State Protection: Protected Bird
Defined as a Protected Bird by New York State law. This species may not be hunted or taken at any time in New York.

Federal Protection: Migratory Bird Treaty Act
The Migratory Bird Treaty Act implements various treaties and conventions between the U. S. and Canada, Japan, Mexico and the former Soviet Union for the protection of migratory birds. Under this Act, taking, killing, or possessing migratory birds, including nests or eggs, is unlawful unless specifically permitted by other regulations.


State Rarity Rank: S2S3
A State Rarity Rank of S2S3 means: Imperiled or Vulnerable in New York - Very vulnerable to disappearing from New York, or vulnerable to becoming imperiled in New York, due to rarity or other factors; typically 6 to 80 populations or locations in New York, few individuals, restricted range, few remaining acres (or miles of stream), and/or recent and widespread declines. More information is needed to assign a single conservation status.

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?
Snowy Egrets use their bright yellow feet to stir up sediments in the water and frighten prey out of hiding places (Willard 1977 and Hom 1983 cited in Parsons and Master 2000).

State Ranking Justification [-]
The Snowy Egret is known to occur in nine counties in New York State including Bronx, Erie, Kings, Nassau, New York, Queens, Richmond, Suffolk, and Westchester counties (McGowan and Corwin InPress, New York Natural Heritage Program 2007). After the population reached its peak during a period of fluctuation in the mid-1970s, numbers appear to have declined slightly in recent years (Peterson cited in Andrle and Carroll 1988). In general, Snowy Egret populations are declining along the Atlantic Coast (Parsons and Master 2000) and nationwide (Kushlan et al. 2002 cited in McGowan and Corwin In Press).
