Populations and Prey Selection of Wintering Raptors in Boulder County, Colorado

Wintering raptor populations were monitored between 1983 and 1988 in a 35 km2 study area centered 8 km north-northeast of the city of Boulder, Colorado. Raptors congregated around active prairie dog (Cynomys sp.) colonies. Golden eagles (Aquila chrysaetos) , ferruginous hawks (Buteo regalis), and red-tailed hawks (Buteo jamaicensis ) were observed hunting and capturing prairie dogs. Bald eagles...

Climate, soils, and connectivity predict plague epizootics in black-tailed prairie dogs (Cynomys ludovicianus)

Outbreaks of plague in wildlife are sporadic and spatially dispersed, and they depend on coincidence of susceptible hosts, flea vectors, the plague bacterium (Yersinia pestis), and environmental factors that support pathogen transmission. We fit spatial models of plague outbreaks to a long-term data set (1981–2005) of towns of black-tailed prairie dogs (Cynomys ludovicianus) on the shortgrass s...

Dynamics of plague in a Gunnison's prairie dog colony complex from New Mexico.

A plague (Yersinia pestis) epizootic spread through Gunnison's prairie dogs (Cynomys gunnisoni), and possibly other rodent species, in the Moreno Valley in north-central New Mexico between winter 1984-1985 and autumn 1987. We observed the progress of the epizootic and subsequent population recovery at four prairie dog towns within the valley during this period. At two towns (Midlake and Val Ver...

Comparisons of Strychnine and Zinc Phosphide in Prairie Dog Control

Efficacy and safety are primary considerations in registration and use of toxicants for vertebrate pest controlo Strychnine (0,5$) and zinc phosphide (2$) are currently registered by EPA for prairie dog control, but continued registration is uncertain. Two percent zinc phosphide bait has been suspected of producing lower and more erratic results than strychnine baito In our study in western Neb...
