Speak softly and carry a long lens
How to tell the two new species apart?
Range apparently overlaps in Costa Rica, where this photo was taken.

Both have brownish tinge on the top/back of the head; is this spot more extensive on species one than the other? (edit: Yes, apparently it's more obvious on russet-naped.)
I have lots more photos, if you want to see a particular part of the bird(s). (Two adults and two juveniles traveling together, presumably a single family.) Not sure whether these two photos show the same individual.
edit to add: on Cornell's Neotropics website, the range maps argue in favor of russet-naped (this was at La Fortuna, in the northern part of the country). My bird's russet spot seems large enough to support that, but I'm just using a couple of online photos for comparison, not sure what the range of normal variation is.
