What does spring migration look like? Until now I could only imagine it. I’ve often wondered where I could find up-to-date tracking information on bird migrations. Building a strategic network of bird alerts to subscribe to and read each day would be one method, of course. Recently though, I discovered not one but two birding blogs that present Doppler radar tracking of migrating flocks: Badbirdz–Reloaded, based in Florida, and Woodcreeper, which covers New Jersey. Their posts from the last few days — Feeling the Zugunruhe! [migration restlessness] and Migrants Just Making it into New Jersey offer animated Doppler radar images of birds on the move. Fascinating!

According to Badbirdz–Reloaded, both sites were inspired by Noel Wamer, a birder from Northeast Florida with a passion for tracking bird migrations using radar. Noel was apparently quite a personality, as a Woodcreeper tribute post to him from March 2007 attests.

If Noel taught these bloggers how to use radar to track birds then he has done a great service to everyone. Both sites extend that knowledge with pages for explaining how this is done. Badbirdz–Reloaded.com has a Birds and Radar Primer with several important links, including a New Jersey Audubon article How NEXRAD Sees the Atmosphere. Woodcreeper.com provides a Radar & Migration FAQ with a link to Radar Ornithology: Introduction¬† of the Clemson University Radar Ornithology Lab.

Although it seems to be a firmly established field, radar ornithology represents a whole new aspect of birding for me. It is exciting to discover a brand new aspect of hobby that you’ve been enjoying for some time. There is so much to read and learn. I better hurry though. The birds are coming and now I can see them.
