Young birds are paler and duller than adults, and lack the tail rackets and black breast spot.[

It occurs from eastern Honduras through the Caribbean slopes of Nicaragua, Costa Rica, and Panama, and continues on the Pacific slope of Panama into northwestern Colombia and western Ecuador. In elevation it ranges from near sea level to in Costa Rica and to in Panama and Ecuador. In Peru it can be found locally to but more generally to .[
