Mercury in bald eagle nestlings from South Carolina, USA.
Bald eagles (Haliaeetus leucocephalus) may be at risk from contaminants in their diet and young birds may be particularly sensitive to contaminant exposure. To evaluate potential risks from dietary mercury exposure to eagle nestlings in South Carolina (USA), we surveyed mercury concentrations in 34 nestlings over two breeding seasons (1998 and 1999). Samples were also obtained from several post...
متن کاملMercury patterns in wood duck eggs from a contaminated reservoir in South Carolina, USA.
Mercury contamination of wildlife populations has been documented widely in recent years as biomonitoring has become an important tool for assessing environmental contamination. Avian eggs provide an ideal assay material for Hg biomonitoring, particularly when the collection of eggs is simplified by using cavity-nesting species that nest in easily monitored nest boxes. However, studies are need...

متن کاملMICHIGAN WILDLIFE CONTAMINANT TREND MONITORING Nestling Bald Eagle Mercury Report: Spatial Trends
The bald eagle (Haliaeetus leucocephalus) is a widely distributed bird of prey throughout Michigan. It has been extensively studied and is susceptible to the effects of environmental contaminants. As a long-lived apex predator, the species is exposed to the effects of biomagnification, and analysis of tissue samples can produce valuable information about organisms positioned lower in the food c...
متن کاملRegulation of Bald Eagle Reproductive Rates in Southeast Alaska
I examined the influence of food abundance and habitat quality on reproduction of Bald Eagles (Haliaeetus leucocephalus) in the Chilkat Valley, Alaska. The proportion of active nests was greatest and the timing of laying earliest in portions of the study area where food was most abundant. Clutch size was not related to food availability. Offspring survival was higher in breeding areas where foo...
