The Black-headed Grosbeak (Pheucticus melanocephalus) breeds regularly across much of western North America from Oaxaca north to southern British Columbia and from the Pacific coast to central Nebraska (Ortega and Hill 2010). The northern limit of the species’ range has expanded steadily in British Columbia since the 1940s (Campbell et al. 2001, Martell 2015). Here we report the first documented instance of the Black-headed Grosbeak breeding in Alaska.
