If you're a bird lover like me, you probably can't wait for Spring and the arrival of our colorful feathered friends. Not that we haven't had our share of Winter birds at our feeders (and even a red-tailed hawk!).
eNature.com has a great website with information, colorful maps, and pictures of the birds that will be migrating through your region of the country.
I think this would make a great activity for students to learn not only about birds, but about geography, and even math! You could calculate the distance birds traveled, and make predictions about when the birds would arrive in a particular location
