Do shrubland birds prefer shrubland habitat in a highly modified landscape?
Neil Gifford Wednesday, October 15, 2008 – 2:00-2:30 Shrubland birds of the northeastern U.S. are in steep decline and have become the most conservation-reliant avian group in the region. Their contemporary distribution is restricted to pine barrens, regenerating commercial forests, utility rights-of-way, and other types of managed early successional habitat. Most shrubland birds will use small and isolated patches, suggesting some level of resilience and area insensitivity, but will the birds avoid small and isolated patches burdened by severe threats like urbanization, fire suppression, and invasive plants? We tested whether shrubland birds associate preferentially with scarce and fragmented shrubland habitat in a threatened and intensively managed urban-wildland landscape, the 1,250 ha Albany Pine Bush Preserve, NY. During breeding season point counts in 2005 we observed 90 bird species, including 18 shrubland species, 12 of which have experienced significant long-term regional popu
