We have posted in the past about one of my favorite birds, the Peregrine Falcon. They are "peregrine" because they breed in the north, summer in South America.
They are partial to cliffs and mountains, which is why they are comfortable living in cities with their abundant source of pigeons and sparrows, and nesting on tall buildings and urban bridges.
The recovery of their populations east of the Mississippi is a wonder to conservationists and a tribute to what man can do to renew wildlife populations.

Walker Percy fans, of whom I am one, recall the protagonist in The Last Gentleman setting up his fancy telescope in Central Park to watch the falcons. (I am also a Dickens fan, a Wallace Stegner fan, a Mark Helprin fan... ok, I am not going to keep going down this track.)
