From Chicago to Cape Breton: human-coyote conflict From Chicago to Cape Breton: the expanding ecological envelope of the coyote and patterns of human-coyote conflict


The coyote has more than doubled its range across North America in the last 100 years, making it one of the most provocative wildlife stories in recent years. As coyotes have increased in abundance, they have continued to colonize novel habitats and expand their ecological niche. We have monitored the coyote population as it has colonized the Chicago Metropolitan Area (CMA), one of the largest such areas in the U.S. In a heavily urbanized environment with abundant subsidies, coyote space use declines in area, and survival and reproductive rates increase, creating high densities. Diet analysis shows the key to population success in the CMA is individual variation in resource use, with a minority exploiting anthropogenic resources. Consequently, few coyote-human conflicts occur in the CMA despite thousands of coyotes living among millions of people. In Cape Breton Highlands, Nova Scotia, coyote-human conflicts are extreme, despite the relatively low numbers of coyotes and humans in the area. In this system, coyote space use, reproduction, and density reflects limited resources, and diet analysis revealed a nearly complete reliance on moose, with little inter- or intra-individual variation. The lack of resources, potential predation of a single large ungulate species, and challenging environment may contribute to extreme conflicts. The pathways to attacks on people have become more variable as the coyote has expanded its ecological envelope.
