Birding at the Fox River Sanctuary yesterday in Waukesha Wisconsin I came across a couple Blue-gray Gnatcatchers. These birds were present along with many Yellow-rumped Warlbers that were there coming through. They continued to move through the trees and brush searching and getting insects for food.
