But there is some controversy over what kind of bird it is.
There is no doubt whatsoever that the bird was a finch. However, what kind? Most likely a house finch, because they are common, and the most likely to live in a big auditorium thingie and not be fearful of people.
This is the continuation of a discussion of loons, skeptically viewed. I am not skeptical about loons themselves. I know they exist. In fact, I just spent the last half hour watching Mom and Dad loon (whom I cannot tell apart, by the way) feeding Junior I and Junior II (whom I also cannot tell apart) what I have determined to be mostly crayfish, but also the occasional minnow.
