 not think there is the slightest doubt of its breeding in this 

 vicinity. Departs for the south in August and September."

*The western birds have recently (Auk, iv, April, 1887, p. 145,) been separated by Mi-. 

 Brewster as S. semipalmata inornaia. This form occurs in Illinois, but whether the true 

 S. semipalmata does also, I am not at present able to state.
