Description
The larger nestling with the red beak is a cowbird. The smaller yellow-beaked nestlings are Carolina wrens. Cowbirds, the only obligate brood parasites in North America, don't build their own nests. Instead, they generally remove an egg from another species' nest, replace it with one of their own, and then rely on the surrogate parent to incubate the egg and rear the nestling. In this case, the Carolina wren built its nest in a wreath on my front door. My hope is that the wren nestlings will get enough nourishment to live until the cowbird nestling leaves the nest as they mature faster.

very interesting, L

It was recommended I extract the parasite (cowbird) from the nest to ensure survival of the wrens. I am happy to report all 3 wren babies are doing well.
