To determine what constitutes suitable habitat for Least Tern populations on the Gulf coast of Florida, we surveyed six habitat variables at 11 occupied and 11 unoccupied sites and at an area.

permanent river system changes, the least tern is vulnerable to water level fluctuations during the nesting season and loss of habitat because of vegetation growth. Disturbance of nesting sites by predators, people, pets, and livestock all negatively impact least tern populations.

OCCURRENCE AND NESTING OF THE LEAST TERN AND OTHER ENDANGERED SPECIES IN BAJA CALIFORNIA, MEXICO BARBARA W. MASSEY, Knoxville Avenue, Long Beach, California The California Least Tern (Sterna albifrons browni) breeds from San Francisco Bay south along the coast of California to the Mexican border.

Human activities not directly associated with habitat loss, including harassment of adults and young, and destruction of nests also contributed to reducing local populations.

Least terns are migratory and only occur in Oklahoma only during the breeding season. Depending on habitat availability, tern nesting colonies can range from 2 to 70 pairs.
