Cowbirds don't make nests. They leave their eggs in other birds nests who raise Cowbirds young. For the last three days, and the last half of this video they have followed the Yellow-headed Blackbirds to all three feeding locations at Base Camp. Once the majority of the food is gone the Yellow-headed Blackbirds dig deep for food that may have been buried. The Cowbirds follow and as quickly as the Yellow-headed Blackbirds can did the food up they devour it even before the Yellow-headed Blackbirds can get to it.
