However, from reading about Starlings, I know that some birds have different colored feathers over the course of the year. So, this must have been a Goldfinch in winter plumage. Given the information that I have, and the information collected by my friends . . . Everyone knows that any bird who pecks at trees is a woodpecker. Tweety is a bird.
All birds can fly.
Therefore, Tweety can fly. Birds fly, but penguins and dead birds do not. The heavier a bird is, the larger wingspan it must have to stay in the air. I saw last week. Hm, I saw this bird when I was on my beach vacation.
