In western North America, the sweet song of the Black-headed Grosbeak caroling down from the treetops sounds like a tipsy robin welcoming spring. The flashy black, white, and cinnamon males and the less flamboyant females sing from perches in suburbs, desert thickets, and mountain forests. At feeders they effortlessly shuck sunflower seeds with their heavy bills. The showy male puts in equal time on the domestic front: both sexes sit on the eggs, feed the young, and feistily defend their nesting territory.
