Funny how often birds are considered scary in fictional movies and literature. Groups of crows, for example, are called "murders." And Edgar Allan Poe was haunted by a raven. Then there's the whole thing with that classic Alfred Hitchcock movie The Birds...
The people at the Cornell Lab of Ornithology think the "scary" bird behaviors people see in their own backyards can easily be explained. In fact, they are challenging people to take photos, do a painting, write a story or poem, even shoot a video showing crows, pigeons, starlings, an owl, or any kind of bird doing something puzzling or strange. They will then reveal what the behaviors are really all about.
"There’s usually a perfectly natural, non-scary explanation!" they say on their website.
This seems like a great activity for school groups, homeschoolers, and parents who want to do some backyard naturalist activities in fall. You can find more info on their website at: http://www.birds.cornell.edu/celebration/challenge
