High Quality Content by WIKIPEDIA articles! The American White Ibis (Eudocimus albus) is a species of wading bird in the ibis family Threskiornithidae. It occurs from the mid-Atlantic and Gulf coast of the United States south through most of the New World tropics. This ibis is a middle-sized bird with an overall white plumage, bright red-orange down-curved bill and long legs, and black wing tips that are usually only visible in flight. Males are larger and have longer bills than females. In the breeding season, the range spans along the Gulf and Atlantic Coast and also along the coasts of Mexico and Central America, and birds gather in huge colonies near water. Outside the breeding period, the range extends further inland in North America and also includes the Caribbean. It is also found along the northwestern South American coastline in Colombia and Venezuela. Populations in central Venezuela overlap and interbreed with the Scarlet Ibis. The two have been classified as a single species.
