Owls

The, or rather one or more species of owl, was introduced in New New York to wipe out rats and pigeons. While the owls proved largely successful, they themselves replaced both species as the most prevalent pests in New New York. Owls are still capable of flight but feed on trash and have been seen exiting holes in walls, suggesting they live there. Owls, according to Walt, lay dodecahedral eggs which hatch into Owl larvae. Owls can be domesticated and be taught to attack trespassers. They also appear in the first level of the game, standing on top of cameras at Planet Express.

Eradication
Owls are usually caught in owl traps, such as "DEF-CON Owl Traps", the operation of which sounds much like a 21st century mouse or rat trap. They occasionally also get caught in spider webs. Walt, Larry and Igner posed as "Smother Bros. Pest Control" who are exterminators, deal with disposing of owls and a variety of other pests.

Trivia

 * In the non-canon sequence of "Reincarnation", multiple owls circle the Planet Express headquarters.
