Changes in productivity and contaminants in bald eagles nesting along the lower Columbia River, USA.
Previous studies documented poor productivity of bald eagles (Haliaeetus leucocephalus) in the lower Columbia River (LCR), USA, and elevated p,p'-dichlorodiphenyldichloroethylene (DDE), polychlorinated biphenyls (PCBs), dioxins, and furans in eagle eggs. From 1994 to 1995, we collected partially incubated eggs at 19 of 43 occupied territories along the LCR and compared productivity and egg cont...

متن کاملLeucocytozoonosis in nestling bald eagles in Michigan and Minnesota.
Thirteen of 21 nestling bald eagles (Haliaeetus leucocephalus) examined for blood parasites in Michigan and Minnesota (USA) during June and July 1997 had patent infections of Leucocytozoon toddi. No other parasites were seen. The degree of parasitemia was light and varied from 1 to 2 on the Ashford Scale. Several of the infected nestlings appeared to have elevated levels of heterophils in their...
متن کاملA model to predict the likelihood of cliff swallow nesting on highway structures in northern California
Cliff swallows (Petrochelidon pyrrhonota) are colonially breeding migratory birds that frequently nest on highway structures. Under the Migratory Bird Treaty Act of 1918, people cannot harm swallows or their active nests. This restriction causes problems and delays for construction and maintenance divisions of many departments of transportation. In planning future projects, it would be useful f...
متن کاملTime Budgets and Behavior of Nesting Bald
Time budgets for adult Bald Eagle (Haliaeetus leucocephalus) activities at nests were documented from mid-incubation to fledging at one nest and from hatching into the postfledging period at two nests. Time-lapse cameras recorded instantaneous samples of activity at 90 second intervals. Both sexes incubated eggs and brooded young. Eggs were incubated for 95% of daylight hours, with the female a...
