The Herring Gull (Larus argentatus) breeds throughout the interior of British Columbia at 40 or so sites from Okanagan Lake northwest through the Fraser Plateau, Babine Upland, Nass Basin, and the Northern Mountains and Plateau region to Kelsall Lake in Chilkat Pass, and locally east through the Liard Basin to the vicinity of Kotcho Lake northeast of Fort Nelson (Campbell et al. 1990). It nests singly, or in colonies (rarely more than 100 pairs), and all sites are associated with lakes with forested and rocky islands and/or grassy and bare rocky islets. At the southern limit of its range in south-central British Columbia the Herring Gull is known to nest at only two sites; on a bare rocky islet in Okanagan Lake (Cannings et al. 1987) and on a smaller bare rocky islet in Bridge Lake (Munro 1935, Campbell 1968). The elevations at both sites are 342 m and 1, 133 m respectively.
