The Canyon Wren reaches the northern limit of its distribution in the Okanagan and adjacent valleys of south central British Columbia, where it's a year-round resident of rocky slopes below 600 m elevation. However, it was only reported in Canada for the first time in 1909, and was briefly extirpated by bitterly cold weather in January 1969, with none observed again until August 1970 (Cannings et al., 1987). The population has remained present ever since, with some individuals occasionally overwintering as far north as Kamloops (Cannings et al., 1987, National Audubon Society, 2010). There are only approximately 1,800 individuals in Canada, representing less than 0.2% of the global population and a very low degree of responsibility for Canada. Christmas Bird Count data suggest a moderate increase in the Canadian population since 1970 but confidence is medium because of the limited sample size. The national population of Canyon Wren is within its goal range.
