We had such fun during last year's Halloween costume contest and cannot wait to see this year's entries. Above is last year's grand prize winning crow costume created by Olivia Miseroy. She won a signed movie poster from Wes Craven! Here is the contest 411:

We want to see your inner bird and are looking for bird-tacular creations in the following categories:

• Best kid/pet bird costume
• Best adult bird costume
• Scariest bird costume
• Best group/pair bird costume

Post your photo on our Facebook page, tweet them, Instagram them with the hashtag #bestbirdcostume (or you can email us them at auduboncalifornia[at]audubon[dot]org). Winners will be determined by the number of likes each photo receives on our Facebook album combined with the number of likes it garners on Instagram. Each category winner will receive a prize and and the person who gets the most votes will win something SUPER special. We hope to announce what that is soon.

Submissions will be accepted until October 31 and voting will close November 7.

Good luck!
