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.
