Seal Island Landscape

The habitat on Seal Island consists of 35 acres of grasslands and 30 acres of rock ledge and boulders. This combination of habitats offers prime seabird nesting sites, with boulder fields and ledges providing nesting habitat for Atlantic puffins, razorbills, and black guillemots (FWS) – and of course gray seals.

Gray seals use the island to mate and raise pups from December – February. The average highs and lows in December range from 38* F to 23* on Seal Island, and in February the low drops to 34*F!

While closed off to humans, you can visit Seal Island virtually on the Gray Seal Live Cam!
