The Celebrate Urban Birds project at the Cornell Lab of Ornithology seeks observations of interesting or unusual bird feeding behavior for its Bird Chow Challenge contest.

“Take a walk outside-you might see pigeons trying to snag a piece of pizza in the park or a flock of Cedar Waxwings scarfing up berries from a bush,” said project leader Karen Purcell, in a press release. “Maybe a gull will steal your sandwich. Look for a horde of grackles going nuts at a feeder, or an American Robin tagging along after a farmer plowing his field.”

Entries can be digital photos, artwork, or video, even a story or a poem. Show or describe avian food follies.

Prizes include bird feeders, nest boxes, sound CDs, guides, books and posters. The first 50 entrants will receive a copy of a poster showing some behaviors of American Crows, Blue Jays, and other closely-related species.
