Volume 29: The Second Nebraska Breeding Bird Atlas

ABSTRACT

The Second Nebraska Breeding Bird Atlas presents range maps and species accounts of 225 species. This project used standardized atlas criteria and methods to re-survey the breeding avifauna of Nebraska. I used the data gathered to compare against the initial atlas project to detect population shifts, reveal range changes, and species responses to novel pathogens, new pesticides, changing agricultural practices, and a changing environment. The project documented northward expansion of 14 species. Using data gathered by standard atlas methods revealed changes in some species that was not detected by other methods. Overall, the project demonstrated the need for recurring projects to help track changes that may not be detected.
