Common birds of San Francisco bay area

I was doing some archaeology with my photos and found some which I’d taken of birds in the San Francisco bay area eight years ago. This surprised me immensely because I did not think of myself as a bird watcher in those days. Maybe it was because The Family had already started carrying binoculars and field guides to birds on our holidays that made me take these photos in backyards and walks. I took the featured photo out of a kitchen window one morning while making a tea. I think that is a Western Wood Peewee (Contopus sordidulus). I have a couple of other photos, all of the same quality, but together they seem to defy an alternative identification.

In the same patch of ground at the same time I also spotted this small yellow and black bird. Again I have several photos, none of them very good, but all together indicating that this is perhaps the Lesser Goldfinch (Spinus psaltria). It is certainly small enough to be one, and the colour makes it unlikely that it is anything else.

Afterwards I stood in the kitchen with my tea and photrographed this dove. I hadn’t seen anything before which looks like this. It is the Mourning Dove (Zenaida macroura). The birds I saw were all common birds, with a large range and stable population. They are of no concern to conservationists. I found them interesting then, because I knew nothing of New World birds. I have a memory of planning to identify them later. I could hardly have thought that the plan would mature almost a decade later.

The commonest of American birds was new to me. I found now that I have several photos of the American robin (Turdus migratorius) apart from the one you see above. This has a much more faded red in the breast than the variety I’ve seen on the east coast. Perhaps that means it belongs to the subspecies propinquus, which is one of the two subspecies which one can see in this area. I suppose I spent a bit of time photographing this bird because it looked different from the robins I’d seen before.

Identifying the bird which you can see in the photo above was not easy, although I have several photos. The reason, as ARKive says, is that the Dark-eyed Junco (Junco hyemalis) “from different areas vary quite considerably in size, colouration and behaviour”, although it is one of the commonest birds in North America. If you look through the photos in that site, you see how different they can look. Although the Wikipedia page has several photos, none of them look like this.

I spent quite a while looking at this common starling (Sturnus vulgaris) and because I thought that I’d seen something quite similar halfway across the globe. My impression was correct. The web page of the Audubon Society says that it was brought to the Americas in the 1890s, and has since spread across this new habitat. My photos show the typical feeding behaviour of this adult male: poking at the grass repeatedly and eventually tugging its prey out of the group (photo above). I didn’t seen any flocks, though.

Finally that little song bird that is so common that I ignored it until it sat down on garden furniture right in front of me. This is the House Wren (Troglodytes aedon), which can be found everywhere from central Canada to Tierra del Fuego. That probably makes it one of the commonest of American birds. I wasn’t really looking for birds during that trip, and it is just chance that I took these photos. As a result, I have photos of the commonest of birds in the Bay Area.
