Roseate spoonbill
The roseate spoonbill (''Platalea ajaja'') (sometimes placed in its own genus ''Ajaja'') is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is a resident breeder in South America mostly east of the Andes, and in coastal regions of the Caribbean, Central America, Mexico, the Gulf Coast of the United States 〔Dumas, Jeannette V. 2000. (Roseate Spoonbill (''Platalea ajaja'') ), The Birds of North America Online (A. Poole, Ed.). Ithaca: Cornell Lab of Ornithology. Retrieved 2009-11-12.

==Taxonomy==
A 2010 study of mitochondrial DNA of the spoonbills by Chesser and colleagues found that the roseate and yellow-billed spoonbills were each other's closest relatives, and the two were descended from an early offshoot from the ancestors of the other four spoonbill species. They felt the genetic evidence meant it was equally valid to consider all six to be classified within the genus ''Platalea'' or alternatively the two placed in the monotypic genera ''Platibis'' and ''Ajaja'', respectively. However, as the six species were so similar morphologically, keeping them within the one genus made more sense.
