Mortality of Deer Mice, Peromyscus maniculatus, in Wire Mesh Live-Traps: A Cautionary Note

Thomas S. Jung, Kieran S. O'Donovan

Abstract


Live-capture of animals occasionally results in the death of some individuals. Here, we report upon an unusual occurrence of trap-related mortality observed in Deer Mice (Peromyscus maniculatus) captured in wire mesh live-traps during field sampling in southeastern Yukon. Eight of 85 marked individuals (9.4%) were found with their snouts caught in the wire mesh of our live-traps; four of these individuals were found dead. We suggest a modification to Ugglan live-traps that would likely decrease such incidents.
