H. B. A., Gibbon, Neb., writes:
"While out for a walk this season I discovered the nest of an American Goldfinch placed in a crotch of an apple tree. In this nest, which was built as usual, I found first the bottom an egg of the Cowbird, over this a heavy lining, and on this a set of the Goldfinch. I allowed these to remain. Those of the Goldfinch were incubated, but that of the Cowbird did not, probably due to unusual amount of lining."
