The Bobolink (Dolichonyx oryzivorus) is a regular summer visitant to southern Canada. In British Columbia, the Bobolink is a regular, but local, summer visitant and breeds in the south-central interior of the province. It inhabits open country, showing a preference for large, established, cultivated hayfields, weedy fields predominated by a mixture of tall grasses, and moist meadows. Very little is known about the breeding biology, ecology, and specific threats to Bobolinks in British Columbia. The Bobolink is known to breed at 22 sites in the province. The total provincial population is estimated to be between 500 and 1100 birds. The population appears stable, but loss of suitable habitat through changing agricultural practices and pesticide treatments do pose a threat to this grassland species. The Bobolink should be considered vulnerable in British Columbia and its current ?Blue List? status should be retained.
