A Device To Record The Specific Time An Artificial Nest Is Depredated, Jennifer S. Borgo, Michael R. Conover

Human–Wildlife Interactions

We designed a timing device that records the calendar date and time of a depredation event on an artificial nest. The clock was simple to construct and successful in field trials, with only 6% failure (3 of 48 clocks). The average difference between actual and estimated depredation time was 4.6 minutes. Use of this clock improves daily survival estimates, provides insight into predator activity patterns, and allows the evaluation of investigator-induced depredation.
