The researchers studied grassland breeding bird populations and habitat preferences at Fort Drum, Jefferson County, New York during the 2011 breeding season. In the past, Fort Drum and surrounding areas in Jefferson County have supported large numbers of obligate grassland breeding birds. However, study results when combined with data from past studies of grassland birds at Fort Drum, suggest that habitat specialists such as the sedge wren (Cistothorus platensis) and Henslows sparrow (Ammodramus henslowii) have been continually declining. Reasons for the decline are most likely related to habitat loss due to succession. In 2012, the researcher plans to continue monitoring grassland bird abundance and their habitat selection. Preliminary results suggest that abundances can be expected to continue to decrease as this successional trajectory continues.
