Nests, Nest Placement, and Eggs of Three Philippine Endemic Birds

Abstract

We describe the nest and eggs of two Philippine endemic passerines, the Rusty-faced Babbler (Robsonius rabori) and the Blue-breasted Blue Fly-catcher (Cyornis herioti). We also describe a novel type of nest and nest placement for the Short-crested Monarch (Hypothymis helenae), and provide the first description of the eggs of this species. We discuss similarities among eggs and nests of these species with their relatives, and the need for more information regarding natural history and breeding habits for the Philippine avifauna.
