Management of Pacific brant: Population structure and conservation issues

Pacific brant (Branta bernicla) nest from the Yukon-Kuskokwim (Y-) Delta in southwestern Alaska along the coast of North America to the central Canadian arctic (Pacific Flyway Subcommittee on Pacific Brant 1992) (Figure 1). Birds from this population also nest in the Canadian arctic islands south of Prince Patrick Island and on the coast of the Chukotka Peninsula. Brant nest principally in colonies associated with productive river deltas but isolated nests and small aggregations are common, especially in the arctic. Most Pacific brant breed on the Y-K Delta (Sediger et al. 1993).
