Investigating the Henslow's Sparrow Population Status and Habitat Preferences Within New York State.

The Henslow's Sparrow (Ammodramus henslowii) is one of the most threatened grassland bird species in North America. It has been listed as endangered, threatened, or a species of concern in 16 states and has been included on the National Audubon Society's Blue List as a species of Special Concern since 1974. In New York State it now is restricted to a few areas, and in fewer numbers than were present in the 1960's. The largest concentrations in New York currently reside in Jefferson County, NY, within the St. Lawrence Valley, particularly on the Ft. Drum military base. Declining population trends in the Northeast are likely due to habitat loss. During the initial field season, field assistants and the researcher conducted point count and vegetation surveys on Fort Drum to establish abundance data and habitat preferences to ultimately create a management plan for the Henslow's Sparrow. This first field season showed a decrease in singing males from the previous breeding season at Fort Drum.
