Cowbirds Utilize Fragmented Forests Effectively By

Question

Cowbirds utilize fragmented forests effectively by
A)feeding on the fruits of shrubs that tend to grow at the forest/open-field interface.
B)parasitizing the nests of forest birds, and feeding on open-field insects.
C)roosting in forest trees, and nesting in grassy fields.
D)outcompeting other songbird species in fragmented communities.
E)using forest cover to escape from predators in their normal grassland habitat.

Accepted Answer

Cowbirds are known for their brood parasitism where they lay their eggs in the nests of other songbird species, leaving the host bird to raise the cowbird chick instead of their own offspring. This behavior allows cowbirds to utilize fragmented forests effectively by relying on forest birds for nesting sites and open-field insects for food.
