摘要
The Coyote (Canis latrans) arrived on the Gaspe peninsula in the mid 1970s. The population increased through 1990 followed by a general decline. We compared summer food habits of the Coyote in 1988 and 1991 in central Gaspe peninsula, a forested area dominated by conifers. We analyzed 231 seats in 1988 and 435 seats in 1991 to determine Coyote food habits. In 1991, we also marked seven Coyotes with radio-collars and a radioactive isotope (Zn-65) to estimate population density in the study area. The density estimate of 0.2 - 0.3 Coyote/10 km(2) (+/- 35 - 36%) was among the lowest ever recorded. Woodchuck (Marmota monax) and White-tailed Deer (Odocoileus virginianus) dominated the diet in May-June 1988 but were replaced by Moose (Alces alces), Snowshoe Hares (Lepus americanus) and Beavers (Castor canadensis) in 1991. Berries were preferred in mid-summer and comprised 56% and 80% of the volume of seats in August of 1988 and 1991, respectively. The use of small mammals remained relatively constant during both years; i.e., 9 - 19% of seat volume. Results are related to levels of prey abundance on the Gaspe peninsula.
