Different Looking

As we walked through Bidgood Park we spied some birds that migrate through Chicagoland on their way up to their Canadian breeding grounds.  Over the course of the trip we saw about 20 warbler species that spend their summers there and then fly back south through the U.S. in the fall to their wintering grounds.  This Ruby-crowned Kinglet (see a hint of red atop its head) looked unkempt compared to when we see them in breeding plumage in the spring.
