Field Testing of Commercially Manufactured Capture Collars on White-Tailed Deer

Predicting energy expenditure of caribou using activity counts: potential use in disturbance studies

“…Similar problems have been documented when using standard radio telemetry (Gillingham & Bunnell, 1985). Kunkel et al (1990) found that the Wildlink activity monitoring system may be used to re- liably achieve estimates of energy budgets. The use of Wildlink AC for monitoring caribou activity and response to disturbance is also promising.…”

“…A programmable radio collar introduced by Wildlink Inc. (MN) records mercury tilt switch counts (AC) in each of 36 intervals of equal length (Note: the collars have since been upgraded and have a year of memory and battery life). A triggering transmitter enables remote programming of interval length and downloading of data (Kunkel et al 1991;Mech et al 1990). Counts collected in an interval correspond to the activity that took place in that interval (e.g.…”
