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.

State Ranking Justification [-]
Yellow-crowned Night-herons are uncommon breeders in New York State and are restricted to the Lower Hudson-Long Island Bays (Levine 1998, McCrimmon 2006). This species depends almost entirely on crustaceans for food and could rapidly disappear if food sources become scarce. Increasing coastal development, habitat degradation, and human disturbance are significantly threatening nesting and foraging habitat. (Andrle and Carroll 1988, Watts 1995).
