Lead in hawks, falcons and owls downstream from a mining site on the Coeur D'Alene river, Idaho Lead in hawks, falcons and owls downstream from a mining site on the Coeur D'Alene river, Idaho
Mining and smelting at Kellogg-Smelterville, Idaho, resulted in high concentrations of lead in Coeur d'Alene (CDA) River sediments and the floodplain downstream, where American Kestrels (Falco sparverius), Northern Harriers (Circus cyaneus), Red-tailed Hawks (Buteo jamaicensis), Great Horned Owls (Bubo virginianus), and Western Screech-owls (Otus kennicotti) nested. Nestling American...

Two hybrid common x roseate terns fledge at Falkner Island, Connecticut Two hybrid common x roseate terns fledge at Falkner Island, Connecticut
Although these two similarly-sized species are sympatric throughout much of their breeding range, there are few published records of hybridization between Roseate (Sterna dougallii) and Common (S. hirundo) Terns. Records include at least five from Europe (Witherby and Ticehurst 1908, Perry 1972, Robbins 1974, Burggraeve 1977, van den Berg 1980) and only one from North America (Hays 1975)...

The natural history of Caroline Atoll, Southern Line Islands. Part II. Seabirds, other terrestrial animals, and conservation The natural history of Caroline Atoll, Southern Line Islands. Part II. Seabirds, other terrestrial animals, and conservation
conclusion: Lushly wooded Caroline Atoll, with the majority of its 39 islets (399 ha of land) either in near-pristine condition or having recovered remarkably from past disturbance, is one of the least spoiled atolls in the Pacific. Uninhabited, it harbors plant ecosystems and breeding seabirds (Pt. II) of national and international importance. Its marine and terrestrial ecosystems are...

Habitat use by an endangered riverine fish and implications for species protection Habitat use by an endangered riverine fish and implications for species protection
We investigated habitat specificity of the amber darter (Percina antesella Williams & Etnier 1977), an imperiled fish from restricted portions of 2 rivers in the southeastern United States. Foraging amber darters occupied a narrow range of riffle habitat, consistently avoiding areas 20 cm deep and with velocity 10 cm. s-1 near the substrate, occupying areas with cobble or gravel...

Buffer zones of territories of gray wolves as regions of intraspecific strife Buffer zones of territories of gray wolves as regions of intraspecific strife
The locations of 22 territorial gray wolves (Canis lupus) killed by conspecifics in northeastern Minnesota were analyzed in a study involving radio-telemetry from 1968 through 1992. Twenty-three percent of the wolves were killed precisely on the borders of their estimated territories; 41%, within 1.0 km (16% of the radius of their mean-estimated territory) inside or outside the estimated...
