Gray Wolf (Canis Lupus) Movements And Behavior Around A Kill Site And Implications For Gps Collar Studies, L. David Mech
Gray Wolf (Canis Lupus) Movements And Behavior Around A Kill Site And Implications For Gps Collar Studies, L. David Mech
USGS Northern Prairie Wildlife Research Center
Global Positioning System (GPS) radio-collars are increasingly used to estimate Gray Wolf (Canis lupus) kill rates. In interpreting results from this technology, researchers make various assumptions about wolf behavior around kills, yet no detailed description of this behavior has been published. This article describes the behavior of six wolves in an area of constant daylight during 30 hours, from when the pack killed a Muskox (Ovibos moschatus) calf and yearling on Ellesmere Island, Nunavut, Canada, to when they abandoned the kill remains. Although this is only a single incident, it demonstrates one possible scenario of pack …
Problems With Studying Wolf Predation On Small Prey In Summer Via Global Positioning System Collars, Vicente Palacios, L. David Mech
Problems With Studying Wolf Predation On Small Prey In Summer Via Global Positioning System Collars, Vicente Palacios, L. David Mech
USGS Northern Prairie Wildlife Research Center
We attempted to study predation on various-sized prey by a male and female wolf (Canis lupus) with global positioning system (GPS) collars programmed to acquire locations every 10 min in the Superior National Forest of Minnesota. During May to August 2007, we investigated 147 clusters of locations (31% of the total) and found evidence of predation on a white-tailed deer (Odocoileus virginianus) fawn and yearling, a beaver (Castor canadensis), ruffed grouse (Bonasa umbellus), and fisher (Martes pennanti) and scavenging on a road-killed deer and other carrion. However, we missed finding …
