Trends in North American small mammals found in common barn-owl (Tyto alba) dietary studies Trends in North American small mammals found in common barn-owl (Tyto alba) dietary studies
Data on mammals were compiled from published studies of common barn-owl (Tyto alba) pellets. Mammalian composition of pellet samples was analyzed within geographic regions in regard to year, mean annual precipitation, latitude, and number of individual mammals in the sample. Percentages of individuals in pellets that were shrews increased whereas the percentages of rodents decreased with...

Reproductive vulnerability: Parental attendance around hatching in roseate (Sterna dougallii) and common (S. hirundo) terns Reproductive vulnerability: Parental attendance around hatching in roseate (Sterna dougallii) and common (S. hirundo) terns
Presence of one or both members of a pair at the nest site during the incubation and early chick stage reduces reproductive losses due to predation and weather stresses. The authors monitored the presence of pair members by the temporary removal of one member of several pairs of Roseate (Sterna dougallii ) and Common (Sterna hirundo ) Terns at nests at Cedar Beach, New York, to determine...

Mammal mortality at Arizona, California, and Nevada gold mines using cyanide extraction Mammal mortality at Arizona, California, and Nevada gold mines using cyanide extraction
Five-hundred nineteen mammals were reported dead at cyanide-extraction gold mines in Arizona [USA], California, and Nevada from 1984 through 1989. Most numerous were rodents (34.9%) and bats (33.7%); 'bat' was the most often reported category among 24 species or species groups. There are an estimated 160 cyanide-extraction gold mines in these three states, and the number is increasing...

Acute toxicity of four anticholinesterase insecticides to American kestrels, eastern screech-owls and northern bobwhites Acute toxicity of four anticholinesterase insecticides to American kestrels, eastern screech-owls and northern bobwhites
American kestrels (Falco sparverius), eastern screech-owls (Otus asio), and northern bobwhites (Colinus virginianus) were given single acute oral doses of four widely diverse anticholinesterase pesticides: EPN, fenthion, carbofuran, and monocrotophos. LD50s, based on birds that died within 5 d of dosage, were computed for each chemical in each species. Sex differences in the sensitivity...

Denali Park wolf studies: Implications for Yellowstone Denali Park wolf studies: Implications for Yellowstone
The Northern Rocky Mountain Wolf Recovery Plan approved by the U.S. Fish and Wildlife Service (1987) recommends re-establishment of wolves (Canis lupus) in Yellowstone National Park. Bills proposing wolf re-establishment in the Park have been introduced into the U.S. House and Senate. However, several questions have been raised about the possible effects of wolf re-establishment on other

Testing the Wildlink activity-detection system on wolves and white-tailed deer Testing the Wildlink activity-detection system on wolves and white-tailed deer
We tested the reliability and predictive capabilities of the activity meter in the new Wildlink Data Acquisition and Recapture System by comparing activity counts with concurrent observations of captive wolf (Canis lupus) and free-ranging white-tailed deer (Odocoileus virginianus) activity. The Wildlink system stores activity data in a computer within a radio collar with which a...

A records system for a captive crane flock A records system for a captive crane flock
Crane record keeping systems have been evolving at the Patuxent Wildlife Research Center (PWRC) since 1966 and at the International Crane Foundation (ICF) since 1974. The system we present here, a hybrid of the two systems, has been reorganized to promote easy access of information and to limit redundancy.
