During a recent podcast we were talking about the wonderful influx of Brant Geese that have been seen all around the coves of Cape Ann. Joey asked a great question, “how to tell the difference between ducks and geese?” Ducks, geese, and swans all belong to the Anatidae family and I could only answer that size is the predominate difference between duck and goose. If you are out on the water or onshore and trying to id whether duck or goose I think the surest way to tell is that geese are larger, with longer necks and bodies. I was curious to learn more and google led to interesting differences, some obvious and correlate to what we observe in our region, and some not so obvious.

Geese are generally white, gray, or monochromatic and both males and females are the same color. Ducks are multicolored and there are obvious pattern differences between the males and females.

Geese migrate further distances. We have seen that this past year with our Snow Goose visitor, a bird that breeds in colonies on the Canadian tundra, as do the Brants.

Another quick way to determine whether goose or duck is by what they are eating; geese generally eat grasses and grains; ducks eat fish and insects. The Snow Goose that visited Good Harbor Beach this past winter foraged for sea grass alongside the Canadian Geese.

Photographer and fisherman Brian O’Connor reported that a fisherman mentioned to him that Brants are observed in an area when there is a heavy crop of sea “vegetables” and that is precisely what is occurring in our region–the “green” waves. Sea lettuce is a staple of the Brant’s diet and it is sometimes referred to as “Brant lettuce!”

Please let us know if you see any Brants, where and at what time. Thank you to Zefra for writing last week about Brants at Lighthouse Beach. And thank you to Bill Hubbard who wrote to say that during the 40s and 50s hundreds were often seen, less so beginning in the late 50s.
