The original bird is the center for both of these comparisons.

The first series compares to Black-chinned, the second compares to Costa's.
IBird is usually pretty rigorous on IDíing before adding to the site.
When reading a description of the Costaís there is no mention of the white on the bottom of the tail feathers - from what I can see. While the Black chinned does have the white outer tail feathers which show in the photo and descriptions of birds Iíve seen and in my own photos of black chinned. Why do you think it is not a Black chinned?
