The Ornithology Division performs both applied and basic research. Most is specimen-based and centered around our state-of the-art molecular laboratory facility.

Much of the Ornithology Division's recent research is in the area of conservation genetics. In this work, population genetic techniques are used to identify genetically unique populations, define population boundaries, estimate current and historic population sizes, and estimate the degree of gene flow into and out of populations of concern. By enhancing our understanding of regional biodiversity in this way, natural resource managers are able to make better-informed conservation decisions.

Another primary function of this program is the continued building and maintenance of the Avian Research Collection. This collection represents a permanent record of avian biodiversity that is not only used in many contemporary studies, but also will be available for use by future generations of researchers.
