Blue-winged Warbler ...

… with a long stick--nesting material--?  Whatever her* objective, she* dropped it an instant later (see the extra--2 images later in a string of continuous shots :)  Another visit to the Fort River Refuge, again on a superb spring morning.  We are fortunate that Blue-wings nest at Fort River, since they are otherwise uncommon. Here's an image from two years ago.
Added 5/25: * "female, probably a yearling" --comment from my ornithologist friend
