- Black above
- White below
- Red legs
- Bill red with black tip like a blade. Lower mandible much longer, than the upper
Immature mottled upper appearance, with shorter bill.
Distribution
Breeds along Atlantic and Gulf coasts from Massachusetts and Long Island to Florida and Texas. Winters north to southern California and Virginia. Also in American tropics.
Taxonomy
Subspecies
There are 3 subspecies[1]:
- R. n. niger :
- R. n. cinerascens:
- Coasts and rivers of northern South America to Bolivia and north-western Argentina
- R. n. intercedens:
Habitat
Breeds chiefly on sandbars and beaches; feeds in shallow bays, inlets, and estuaries.
Behaviour
Tight flocks can be seen simultaneously wheeling in one direction and then another.
Diet
They are mainly surface skimmers (hence the name) tip of the lower mandible cuts through the water. They will also wade in shallow water, jabbing at the fish.
Breeding
3 or 4 brown-blotched buff eggs on bare sand, usually among shell fragments and scattered grass clumps.
They are particularly attracted to the newly-dredged sand-fill areas, which may contain colonies of up to 200 pairs. These sites will be abandoned as soon as too much grass appears.
Vocalisation
Short barking notes.
