Black Skimmer (Rynchops niger)
General Information
Black skimmer has a remarkable bill, with base bright orange-red and
black tip. Flexible lower mandible is flattened and longer than the
upper, about 1/3 more. Upper mandible is rounded, leaving a space
between both. It is the unique bird having vertical pupil, allowing
it to reduce them as a simple chap when in front of the sun, or to
open as a circle with weak light. Black skimmer has black cap and
mantle, contrasting strongly with white underparts and forehead.
Upperwings are black, with fine white edge. Underwings are pale.
Wings are very long. Legs are orange-red and short. Feet are
orange-red and webbed. It has short white tail with black centre
feathers. Tail is square or slightly forked. Eyes are dark brown.
Both Bec-en-ciseaux noir sexes are similar, with male slightly
larger than female, and with longer bill. Juvenile is similar to
adult, with mottled black and white back and head.
Habitat and Range
Black skimmer inhabits in coastal marshes, and in
sandy shores, shallow bays, inlets and estuaries. Typical roosted
areas are situated on public beaches, with human activity, or
estuarine sand bars with shorebirds, gulls and terns.
Black skimmer lives in southern North America,
Caribbean and South America. It breeds in North and South America.
Northern birds winter in Caribbean and South Bec-en-ciseaux noir
American birds make some short movements to feed.
