This brief annotated list of Nebraska's breeding birds is the direct outgrowth of the work involved in the preparation of a forthcoming book titled "The Birds of the Great Plains," which will include range maps for all species except extinct or extirpated ones, and will also provide information on breeding habitat, nest location, clutch size, incubation period, and breeding biology. The purpose of the present compilation is to provide a convenient summary for Nebraska alone, amplifying some of the more general statements of that book, and pointing out uncertain or interesting situations needing further attention from field ornithologists.

This is in large measure the result of the fact that all of the species are forest-adapted, and generally are associated with tropical to sub-tropical communities, where opportunities for easy observation are virtually absent.
Not only is this the largest genus of the subfamily Odontophorinae, but also the species tend …
