rare at Rockford, 111. It was previously unknown at Oberlin, Ohio, but 

 was found to be not uncommon during the summer of 1894. 



In 1895 reports came from Ontario, Can., announcing the arrival of 

 Dickcissel in considerable numbers. It was also common at Oberlin, 

 and twelve miles north on the south shore of Lake Erie. Mr. J. C. Gal- 

 loway reports it much less common at Montgomery, Ohio, than in the 

 previous year. Mr. R. M. Strong reports that it is becoming more com- 

 mon each year in the vicinity of Milwaukee, Wis. It was in normal 

 numbers in Indiana, Illinois, Iowa, and Missouri during 1895. 



The encroachments of Dickcissel on territory previously unoccupied, 

 seem to be due to an overflow from adjacent regions where it is common, 

 and not a withdrawal from regions where it has been common. The lack 

 of notes relating to the Grasshopper and Henslow's Sparrows makes any 

 suggestion as to their encroachments on new localities impossible. Their 

 sudden appearance in Lorain Co., Ohio, in 1894, remains unexplained. 



The suggestion might be made : " Is it not probable that these species 

 have always occupied the regions where they are now found for the first 

 time, but that they have been entirely overlooked, later and more thorough 

 field work revealing their presence ? " To this I would say that in. the 

 vicinity of Oberlin, Ohio, the actions of the birds seen the first year 

 were very different from the actions of those seen the second year which 

 had nested in the region the previous year. After mating they were 

 restless, flitting about from place to place, confined to no given locality 

 until after the time when they should have been nesting. They finally 

 selected a place for the nest and settled down to the duties of the season. 

 The next year the birds appeared first near their nesting place of the 

 previous year and remained in that vicinity until after the breeding season. 



It may not be genearlly known that the usual summer range of all 

 three of these species is as far north as Minnesota, northern Ohio, to 

 southern New England. They pass the winter in the southern states. 

 They are birds of eastern North America, ranging west to the plains. 



Those who are unacquainted with the Grasshopper and Henslow's 

 Sparrows will do well to read what Mr. Frank M. Chapman says about 

 them in Birds of Eastei-7i North America. A short article by the 

 writer on Grasshopper Sparrow may be found in the Ornithologist's 

 and Ooloffisf s Semi-A7imtal, Vol. i. No. 2, page 8.
