and fall. That both forms occur is certain, as there is one speci- 

 men of salicicola taken at Charleston, Mo., May 9, 1879, in the 

 Bryant collection at Cambridge, Mass., and others have been 

 taken in eastern as well as western Iowa and in northern Ill- 

 inois. Without having the bird in hand it is difficult, though 

 not impossible, to tell the subspecies, and it is for this reason 

 that it will be the work of future collectors in our state to de- 

 fine their status. Mr. Chas. K. Worthen says salicicola is the 

 commoner one at Warsaw, 111. 



In Missouri a regular, but nowhere numerous, transient 

 visitant, scattered over the entire state and through a whole 

 month in spring and in fall, from April 20 to May 24, and from 

 September 4 to October 10, but most common from May 10 

 to 17 and from about September 9 to 12 (Earliest April 20. 

 1902, Jasper; latest October 10, 1904, Monteer; both reported 

 by W. G. Savage).

Turdus aliciae. Turdus swainsoni aliciae. Turdus ustulatun aliciae. Alice's 

 Thrush. 



Geog. Dist. — Eastern North America to the Arctic coast, 

 Alaska and eastern Siberia. Breeds far north and migrates 

 through eastern United States, chiefly the Mississippi Valley, 

 to Costa Rica. 



In Missouri one of our common and most regular transient 

 visitants spring and fall, less common westward. The van- 

 guard arrives in southern Missouri in the last week of April: 

 at St. Louis about the first of May, and the bulk is present 

 during the second and third week of May; "lasts" are generally 

 recorded in the fourth week, but individuals have been found 

 fingering into June, even in the southeastern corner of the state, 

 where the ripening of the Mulberries, of which they are very 

 fond, accounts for the delay. They are generaUy in company 

 with Olive-backed Thrushes and with them visit in spring all 

 kinds of places, coming even into gardens in towns and on the 

 lawns in cities. They are often heard to sing at half voice, are 

 very confiding and remain at the same place several days, in 

 cool weather a week or more. In fafi they frequent other localities, 

 chiefly the timber in the bottomlands, where they find difi'erent 

 kinds of berries and thick shelter for roosts. They are sometunes 

 found quite early in September, but the bulk is present in the
