Pogonotriccus (?) zeledoni

Lawrence

, 1869,

Dota, Costa Rica

.

Usually treated as conspecific with P. burmeisteri, but see above; from online evidence, birds singing like zeledoni penetrate as far S as La Paz, Bolivia, where could intergrade with P. burmeisteri#R; “leucogonys group” long recognized as distinctive, and sometimes treated as separate species#R. Five subspecies recognized.
