An adult yellow-throated warbler (Dendroica dominica) was observed feeding a fledged brown-headed cowbird (Molothrus ater) on July 1, 2010 at the Beehive Overlook at Starved Rock State Park (LaSalle County, Illinois, USA). Food in the form of captured insects was brought to the young cowbird five times during a period of approximately 15 minutes.
