No, "Bird Day" isn't some kid's cute way of saying "birthday." It's an actual, legitimate holiday (technically called "Migratory Bird Day") that you can commemorate by going on a bird behavior scavenger hunt, taking the Great Migration Challenge and signing a Bird Action Pledge.
Plus, you can look through a spotting scope or take a short bird walk, perfect for your eagle-eyed kids. We're most excited to try something called Jeop-Birdy-think it's anything like Angry Birds?
