The Black-headed Grosbeak, Pheucticus melanocephalus, is a medium-size seed-eating bird in the same family as the Northern Cardinal, the Cardinalidae. It is sometimes considered conspecific with the Rose-breasted Grosbeak, P. ludovicianus, with which it hybridises on the Great Plains. The 19 cm long, 47 g weight Black-headed Grosbeak is a migratory bird, with nesting grounds from southwestern British Columbia, through the western half of the United States, into central Mexico. It occurs as an accidental further south in Central America.
