Under this Act, taking, killing, or possessing migratory birds, including nests or eggs, is unlawful unless specifically permitted by other regulations.

State Rarity Rank: S2
A State Rarity Rank of S2 means: Typically 6 to 20 occurrences, few remaining individuals, acres, or miles of stream, or factors demonstrably make it very vulnerable in New York State.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Did you know?
Due to its decurved bill and dark color when spotted from a distance, the Glossy Ibis is sometimes called the Black Curlew (Davis and Kricher 2000).

State Ranking Justification [-]
New York is near the northern limit of the Glossy Ibis' breeding range, with breeding populations being restricted to non-barrier and salt marsh islands in Long Island and around New York City, along with breeding on one of the Four Brothers Islands on southern Lake Champlain (McGowen and Corwin 2008; New York Natural Heritage Program 2009).
