The study of birds isn't just for ornithologists.
Because we interact with them so frequently, birds offer a lot of things to learn about our environment.
One of the best teachers about all things feathered is the Cornell Lab of Ornithology. The lab provides online courses and webinars on birds and bird-watching. Its newest offerings include webinars on waterfowl identification and tutorials for beginning birders.

With resources like these, the next time a bird flies by the window might be the start of a lifelong study.
