Birders tend to go where they find interesting birds. Susan Whiting, Lanny McDowell, Bob Shriber, Nancy Nordin and myself teamed up to find 60 species on the morning of Oct. 27, most of which were songbirds. We generally do not find that many species in three hours. Some of us were looking in one direction when others were looking elsewhere and finding other species.
Migration can be interrupted by strong northeasters like we experienced last weekend. The website Birdcas (birdcast.info) uses radar to monitor the skies for migrating birds and posts the results.
