Black-bellied Whistling Duck

Manuel Antonio and the Osa Peninsula are two atlas places where the Black-bellied Whistling Duck is recorded, and records concentrate in the United States, Mexico, Costa Rica, Panama, and Belize. The atlas holds about 733,000 records of the bird from 11 countries. Because the range is partial, the map indicates where these records cluster.

Recording months differ by region across the two hemispheres. Each place page in the atlas shows the particular months when the species is recorded there.
