A Gray Heron has been seen on an island near Nantucket, MA. Using a wing
photo of his own and one from George Forsyth, the finder (and others) have
made a good case that the MA bird is also our NS bird. There are at least
two small notches and also some sort of white growth (??) in both photos.
You can read the comments and see the photos in this eBird report.
