Cowbirds are nest invaders. They lay their eggs in the nest of other birds and let the unsuspecting parent raise their young. This is called brood parasitism. The cowbird checks nests later to make sure their eggs are being incubated & if their eggs are gone they will destroy the host parent’s eggs or young to ensure this behavior is not passed on to its offspring.
