Abstract:Recent observations of terns, either the Old World Little Tern
(Sterna albifrons) or the New World Least Tern (Sterna antillarum), at Pearl and
Hermes Reef in the Northwestern Hawaiian Islands have documented that one
of these species bred there in 1988 and possibly also in the several preceding
years. Two small Sterna terns were first observed at Pearl and Hermes in 1984,
and the numbers subsequently observed there gradually increased until five birds
were recorded in 1988. In 1988 a nest containing three eggs was found, and at
least one egg produced a nestling. No small Sterna terns were seen during a
2-week visit to the atoll in 1989 or a 2-day visit in 1990. No specimens were
collected, and photographs taken do not permit specific identification of the
birds. We favor S. albifrons sinensis because there are now specimen records of
Asiatic Little Terns from French Frigate Shoals and Midway Atoll and a sight
record from Laysan Island, and because a review of prevailing wind systems in
the Pacific and other vagrant bird records from the Northwestern Hawaiian
Islands suggest that such birds are more likely to arrive from the west than from
the east.
