I easily relocated the Blue-winged Warbler this afternoon at Welchester Tree Park (Jeff Co) at the previously noted location on the northeast side of the park, however he was singing a mostly Golden-winged Warbler song the entire 15 min I watched him (or was in range of him). He only sang the last 3 notes of the "Bee buzz buzz buzz" of the Golden-winged Warbler song. Although he is phenotypically a Blue-winged, I'm sure he has some Golden-winged genes in him. The species regularly hybridize where they overlap and I've seen both species sing a spot on song of the other species in Tennessee (where both breed and there is occasional hybridization). I've mostly seen Golden-winged sing a perfect Blue-winged song and have only seen 1 or 2 Blue-winged's sing a Golden-winged song. He's still a Blue-winged, but I doubt he's a pure bird. I need to go back and get a recording of this guy!
