Bobolinks are small members of the blackbird familiy. The adults are from 16-18cm (6-8 in) long. males are mostly black and white but they do have a creamy patch on the back of their head and neck. Females are mostly brown with black streaks on their back and sides. Their wings and tails are darker.
Bobolinks eat mostlyseeds and insects which they get on or near the ground.
They like to nest in in open, grassy ground. Females lay 5-6 eggs in a cup shaped nest.
Bobolinks migrate to South America in large flocks. They like to eat grains and rice when they travel and in someplaces are called "Ricebirds". In Jamaica they are called "Butterbirds" becasue they get quite fat when they migrate and the Jamaicans gather them for food.
