Notes on the nesting of six species of birds in eastern Ecuador

Summary. I present new information on the breeding biology of six bird species found in the Ecuadorian Amazon. I describe, for the first time, the nests of Oleaginous Hemispingus Sphenopsis frontalis and Black-eared Hemispingus S. melanotis, as well as providing the first descriptions of the eggs of Black-eared Hemispingus, Streak-headed Antbird Drymophila striaticeps, Mottle-backed Elaenia Elaenia gigas and Casqued Cacique Cacicus oseryi. I also provide the first detailed nest description for Black-banded Crake Anurolimnas fasciatus, and correct previous descriptions of its eggs.
