While the typical song is still predominantly what he is singing, just like last year, the Prairie Warbler at the Scuppernong Ski Trails in Waukesha Co. has begun to add various elements of Black-thr Green Warbler (which are common at these trails) song into his personal repertoire! I listened to him alter his song as he sang & foraged above me early this morning. The song is always at least a little "off", if not noticeably different. Would be interested to learn if others have heard this yet?
