Another note on chickadee notes...
Donald Kroodsma is actively researching chickadee vocalizations from UMass. He
had an article in The Living Bird not too long ago--it focused on chickadees on
Martha's Vineyard. Dennis Paulson is interested in this subject and started a
very short-lived topical thread on Tweeters a couple of years ago.
