The beauty of fall migration is that some migrants unexpectedly persist. Of course daytime temperatures in the low 70s, help.

The Oak Bluffs pumping station used to be a go-to site for finding migrating songbirds.

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.

Most, but not all Baltimore orioles have left for points south by now, but some will linger into January.

Migration will peak in these next couple of weeks, so this is a good time to be out and about looking for birds.

What a difference one week makes. Last week included 14 species, eight of which were migrating through rather than species that nest on the Island.
