Roseate Spoonbills

The roseate spoonbill is a gregarious wading bird of the ibis and spoonbill family.It is a resident breeder in South America mostly east of the Andes, and in coastal regions of the CaribbeanCentral AmericaMexico, the Gulf Coast of the United States [2][3] and on central Florida's Atlantic coast.The roseate spoonbill is 71–86 cm (28–34 in) long, with a 120–133 cm (47–52 in) wingspan and a body mass of 1.2–1.8 kg (2.6–4.0 lb).Like the American flamingo, their pink color is diet-derived, consisting of the carotenoid pigment canthaxanthin. Another carotenoid, astaxanthin, can also be found deposited in flight and body feathers.[9] The colors can range from pale pink to bright magenta, depending on age and location. Unlike herons, spoonbills fly with their necks outstretched. They alternate groups of stiff, shallow wing beats with glides.This species feeds in shallow fresh or coastal waters by swinging its bill from side to side as it steadily walks through the water, often in groups. The spoon-shaped bill allows it to sift easily through mud. It feeds on crustaceansaquatic insects, frogs, newts and very small fish ignored by larger waders. In the United States, a popular place to observe roseate spoonbills is "Ding" Darling National Wildlife Refuge in Florida. Roseate spoonbills must compete for food with snowy egretsgreat egretstricolored herons and American white pelicans.Nestlings are sometimes killed by turkey vulturesbald eaglesraccoons and fire ants.Roseate spoonbills are pretty birds.
