New England is not known for its snow geese. In fact, most snow geese that I have seen in New England are “stray” individuals hanging out with Canada geese. The massive flocks seem to be reserved for nearby states such as Delaware, Maryland, Pennsylvania and New York. There are, however, pockets of New England that host large numbers of snow geese for relatively short periods of time. Northern Vermont comes to mind for such a spectacle.
Snow geese are one of the world’s most numerous species. Most snow geese are white (hence the name) but young ones are grayish and there is a blue morph variety. Here’s an interesting tidbit from allaboutbirds.org: “In wintering and migrating flocks that are feeding, lookouts keep an eye out for eagles and other predators. Upon sighting a threat they call out to the rest of the flock, which may take flight.”
Happy fall migration.
