Question

The brown-headed cowbirds lay eggs in other birds' nests. They trick the birds into raising their young. The cowbirds hatch first and push the eggs out of the nest. The cowbirds are then fed by the nest-builder.

Answer 1

Der braunköpfige Cowbird legt Eier in die Neste der anderen Vögel. Sie bringen die Vögel dazu ihre Jungen großzuziehen. Zuerst schlüpfen die Cowbirds und stoßen die anderen Eier aus dem Nest. Die Cowbirds werden dann vom Nestbauer gefüttert.

Answer 2

Cowbirds are brood parasites, which means females lay their eggs in the nests of other birds and let the other mother bird do all of the rearing.
