I birded the Fox River Sanctuary in Waukesha Wisconsin mid-morning today. Two new species at the river today, the Philadelphia and Warbling Vireos. They gave nice views as they both continually foraged through the trees along the river. The warbler action started out a little slow but then picked up with a total of 12 warbler species. Some of the warbler highlights were a 30 second view of a Prothonotary, Blackburnian, Bay-breasted, Northern Parula and Wilson’s. This place just amazes me! Images were taken on May 19, 2014.
