A GIS and Remote Sensing Based Analysis of Impervious Surface Influences on Bald Eagle (Haliaeetus leucocephalus) Nest Presence in the Virginia Portion of the Chesapeake Bay
GIS (Geographic Information Systems) and remote sensing techniques were used to predict relationships between bald eagle nest presences and land type, distance to land type and impervious surface cover area. Data plots revealed bald eagle nest presence decreases in response to an increase in area …

Bald eagle distribution, abundance, roost use and response to human activity on the northern Chesapeake Bay, Maryland
I studied bald eagle (Haliaeetus leucocephalus) distribution, abundance, roost use and response to human activity on the northern Chesapeake Bay from 1984-89. The eagle population consisted of Chesapeake breeding eagles, Chesapeake nonbreeding eagles, northern-origin eagles and southern-origin …

The Impact of Wind Turbines on the Distribution of Wintering and Migrating Raptors
… Harrier (Circus hudsonicus), Bald Eagle (Haliaeetus leucocephalus), Red-tailed Hawk (Buteo jamaicensis), Rough-legged Hawk (Buteo lagopus), Snowy Owl (Bubo scandiacus), or American Kestrel (Falco sparverius) – changed their distributions in response to wind turbines. Similarly, we found no …

A Comparison of the Pectoral Spines in Virginia Catfishes
… determination of catfishes eaten by bald eagles (Haliaeetus leucocephalus) using spines collected near their nests. Bald eagles ate blue catfish (60%), channel catfish (27%), white catfish (9%), brown bullheads (4%) and yellow bullheads (0.5%). Madtom and flathead catfish were not consumed. Mean …

The influence of perch tree distribution and abundance on bald eagle distribution on the northern Chesapeake Bay, Maryland
… is important perching habitat for bald eagles (Haliaeetus leucocephalus). Bald eagles hunt, feed and loaf on shoreline perches. I measured trees suitable for bald eagle perches along the northern Chesapeake Bay during 1990-1991 to determine the influence of shoreline perch tree availability on …

Re-Establishing Bald Eagle and Osprey Breeding Populations in South Dakota Through Hacking: A Feasibility Study
Bald eagles (Haliaeetus leucocephalus) and ospreys (Pandion haliaetus) historically nested in South Dakota, but until 1991 neither species had nested in the state for > 100 years. In 1991, an osprey pair nested in the Black Hills near Pactola Reservoir, and in 1993, a bald eagle pair nested along …

Foraging ecology of bald eagles on the northern Chesapeake Bay with an examination of techniques used in the study of bald eagle food habits
… food habits of nonbreeding bald eagles (<i>Haliaeetus leucocephalus</i>) on the northern Chesapeake Bay, as a preliminary step toward examining food-base effects on bald eagle distribution and abundance. To correctly interpret our food habits results, we first examined biases of 2 …

Effects of food on bald eagle distribution and abundance on the northern Chesapeake Bay: an experimental approach
Availability of dead fish to bald eagles (Haliaeetus leucocephalus), prey preferences of bald eagles, and the effects of food on their distribution and movements on the northern Chesapeake Bay were examined from April 1988-July 1989. Dead fish surveys were conducted, by boat, to monitor dead fish …
