Philadelphia Vireo, Warbling Vireo, Prothonotary Warbler and more at the Fox River Sanctuary in Waukesha May 19, 2014.

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.

I did a short birding run today of  1 hour at the Fox River Sanctuary in Waukesha Wisconsin early this morning. The Chestnut-sided Warbler gave the best views of the 11 warbler species present. Lower numbers of each compared to a couple of days ago. The other warbler species present were Blackburnian, Palm, Northern Parula, Yellow-rumped, Yellow, Common Yellowthroat, Black-and-white, Magnolia, American Redstart and Wilson’s. It was a fun 1 hour with nice blue skies and mild temps of almost 50 at 8:00 am. Images are of males. Images were taken on May 18, 2014.
