260 Trans. Acad. Sci. of St. Louis. 



Breeds from Florida, Louisiana, Arkansas and Indian Territory 

 northward. Winters in Cuba and Guatemala. 



In Missouri a common and generally distributed summer 

 resident in all parts of the state high and low, north and south, 

 east and west. Formerly a true woodland species it has accus- 

 tomed itself to the new conditions and feels at home wherever 

 there are trees, even in cities, often building its nest within a few 

 yards of occupied dwellings. At the southern border, in Dunklin 

 Co., the first Wood-Thrush was heard to sing as early as April 3. 

 At St. Louis and in central Missouri generally, also in the higher 

 parts of southern Missouri, the first are heard to sing between 

 April 18 and 24, at the northern border between April 25 and 

 30. Exceptions are rare, and the bulk is usually present in the 

 last days of April southward and the first week in May northward, 

 when transient individuals swell their numbers and the song of 

 the Wood-Thrush is heard everywhere. Migrants from the north 

 are with us during the first half of September, but the bulk of 

 the species leaves central Missouri about the middle of the month 

 and nearly all are gone before the end of the month, except in 

 the southern part of the state, where some linger through the 

 first decade of October (St. Louis, October 7, 1905; New Haven, 

 October 9, 1903; Jasper, October 10, 1902; Monteer, October 

 10, 1904).

Geog. Dist. — The breeding range of the two subspecies has 

 not yet been clearly defined. While the Wilson's breeds in 

 eastern North America from southern Alleghenies and about 

 40° lat. northward to Nova Scotia and Ontario, the Willow 

 Thrush's summer home is not only in the Rocky Mountains 

 from New Mexico and Arizona north to British Columbia, but 

 reaches eastward through Manitoba and northwestern Ontario, 

 where they are slightly intermediate, to Newfoundland. 



This pecuHar overlapping of the breeding areas must produce 

 a crossing of migration routes, which makes it at present diffi- 

 cult to say to which of the two forms the majority of tran- 

 sients belong that regularly pass through our state in spring
