coincidence of pigeons occurred in my reading on p. 113 of The Comforters by Muriel Spark: "Soon a pigeon flashed out from its high loft and descended to the seat beside her. She folded the thin paper into a tiny pellet, fixed it into the band on the silver bird's leg, stroked its bill with her brown fingers, and let it go. Off it flew, in the direction of Ladle Sands."
Speaking of pellets, I went on bird walk today, and while we did not see the great horned owl in Ewing Park, we did 1) hear its call and 2) see its pellet the under its tree, containing a mouse skull, fur, and feathers. Our fearless leader, Given Harper of the local branch of the Audubon Society, held the pellet in his hands for us. We also saw a bald eagle flying (gliding) high above and far away, heard flycatcher and titmouse, and saw a migrating pair of black-billed cuckoos (I saw one in motion; others saw the pair in binoculars on branches). An early-morning birder had seen a kite. We saw a different kind of kite stuck in a tree, and plenty of broad winged hawks.
Neither of these covers is the edition I am reading. The other coincidence is plot. The Comforters, written in 1955 and published in 1957, has a metafictional component, where a character is hearing voices and a typewriter tapping and realizes she's a fictional character in a novel. Just like Stranger Than Fiction, a movie I love with Emma Thompson, Will Ferrell, Dustin Hoffman, and Queen Latifah! I can't wait to see what happens!
