After the breeding season, they tend to seek out berry-rich areas. They migrate south early in the fall and return to the north late in the spring and have been known to do so in flocks. Behavior Black-headed grosbeaks frequently sing from prominent perches. Both the male and female sing, but have different songs, and both are known to sing from the nest while incubating. When trying to court a female, males fly with their wings and tails spread. They forage in the foliage, on the ground, or in low vegetation and are prominent berry eaters. When feeding the chicks sing to their mother, rustling wings and displaying their yellow under-feathers (see image).
