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.

A Killdeer Baby Hunts for Worms, 07-29-18

I went over to the Cosumnes River Preserve hoping to see better examples of wasp galls there and was very disappointed. I found a few, but not nearly as many as I feel there should be this time of year. With 99% of the water gone from the preserve, there wasn’t a lot of anything to see…

There was still a bit of still a bit of shallow muddy water in the slough that ran alongside the road, and around there I was able to find a Killdeer mama and her two chicks. The babies were hunting for bugs and pulling worms up out of the water while mama stood guard. Some of the worms the babies found were longer than the chicks were tall, so the babies would yank them up as far as they could and then gobble the worms up before they had a chance to escape underground again. At one point, both babies rushed over to mom and snuggled under her feathers to warm themselves up a bit before they went scavenging again.

I also saw some tiny jumpy frogs and several crayfish interacting with one another in their slow-moving way. It looked like some of the crayfish had tried building chimneys in the mud, but it was too wet, so the structures collapsed in on themselves.

Even in crappy-looking habitat, Nature seeks to survive.

Saw My “Nemesis Bird”, 07-04-18

Happy Fourth.  I went out to the Cosumnes River Preserve for a walk and was disappointed to see most of the water now gone from the slough by the boardwalk paring lot. That was the only “wet” left in the wetlands area – and animals that depend on that water don’t have ready access to it anywhere else.

Anyway, I hung around the slough for a while to look for early summer galls and insects, and while I waited I did get to see a few birds.  Belted Kingfishers are like my “nemesis” birds. I’ve spent YEARS trying to get a halfway decent photo of one of them. They’re super-fast and super shy… So, I was overjoyed when this female stopped on a tree across the slough from me and posed for a while.  I also saw a Green Heron who was “caw-honking” to another one across the road from it: call and response. I’d never heard that from this species before, although I’m sure they do it all the time, so that was cool, too.

Bushtits, several Great Egrets and Snowy Egrets, Killdeer, and some Tree Swallows were among the other birds that came by.  I also saw the head of a Red-Eared Slider Turtle and a Western Pond Turtle poke up from the shallow water at different intervals.

As for the galls, I saw some Oak Apple wasp galls, Ash Flower galls, Spiny Turbans and a few Round Wasp galls. It’s really too early in the season for most of them. Another month and different species should be popping up all over the place.

When I was done walking at the slough, I drove up the road to the nature center and just walked the boat ramp walk there.  Lots of people taking their kayaks down to the river, but not a lot of critters or bugs. I was hoping to see some dragonflies and damselflies, but no such luck. I did get to see a little Trashline Spider, though, and a gorgeous male American Goldfinch.

I was out for about 3 hours and headed back home.

Decompression Time at the Wildlife Refuges

The dog and I headed to the Sacramento National Wildlife Refuge one day this week to decompress. Sometimes you just need to listen to your body and do what it wants…

We stopped at the Colusa refuge first (which is right on the way), and drove the auto tour there. Not a lot to see, really, but their ponds are starting to fill in nicely. Finally. I did see some female pheasants, several egrets, and lots of White-Faced Ibis among the usual suspects. The best find there was seeing a Red-Tailed Hawk and a Turkey Vulture sitting in the same tree.  The hawk had a dead Coot it was having for breakfast, and the vulture was sitting nearby hoping the hawk would drop something.

Oh, and I also saw a Great Egret with a vole it had just caught. The vole was still kicking when the egret swallowed it down.

Then we went on to the Sacramento refuge. There were lots of Black-Tailed Jackrabbits around, scurrying from one place to another, but the California Ground Squirrels aren’t out yet. (This is the time of the year when they have their babies, so most of the squirrels are still underground.) We saw most of the usual ducks and geese, both Great Egrets and Snowy Egrets, lots of Coots and Killdeer, some little Warblers, Pacific Pond Turtles, the last remnants of the Snow Geese flocks, and Ruddy Ducks. We came upon a Red-Tailed Hawk that was preening itself and didn’t mind if we watched, so I got some video and lots of photos of him (including one where he’s looking down between his legs at us. (Hilarious.)

The Marsh Wrens were out singing, and the Pied-Billed Grebes were hooting.  I came across one Marsh Wren that looked kind of odd to me; it’s coloring was different than I’m used to seeing. There were speckles all over its back.

When I got home, I posted a photo of it to a bird-identification group on Facebook, and they confirmed it was a Marsh Wren. Unbeknownst to me, the wrens actually have a few color variations, and this was one of the variations I hadn’t really seen or noticed before. So that was a first and a learning moment. I saw a few more female pheasants here, along with way too many Black Phoebes and a Great Blue Heron.  But here, the best find of the day was a Bald Eagle. I didn’t get many photos of it because it was high overhead in a tree, and I couldn’t get a good angle on it, but those guys are always great to see.

Galls, Galls and More Galls 08-20-17

I was out the door by 6:30 to go to the Cosumnes River Preserve.  I was hoping to be able to get photos of dragonflies on their wetland areas… but the whole wetland area was completely dry. There was only a little bit of water in the slough along the road.  That was disappointing.

But I still wanted to walk, so I walked along the boardwalk and behind the slough, taking photos of the different galls I was able to find.  Among the galls, I found on the oak trees examples of Red Cone galls, Spiny Turbans, Spangles. Saucers, Yellow Wigs, Gouty Twig galls, Oak Apples, Rosette galls, and Clubs.  There were also lots of Flat-Topped Honeydew galls, and some of them were exuding so much honeydew that the branches and leaves of the tree were dripping with the stuff.  It made handling things really sticky… I also found some galls on the Ash and Willow trees.

I only saw about 4 birds while I was out there, which is also unusual, and got photos of a Great Egret, a Killdeer and a Black Phoebe.  So, it wasn’t the best day for a variety of photos, but the morning weather was nice, and I was able to walk for about 3 hours so I got some exercise.
