The Brant is a small goose somewhat larger than a herring gull. The hundreds that arrive each fall will have flown thousands of miles from their breeding grounds somewhere in the wet coastal tundra of Alaska and Canada. They feed on aquatic plants such as sea lettuce as well as aquatic insects, mollusks and worms.
Should you only see a few of them in either North or South Cove, just look a bit further because there are bound to be many others in the vicinity. In particular, they like to congregate amongst the rocky islets at the southern end of Rock Island. Unlike the other water fowl that winter in the coves of Salter Grove, the rafts of Brant can be quite noisy. At a distance they can sound like a social gathering of humans having very animated conversations.
