Banded Ani

We came across this Greater Ani on the very last day of our birding tour in Panama.  Like all of the Ani species we saw (Smooth and Grooved-billed) at first they appear black but when you look closely their feathers are a combination of dark blue, purple, and black.  It wasn’t until I got home and processed the photographs that I noticed that this one was banded.  I’m going to find out if I can track down when and where it was banded.
