Birds Are Weird is the 4th Penny Arcade book under Dark Horse, collecting all Penny Arcade comics from 2003.
The cover art was done by Mike Krahulik, although the idea for the final draft came from a commenter on his art blog, Gabeart.
Birds are weird was published by Mike Richardson, edited by Mike Carriglito (Assisted by Samantha Robertson), and designed by David Nestelle.
The art direction was not done by Krahulik himself, but rather by Lia Ribbachi.
The Forward for the book was written by Karen Travis, who is known to have come up in Penny-arcade news posts before, having been mentioned for her Science-fiction novels.
This book ends with a collection of Mike's art from the early years of Penny Arcade and even further back, with commentary by himself and Jerry.
