Abstract
A female Brown-headed Cowbird (Molothrus ater) apparently removed all nestlings from a Blue-gray Gnatcatcher (Polioptila caerulea) nest, des pite attacks by the parents. The nestlings were not eaten; two were dr opped below the nest and a third was carried 15 m and dropped. This is at least the fourth report of Cowbird removal of nestlings of a host species.
