Migrating Birds and Cooper's Hawks

A lot of birds have been visiting our backyard these past couple months. It's been especially hot this summer, and we put out several bowls of water outside, so many different birds have been coming down to drink, bathe, and cool off. Just sitting by the window, I can see quite a few species within a short period of time.

Most of the summer birds - the grosbeaks, tanagers, and orioles - are still here, and come down to the water from time to time. Below are three photos. The first is a female Black-headed Grosbeak. The second is of the same grosbeak, along with a female House Finch, both a male and a female Hooded Oriole, and a female House Sparrow. The third photo is of a female Western Tanager (which looks very similar to a female oriole, but is stockier with a thicker yellowish bill, shorter tail, and darker wings) and a California Towhee.

Little warblers have been visiting the water as well. Most often it's an Orange-crowned Warbler, but once or twice I've seen a Yellow Warbler taking a drink there. Below are three photos. The first is of an Orange-crowned Warbler and a California Towhee, and the second two are of the same Orange-crowned Warbler bathing and showing off its bright orange crown.

As I mentioned in my last post, a few winter birds have arrived very, very early. On Saturday, I spotted another new migrant in my yard, the Black-throated Gray Warbler. I've never seen them in my yard before, and I haven't seen them anywhere this early before. Like most of the birds in my yard, it came down to take a drink, though it didn't stay long. A couple of Mountain Chickadees also came by, though they didn't stay long enough for a photo. Although the chickadees don't migrate, I don't usually see them except in the winter. I'm still not sure why these birds have come here so early. Below are two photos of the Black-throated Gray Warbler in the jacaranda tree.

I also saw a couple of little flycatchers on Saturday, the Pacific-Slope Flycatcher and the Western Wood-Pewee. Because of their similar size and shape, they can be confused at a distance or in bad lighting. In good lighting, the Pacific-Slope Flycatcher is clearly very yellow, while the Western Wood-Pewee is grayish-brown (it does have a small bit of yellowish-gray on its belly). Below are two photos. The first is the Pacific-slope Flycatcher, and the second is the Western Wood-Pewee.

On Thursday, I was doing my homework and looked up to see an adult Cooper's Hawk standing in the middle of the yard. It was just standing in the grass, looking around. Then it raised its wings a couple of times, as if warding off anything that might be nearby. It ran to one of the clay water dishes, took a drink, and sat in the water. It stayed for quite a few minutes before taking off. However, it must have been weighed down by water or maybe it was difficult to take off from the ground, since it didn't quite make it over a bush and sort of fell into it. After it righted itself and sat for a minute or two, it flew away. Below are six photos of the Cooper's Hawk. The second and third are of it raising its wings, the fifth is it sitting in the water, and the sixth is the hawk when it fell into the bush.

On Saturday, a juvenile Cooper's Hawk came by. It was trying to hunt, and flew from perch to perch trying to find a way to get to a group of House Sparrows hiding in a bush. It was clearly very unexperienced, as it tried to jump into the bush and climb in after the birds. The hawk was way too big to fit into the dense bush, and so it fell out onto the ground. It tried a second time with the same result, then sat in an orange tree for a while before finally flying away. Below are three photos of the hawk. In the first, the hawk is sitting on a birdbath, in the second, it's on our roof, and in the third, it's in the orange tree (its bill is open because it was panting; it was very hot on Saturday).

Buena Vista Lagoon August

Last Saturday was the bird count at the Buena Vista Lagoon. The sky was clear, the water level was high, and it was very hot. Unfortunately, we didn't see a single raptor. However, we still managed to see more species than we did last month. Below are six views around the lagoon.


We saw several Pied-billed Grebes around the lagoon, including a couple of young ones with stripy faces. Below are two photos of the Pied-billed Grebes (the one in the second photo is a juvenile).

There were quite a few Red-winged Blackbirds around, flying through the reeds and eating at bird feeders. Below is a male sitting on a telephone wire.

There were a few young Western Fence-Lizards sunning themselves in front of the nature center. They were very small with large heads. Below is one of them blending into a wooden railing.

There were a few Mourning Doves here and there. Below is one sitting high up in a tree.

There were several Cassin's Kingbirds sitting up on the tops of trees. Their colors were very vivid in the bright sunlight. Below is one perched on top of a sycamore tree.

There were a lot of different dragonflies zipping around. Below is a blue dasher dragonfly resting on a bush. Most of the dragonflies were probably blue dashers; they seem to be the most common species around.

As usual, there were quite a few American Crows around. Below is one of them perched on a lamppost.

There didn't seem to be as many gulls around as usual, but there were a few here and there, mainly California and Western Gulls. Below is a California gull standing on a streetlight.

There were a couple of Caspian Terns that flew in squawking. They flew around together and dove into the water after fish. Below are three photos of the Caspian Terns diving and flying around over the lagoon.

We saw a few herons and egrets around. A couple of Great Blue Herons stood very still in the reeds by the water. Below is one of them.

There were a few Mallards around, though not as many as we'd recently been seeing. Below is a female standing on a pipe.

The biggest surprise of the day was another duck. As we were standing by the lagoon, looking out over the water, a large flock of ducks flew in and around the lagoon in a wide arc. Their plumage looked a lot like female Mallards, but they weren't behaving like Mallards. They landed on the water and swam in a cluster, and as we looked through our binoculars, we saw that they were all female Northern Shovelers. Shovelers and other migratory ducks (or any migratory birds) usually don't arrive until late September or October. I've never seen birds arrive as early as August before, and I'm not sure why they're here now. Other birds have started arriving early, as well, not just the shovelers. Below is a photo of the flock of shovelers on the lagoon (there are also a few Ruddy Ducks at the edges).
