Nesting Biology of Urban Cooper’s Hawks in Alameda County, California

Autor: Allen M. Fish, Christopher W. Briggs, Ralph V. Pericoli, Emma L. Karsten

Publikováno v: Western Birds. 51:307-317

In recent decades Cooper’s Hawks have successfully colonized urban landscapes, where there may be ample prey but also a greater prevalence of disease in their prey. We searched for nesting Cooper’s Hawks in and around Berkeley, California, from 2

Publikováno v: Ecotoxicology. 28:379-391

We assessed total mercury (THg) concentrations in breast feathers of diurnal North American raptors collected at migration monitoring stations. For 9 species in the Pacific Flyway, we found species and age influenced feather THg concentrations wherea

Secondary Anticoagulant Rodenticide Exposure In Migrating Juvenile Red-Tailed Hawks (Buteo jamaicensis) In Relationship To Body Condition

Autor: Christopher W. Briggs, Joshua M. Hull, Emily V. Abernathy, Allen M. Fish

Publikováno v: Journal of Raptor Research. 52:225-230

Secondary exposure to anticoagulant rodenticides (ARs) through consumption of contaminated prey has been documented worldwide in many non-target species, especially raptors. The Red-tailed Hawk (Buteo jamaicensis), a raptor that frequents agricultura

Differential Migration and Phenology of Adult Red-Tailed Hawks in California

Autor: Joshua M. Hull, Allen M. Fish, Katharine M. Tomalty, Christopher W. Briggs, Angus C. Hull

Publikováno v: Journal of Raptor Research. 50:45-53

Differential migration by age and sex has been observed within several raptor species. Here, we report differential autumn migration timing between adult and juvenile Red-tailed Hawks (Buteo jamaicensis), and between adult males and females at the Go

Fall migration of radio-tagged Broad-winged Hawks (Buteo platypterus) in California

Autor: Angus C. Hull, Alan B. Harper, Phillip J. Capitolo, Lynn J. Jesus, Allen M. Fish

Publikováno v: The Wilson Journal of Ornithology. 132:15

Little is known about migration patterns of Broad-winged Hawks (Buteo platypterus) in the western United States apart from small numbers that have been recorded at migration monitoring sites. To better understand their movements in coastal California

Natal Dispersal Distance and Population Origins of Migrant Red-Tailed Hawks and Cooper's Hawks

Autor: Robert N. Rosenfield, Allen M. Fish, Peter H. Bloom, Angus C. Hull, Jill A. Harley, Joshua M. Hull, Christopher W. Briggs

Publikováno v: Journal of Raptor Research. 54:47

We used a two-step process to determine region of geographic origin for migratory Red-tailed Hawks (Buteo jamaicensis) and Cooper's Hawks (Accipiter cooperii). First, we used encounter data from the USGS Bird Banding Laboratory to estimate natal disp

Examining Sublethal Effects of Anticoagulant Rodenticides on Haemosporidian Parasitemia and Body Condition in Migratory Red-Tailed Hawks

Autor: Emily V. Abernathy, Kristina A. Dudus, Laura A. Kwasnoski, Christopher W. Briggs, Allen M. Fish

Publikováno v: Journal of Raptor Research. 53:402

Anticoagulant rodenticides (ARs) are a source of mortality to nontarget wildlife, including raptors. Raptors that consume a large quantity of rodents, such as Red-tailed Hawks (Buteo jamaicensis), are especially at risk of secondary exposure due to b

Development and testing of a mechanical lure for raptor trapping

Autor: Joshua M. Hull, Allen M. Fish, Craig Nikitas, Angus C. Hull

Publikováno v: Wildlife Society Bulletin. 37:872-876

Raptor trapping and banding at migration stations rely upon the use of live lure birds to attract hawks to the trapping area. The use of these lure animals may present raptor researchers with legislative, regulatory, ethical, and logistical challenge
