Abstract:Individuals killed by predators often are considered to be in poorer physical condition than those not killed, but little work has been done on behavioural differences between the two. We monitored the behaviour, movements and survival of 15 juvenile red squirrels (Tamiasciurus hudsonicus) from the first day of their emergence through late summer to determine behavioural characteristics associated with predation. Individuals which spent relatively less time vigilant, less time resting, and more time in exposed locations were more likely to be depredated. The distance moved by an individual during observation periods was not related to its survival, but individuals that spent relatively more time off their natal territory were more likely to be depredated. Adult red squirrels spent significantly less time in exposed places than juveniles, which may relate to the lower depredation rates experienced by adults.
