General Comments The Roseate Tern is one of the more elegant and graceful of the tern species, and because it is a globally rare species -- Federally listed in the United States -- the sighting of one in the state is always memorable. Though Roseate Terns nest in both the New World and in the Old World, its nesting populations are highly fragmented, and the relatively small population in the Canadian Maritimes and northeastern United States is highly monitored/managed (to keep gull and other predator populations controlled). It is strictly coastal/oceanic, and birds reach the breeding grounds essentially out of sight of land; normally, in North Carolina one must try to find a Roseate Tern by taking a pelagic trip, but few trips see the species. There are numerous coastal records, and the species has actually nested along the coast on one occasion, and possibly has done so on a few other occasions. There are literally no inland records (including the Tidewater zone), including a lack of storm-carried birds to inland lakes. Roseates winter south of the United States.

Coastal Plain Transient and summer visitor coastally and offshore. In the warmer months, rare along the northern and central coasts (including the offshore zone), south to Carteret; very rare along and off the southern coast. Every few years, one or two birds in full breeding plumage appear in breeding colonies of other tern species, seemingly acting as if breeding. However, the only conclusive nesting was in the Cape Lookout area, on 23 May 1973, when a pair with two eggs was observed [Chat 39:20-21 link]. Main occurrence from early May to early Sep, sparingly to late Oct. There are, oddly, no Apr records, but a specimen found on 20 Jan 1937 at Cape Hatteras (Birds of North Carolina) is remarkable, though one wonders how long the bird had been dead, as this species is essentially absent in the country after Oct. Peak counts: 20, offshore, 9-10 Sep 1979 (after Hurricane David); 7 on four dates.
Piedmont No records.
Mountains No records.
Finding Tips The most likely spot to find this species used to be in the tern colony at Cape Hatteras Point, but this colony has disappeared in recent years. The best chance now is on a pelagic trip in the latter half of May, and that is perhaps only a 10% chance or less.
