Juvenile Brown-headed Cowbird Begging from a Savannah Sparrow

(Molothrus ater and Passerculus sandwichensis)


Cowbirds lay their eggs in other birds' nests. When the eggs hatch the other birds raise the cowbird chicks as their own. The Savannah Sparrow is likely the Brown-headed Cowbird's surrogate parent.
