摘要

The Gray Kingbird (Tyrannus dominicensis) breeds from northern Colombia and Venezuela, excluding Central America, northward to extreme southeastern North Carolina (Brunswick County) and the Florida Panhandle. Gray Kingbirds nest in small numbers on the southeastern Atlantic and eastern Gulf coasts of North America, but at widely separated locations and at irregular intervals. North of Florida, Gray Kingbirds have been found nesting only a few times, most often on the coast of Georgia. None has nested in South Carolina since the 19th century. In North Carolina the first confirmed nesting was in 1997. Since the early 1960s, nonbreeding (vagrant) birds have become more frequent on the Atlantic coast in spring, and some linger into the breeding season (May-June). This paper reviews the occurrence of the Gray Kingbird in the northeastern part of its range, from northwestern Florida and neighboring Alabama to North Carolina, and discusses the possible factors affecting its breeding distribution on the southeastern Atlantic coast
