The Chivi Vireo was previously considered to be conspecific with the Red-eyed Vireo but clearly they are different birds based on the fact that the South American birds don't migrate to North America, they actually migrate south to breed. Actually some of the sub-species within this complex don't migrate at all. They inhabit mostly the northern parts of South America with some movement further south during breeding. I currently only have one really poor picture from northern Colombia but I am going to northeast Brazil later next year and anticipate getting better pictures as they are year round residents there.
