Rparian Raptors on USACE Projects: Osprey (Pandion haliaetus)

摘要

The osprey (Figure 1) is one of four raptor species included in a series of Engineer Research and Development Center (ERDC) technical notes produced under the Ecosystem Management and Restoration Research Program (EMRRP). These technical' notes (ERDC TN-EMRRP-SI-(l2-l5)) identify riparian species potentially impacted by U.S. Army Corps of Engineers (Corps) reservoir operations. For management purposes, these raptors are considered riparian generalists because they inhabit riparian zones surrounding streams and lakes on Corps project lands but may seasonally use adjacent transitional and upland habitats. The other raptors in this grouping are the bald eagle (Haliaeetus leucocephalus), peregrine falcon (Falco peregnnus), and red-shouldered hawk (Buteo lineatus), each of which is discussed in a technical note describing the ecology, legal status, potential impacts, and management guidelines for the species. These technical notes are products of the EMRRP work unit entitled 'Reservoir Operations Impacts on Habitats of Target Species' and are linked to ERDC TN-EMRRP-SI-11, which describes the function of the work unit and the general status, impacts, recovery, and management of these four riparian raptors on Corps projects.
