As late fall becomes early winter this year, listserves are buzzing with exciting news of birders finding Snowy Owls south of their normal winter range! Slowly at first, but now quickly picking up steam, Snowy Owl reports continue to mount, signaling a significant movement of this species into the Lower 48 from coast to coast -- or in other words, an irruption year! But what is really causing these birds to move into our area? We need your observations of this species to learn more. Some locations are now hosting multiple Snowy Owls, and new birds are being found nearly every day. With eBird, we now have a great way to track the extent and scale of this year's invasion. Get out there and find your own Snowy Owl, and don't forget to submit your observations to eBird!
