Size Comparison
Habitat Comparison
Common Starling
Open countryside, farmland, parks, and urban areas. Forms enormous communal roosts in winter, especially in urban environments.
Roseate Spoonbill
Shallow coastal lagoons, estuaries, mangroves, and freshwater marshes. Nests in colonies in trees and shrubs.
Song & Call Comparison
Common Starling
A complex mimic: rattles, whistles, clicks, and squeaks mixed with imitations of other birds. Song is a continuous medley. Also gives harsh 'scheer' alarm and chattering.
Roseate Spoonbill
Low, grunting and guttural croaking sounds at nesting colonies. Generally quiet. Alarm calls are softer croaks. Vocalizations lack melodic quality; purely functional colony sounds.
Geographic Range & Migration

Southeastern United States, Caribbean, Mexico, Central America, and South America to Argentina.

Roseate Spoonbill
The roseate spoonbill is the only spoonbill species in the Americas and one of the most striking wading birds in the Western Hemisphere. Like flamingos, their pink color comes from carotenoid pigments in their crustacean prey. Nearly hunted to extinction for their plumes in the 19th century, they have recovered substantially.
