Ice Age Dodos
The page image comes from the movie Ice Age which has a group of dodos that are preparing for the Ice Age. However, at the point they're introduced they've only gathered three melons, one of which the main trio needs to feed the human baby. They end up wiping out their entire flock right then and there just trying to defend the melons, starting with the flock's last female killing herself and the rest falling to their deaths.
