I recently did some birding at the Fox River Parkway South in Waukesha Wisconsin. There where numerous White-throated Sparrows present with nice views. A flock of approximately 6-12 birds at different times moved around the woods while I was there. The sparrows scratched the ground finding seeds to eat that have worked their way under leaves and surface ground cover over the winter. Photographs taken on April 29, 2014.
