A bit far off, so rather grainy. I think I may have another shot of one, possibly even a better shot of one, on my cell phone. Certainly closer, just across the parking lot fence, but camera was in the trunk of the car so used the cell phone rather than risk it being gone by the time I got back. We'll see when I get those downloaded.
As for why this bird's name was changed, I have no idea. Either name suits, but why bother to change an established name? Or maybe both names were in use and then the one I'd learned got dropped?
