Conservation status | Several populations are endangered. On coasts, nesting areas often disturbed by beach-goers. On inland rivers, fluctuating water levels (from releases from major dams) often flood out nesting sites on sandbars. |
---|---|
Family | Gulls and Terns |
Habitat | Sea beaches, bays, large rivers, salt flats. Along coast generally where sand beaches close to extensive shallow waters for feeding. Inland, found along rivers with broad exposed sandbars, lakes with salt flats nearby. In winter found along tropical coasts, sometimes well out to sea. |
Audubon Connecticut’s priority bird species are birds of significant conservation need, for which our actions, over time, can lead to measurable improvements in status. Some of these species are listed as vulnerable or near threatened on the International Union for the Conservation of Nature’s Redlist. Others are species of conservation concern on the National Audubon Society’s Watchlist or identified as priorities by Partners in Flight. Many priority species are also listed as endangered, threatened, or of special concern in Connecticut and are included in Connecticut’s Wildlife Action Plan. The breadth of this list reflects the dramatic loss of habitat and the pervasive threats that confront birds and other wildlife.
Forages by flying over water, hovering, and plunging to catch prey just below water's surface. Sometimes dips down to take prey from surface of water or land, and may catch insects in flight.
1-3, perhaps rarely more. Buff to pale green, blotched with black, brown, gray. Incubation is by both sexes; female may do more in early stages, male more later. In very hot weather, adult may dip into water and wet belly feathers to cool eggs. Incubation period 20-25 days. Young: Leave nest a few days after hatching, find places to hide nearby. Both parents feed young. Age at first flight about 19-20 days; young may remain with parents another 2-3 months. One brood per year, sometimes two in south.

Fish, crustaceans, insects. Diet varies with season and location; mostly small fish, crustaceans, and insects, also some small mollusks and marine worms.
Nests in colonies, sometimes in isolated pairs. In courtship, male (carrying fish in bill) flies upward, followed by female, then both glide down. On ground, displays include courtship feeding. Nest site is on open ground (or on gravel roof). Nest is shallow scrape, sometimes lined with pebbles, grass, debris.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.
