Summer Warblers in N. IL: Common Yellowthroat* (Above), Yellow-breasted Chat*, American Redstart*, Louisiana Waterthrush*, Ovenbird*, Northern Parula*, and those with "warbler" ending its names: Blue-winged, Yellow*, Chestnut-sided, Cerulean*, Pine*, Prairie, Yellow-throated*, Black & White*, Prothonotary*, Kentucky, Worm-eating*, Mourning, and Hooded*. Obviously birds do not read the field guides to tell them where they should be in certain times of the year, so boundaries and territories are flexible. Warblers that I have seen in the summer in the Rockford area which are not listed in Sibley's as summer residents are: Tennessee, Nashville, and Black-throated Green. Of this list, I have seen 14 of them (marked above with an *), however, not all of them marked with the * have I seen in the Northern Illinois area. It just means I have seen them in other states (i.e. the Worm-eating and Hooded Warblers I saw in the Smoky Mt. Nat Park, but have yet to see them in Illinois). The 5 Warblers that have avoided my camera's viewfinder are the Blue-winged, Chestnut-sided, Prairie, Kentucky, and Mourning Warblers.
