These birds represent three populations of toucans sampled by John, Jason, and Alex during their 2007 Amazonian Expedition, as well as other earlier collecting trips.

The dots represent locations where specimens from the three populations were found. As you can see, each population lives within specific, river-bordered Areas of Endemism—zones containing species unique to that region.
