They may be building a home.
But when they are whacking loudly on your roof or tin chimney cap (the louder, the better) we know...
...if a male bird is eavesdropping, the message they get is, "Don't mess with me, I'm the biggest, baddest woodpecker around!"
If a female flicker hears the hammering, she just might think, "Wow, what a hunk," and come a little closer to check him out in person. (more)
Not to be confused, of course, with the old Russian Woodpecker, who pecks peeked over the horizon. Why? To keep an eye on U.S.
