Here is a thrush I photographed in Caraca PN, Minas Gerais, Brazil. In my notes I recorded this as White-necked Thrush, Turdus albicollis. That would be new for the database, but I am not sure these photos document the bird, and since the striking white neck isn't visible here, I could have been wrong in the identification.
It looks like it has a black bill, possibly with a yellow lower mandible, which is consistant with T. albicollis. It is also very dark, with some white streaking on the throat. There does not seem to be an eye-ring, which T. albicollis should have. The legs are dark, ruling out female Yellow-legged Thrush, P. flavipes.
The common thrush in the area is Rufous-bellied, T. rufiventris. Does the dark bill rule out rufiventris, or can the bill be dark, perhaps in a female?
Pale-breasted Thrush (T. leucomelas) and Creamy-bellied Thrush (T amaurochalinus) could be present. The former should probably have more contrast between the rusty wings and grey head. The latter could have a black bill in a female. Is this bird too dark on the back?
It may be hopeless- I don't have enough experience looking closely at these birds. I need to go back and work on it, for sure.
Anyway, do these images document White-necked Thrush?
Thanks for help,
Jeff
