State Ranking Justification [-]
Forster's Terns are a recent addition to New York's avifauna with the first nest found in the state in 1981 (Levine 1998). New York is the northern extent of their eastern range. They are currently threatened by habitat loss and historically, in parts of their range, populations have likely been affected environmental toxins (1960s-1970s) and hunting for feather collection by the millinery trade, or hat making industry (1880s). As populations increase in New York they may be restricted by habitat availability, human disturbance and rising sea-levels due to climate change.
