Comparison of capture-recapture and visual count indices of prairie dog densities in black-footed ferret habitat Comparison of capture-recapture and visual count indices of prairie dog densities in black-footed ferret habitat
Black-footed ferrets (Mustela nigripes) are dependent on prairie dogs (Cynomys spp.) for food and on their burrows for shelter and rearing young. A stable prairie dog population may therefore be the most important factor determining the survival of ferrets. A rapid method of determining prairie dog density would be useful for assessing prairie dog density in colonies currently occupied...

Activity of radio-tagged black-footed ferrets Activity of radio-tagged black-footed ferrets
Activity of two radio-tagged black-footed ferrets (Mustela nigripes) was investigated during October-November 1981 (an adult male monitored for 16 days), and during August-November 1982 (a young female monitored for 101 days). Aboveground activity of the male averaged 2.95 hr/night, 15% of the total time monitored. From 22 September to 5 November, aboveground activity of the female...
