This morning at about 9:30 there was a Magnolia Warbler in the wooded (and currently swampy) area just south of the soccer fields at Aurora Sorts Park.
I was not able to get photos, but the bright yellow breast and sides with heavy black streaking, and distinctive black tail with lateral, white patches were clear.
