shares a characteristic alarm-note. It is the first warbler to 

 return to us in fall, having been observed as early as August 12, 

 1887, on the sandy islands in the Mississippi River opposite 

 St. Louis, but it is more common and generally distributed 

 from the end of August to the fourth week in September, when 

 most are gone, but, exceptionally, stragglers have been noted 

 as late as October 17, 1885. In the abnormally cold spring of 

 1907 the species was not noticed at St. Louis before May 9, 

 but it was unusually abundant and full of song from May 16 

 to 22.

In Missouri a common and generally distributed summer 

 resident, more common south of the Missouri River than north 

 of it except along the river bottoms. Near the state line in 

 the southeast, where it is very common, it appears at its breed- 

 ing stands about the middle of March (March 12, 1894), but 

 near St. Louis seldom before April (earliest March 29, 1884), 

 usually between April 4 and 12. Other early dates are Jasper, 

 April i, 1902; Warrensburg, April 1, 1905. Earliest at Keokuk, 

 April 13, 1893. In Shannon Co. Mr. E. S. Woodruff noticed 

 it first March 21, 1907. In fall it retires from its more northern 

 stations in the latter part of September (last at Keokuk, Sep- 

 tember 14, 1893; St. Charles Co., September 27, 1905; St. 

 Louis, September 29, 1885, and October 5, 1906). In DunkHn 

 Co. it was still common and in song early in October, 1896.
