In southern Indiana the Northern Shrike is usually an irregular, 

 rare winter visitor, though occasionally it is found in some numbers. 

 Northward it is a tolerably common winter resident. It arrives from 

 November 1 to 15, and remains an indefinite time, its length per- 

 haps determined by the food supply. It sometimes leaves in Jan- 

 uary or February and occasionally remains until the middle of 

 March. The spring dates are very uncertain. The Loggerhead Shrike 

 is an early migrant and is often mistaken for this species. While 

 some rare and obscure birds are carefully noted, and concerning 

 them we have good reports; of other birds that are quite conspicuous, 

 we lack accurate information. It would be of value to have observa- 

 tions that shall distinguish between the Shrikes and give full infor- 

 mation concerning the standing of each. The winter of 1880-81 this 

 species was quite common at Brookville. The winter of 1885-6 it was 

 numerous about Chicago, HI.
