Acanthocephala of the bald eagle (Haliaeetus leucocephalus) in North America.

Parasites of the bald eagle (Haliaeetus leucocephalus) of North America.

Information concerning parasites of the bald eagle (Haliaeetus leucocephalus) in North America is relatively sparse. Since the bald eagle in parts of the United States is an endangered species, collection of eagles for parasito!ogical study is difficult. There have been several singular reports of parasites found in oron bald eagles in the literature. However, Kocan and Locke (1974, J. Wild!. I...

To migrate, stay put, or wander? Varied movement strategies in bald eagles (Haliaeetus leucocephalus)

BACKGROUND Quantifying individual variability in movement behavior is critical to understanding population-level patterns in animals. Here, we explore intraspecific variation in movement strategies of bald eagles (Haliaeetus leucocephalus) in the north Pacific, where there is high spatiotemporal resource variability. We tracked 28 bald eagles (five immature, 23 adult) using GPS transmitters bet...

A review of factors affecting productivity of bald eagles in the Great Lakes region: implications for recovery.

The bald eagle (Haliaeetus leucocephalus) population in North America declined greatly after World War II due primarily to the eggshell thinning effects of p,p'-DDE, a biodegradation product of DDT. After the banning of DDT in the United States and Canada during the early 1970s, the bald eagle population started to increase. However, this population recovery has not been uniform. Eagles nesting...

A Review of Modern Bald Eagle (Haliaeetus leucocephalus) Nesting Records and Breeding Status in Nebraska

Distribution and Population Status of Bald Eagles (Haliaeetus leucocephalus) in Interior Alaska

We summarize information available on natural history, numbers, distribution, and status of bald eagles (Haliaeetus leucocephalus) in six regions of interior Alaska: Upper Yukon, Lower Yukon, Tanana, Kuskokwim, Susitna, and Upper Copper. We identified 347 nesting territories using information from local researchers, a raptor nest atlas, unpublished raptor survey reports, and our own surveys. Ne...
