564 REPORT OF STATE GEOLOGIST. 



Rare winter resident and occasional migrant, breeding far to the 

 northward of the United States. One shot from a flock of five near 

 Brookville, February 23, 1885. That morning the thermometer regis- 

 tered 10 degrees below zero. For several mornings previous the 

 weather had been equally severe. The canal, most of the smaller 

 streams, ponds and the rivers, except where there were rapids, were 

 frozen over. In one of these open places the Loons were found. I am 

 informed by Mr. Charles Durj, of Cincinnati, of a specimen that .was 

 killed near Chalmers several years ago. Mr. C. A. Stockbridge reports 

 it as a rare visitor at Ft. Wayne. Mr. Ruthven Deane found one at 

 English Lake, May 4, and another May 11, 1890. Dr. Langdon noted 

 two or three in the vicinity of Cincinnati, and Dr. Wheaton says it is 

 not rare on Lake Erie. Mr. Nelson says it is a very common winter 

 resident upon Lake Michigan. Prof. Cook reports it from Michigan. 

 The Loons subsist chiefly upon fish, and their flesh has a fishy flavor, 

 rendering them unfit for food, although it is said they are eaten by the 

 Indians. They also, while engaged in fishing, are reported to become 

 entangled in the fishermen's nets.
