The notes that follow, pertaining to recent studies on avian collections made in Panamá, include descriptions of two species and two geographic races not known previously. The two named from Darién are based on specimens received from the Gorgas Memorial Laboratory in Panamá and derive from recent field work directed by Dr. Pedro Galindo. Included with these are further records of birds from the little-known island of Escudo de Veraguas, situated 18 kilometers at sea off the base of the Valiente Peninsula, Bocas del Toro, and report of two North American migrants not found previously in the republic.
