 migrants are first noted. In the center of the State, in general, the}' 

 may be looked for near the middle of February, and to become com- 

 mon within the next two weeks. In the northern counties the aver- 

 age arrival is about March 10, a little later in the vicinity of Chicago, 

 and they are common about the 25th of that month. The following 

 are the early and late first appearances of migrants: Brookville, Janu-

 southern Indiana as far north as Greensburg (Shannon) and Green- 

 castle (Earlle). The most general distribution of Robins in winter 

 occurred the past winter (1896-7). That year they were found 

 throughout Indiana into northern Illinois and southern Michigan. 

 They were reported from Hanover (Culbertson), on the Ohio River; 

 from Greensburg. where a flock of flve hundred was seen December
