The White-throated Swift (Aeronautes saxatalis), is a breeding summer visitant of south-central British Columbia. Since becoming established near Vaseux Lake in the southern Okanagan early in this century, it has been recorded northwest through the interior plateaus as far as the Chilcotin River. Scattered breeding populations also occur in the Similkameen Valley to the east, and in the Kootenays to the west. Based on existing information, it is estimated that there are ±400 breeding pairs in 56 known sites in the province, two-thirds of which occur in the Okanagan. The species nests in crevices on inaccessible cliffs, making it less susceptible to the development pressures that are threatening other species and their habitats, particularly in the Okanagan portion of its range.
