Comments
Birds
Roseate Spoonbill Ajaia ajaja SSC Yes *
Uncommon year-round resident, foraging & nesting success appear to be
partially dependant on estuarine salinity regimes occurring in suitable
foraging habitats
Piping Plover Charadrius melodus T T No
Occasional passage migrant or winter resident, forages in intertidal zone,
on sandspits, coastal inlets and mud flats
White-crowned Pigeon Columba leucocephala T No
Uncommon year-round resident; primarily inhabits upland tropical
hammocks, feeding on fruit-bearing species, including Ficus and
Metopium.
Little Blue Heron Egretta caerulea SSC No
Fairly common year-round resident; forages in shallow waters (fresh,
marine and/or estuarine); No apparent salinity preferences
Reddish Egret Egretta rufescens SSC No
Uncommon year-round resident; spring-summer nesting in coastal
mangroves
Appears to prefer mesohaline to hypersaline conditions
Snowy Egret Egretta thula SSC No
Fairly common year-round resident; forages in shallow waters (fresh,
marine and/or estuarine); No apparent salinity preferences
Tricolored Heron Egretta tricolor SSC No
Fairly common year-round resident; forages in shallow waters (fresh,
marine and/or estuarine); No apparent salinity preferences
White Ibis Eudocimus albus SSC No
Fairly common year-round resident; forages in shallow waters (fresh,
marine and/or estuarine); No apparent salinity preferences
Arctic Peregrine Falcon Falco peregrinus tundris E No
Migrant/winter resident; opportunistic predator, primarily on other birds
No apparent salinity preferences
American Oystercatcher Haemotopus palliatus SSC No
Infrequent visitor, forages on benthic and benthonic organisms, relative
absence may be related to lack of Crassostrea virginica
Bald Eagle Haliaetus leucocephalus T T No
Occasional sightings throughout the year; no documented nests within
project area; primarily piscivorous, no salinity regime preference
Wood Stork Mycteria americana E E No
Uncommon winter resident, although year-round in nearby Everglades;
forages primarily in shallow fresh or estuarine waters; Nesting not known
in project area
Brown Pelican Pelecanus occidentalis SSC No
Abundant to common year-round resident, but no nesting colonies within
project area; Prefers estuarine/marine salinity regimes
Black Skimmer Rhynchops niger SSC No
Rare to uncommon within project area; forages on small fish near surface,
(e.g., Menidia, Fundulus, Anchoa and Mugil); prefers estuarine/marine
salinity regimes
Least Tern Sterna antillarum T No
