home.

Back to the Cosumnes River Preserve, 05-18-17

DAY 13 OF MY VACATION. I got up around 6 o’clock this morning and headed out to the Cosumnes River Preserve. I was looking for damselflies and dragonflies; it’s early in the season but as the weather is turning warmer, I thought they should be starting to emerge… It got up to 85º today…

CLICK HERE to see the full album of photos and videos.

At the preserve, I didn’t see a lot of dragon- or damselflies, but I did find a great example of exuvia – the exoskeleton left behind when a dragonfly leaves its aquatic body and emerges as a winged dragonfly. I was able to get a lot of close-up photos of it.  I also saw two garter snakes and got some photos of the Virginia Rail and she scurried back and forth getting bugs for her babies.  And for some reason there were a lot of crayfish all over the place; most of them in areas where the egrets and herons couldn’t get in to eat them. They must’ve figured out where it was safer… I also saw quite a few tiny Pacific Tree Frogs, and came across a small Tadpole snail.  I’m always surprised when I’m able to catch sight of the teeny stuff like that…

When I got to the preserve its was 54º, but by the time I left it was already 76º — which is “too hot” for walking.  I walked for about 4 ½ hours… and was exhausted by the time I got back home. My feet and ankles just can’t take walks that long anymore…
