Common Tern, adult and juve, 8/15/15

commonternadultandjuve

About 3000 pairs of Common Terns local to NH and Southern Maine nest and raise their young in a colony on Seavey Island in the Isles of Shoals. After fledging, the juveniles which lack the full black cap of adults, follow their parents to the mainland but continue to be fed and cared for until migration south begins at the end of August.

Great Black-backed Gull 8/5/15

greatblackbackedgullandcrab

Lord of the Gulls, the Great Black-backs are more predatory than other gulls, not only hunting fish, crustaceans and molluscs but frequently preying on the eggs and chicks of other seabirds of the North Atlantic, like terns, alcids, gannets, and eider. They are also kleptoparasitic, meaning they frequently steal the catches of other birds like Herring Gulls and Common Terns, and have even been known to rob some of the larger hawks of their kills. They are monogamous birds, breeding in small colonies, and typically live for 20 or more years.
