(Apparently missed by the IAS Fall Campout group on the 20th, but I 
believe it was there; a difficult bird to identify. The white rump was 
almost never visible while the bird was on the ground, and the only 
time I saw it fly was when I stoned it.)

and at Evanston earlier in August. Three individuals present here on the
