During summer and fall of 2010, we live-trapped 10 adult (> 300 g) pygmy rabbits (five females, five males) from three sagebrush-dominated sites in Idaho, USA, including Magic Valley (43[degrees]3'N, 114[degrees]8'W), Raft River Valley (42[degrees]8'N, 115[degrees]8'W) and Lemhi Valley (45[degrees]2'N, 113[degrees]8'W).
Given the rural setting of the research facility, unquantified, but confirmed evidence of great-horned owls Bubo vigrinianus and diurnal raptors suggests that pygmy rabbits were exposed to random and unavoidable auditory predator cues.
To examine the response of pygmy rabbits to risks of PSMs and predation, we conducted three risk trials that measured food intake under different types of risk.
The Columbia Basin pygmy rabbit is a distinct population of native rabbit that once occupied Douglas, Grant, Lincoln, Adams, and Benton counties in central Washington.
In the spring of 2001, the Washington Department of Fish and Wildlife began a captive breeding program for the Columbia Basin pygmy rabbit to provide animals for release into the wild to augment the natural population.
