Cooler weather is finally starting to show up as far south as Louisiana (relatively speaking; we're dropping from highs in the mid-90's to highs in the mid-to-low-80's, but we'll take what we can get).
I was hoping to get some good fall migrant pictures in my yard this year, but so far there hasn't been much of anything to photograph. However, while out in California a couple of weeks ago, I managed to snag the goldfinch trifecta (American, Lesser, and Lawrence's, all in one day), and saw this one just in front of the car in a parking lot. At first, we wrote it off as an American Goldfinch already changing into his winter garb, but the more I looked at the picture, I realized the bill was wrong (Lesser have dark bills; American have pinkish bills) and there was more white than should be in the wing of an American-and in the wrong places. Additionally, if I'd thought about it, the day we saw this bird (September 13), an American would likely not have completed molting into his winter plumage.
So a Lesser Goldfinch it apparently is, which further illustrates how we should do careful study of what we think we see.
