Common Chipmunk 



363 



A captive specimen which I kept (also at Toronto) was 

 active all winter when in a warm room; but as soon as exposed 

 to a temperature near freezing point, he curled up in his sleeping 

 place and took no further interest in the affairs of life. 



Many observations testify that a spell of bright warm 

 weather in mid-winter will tempt the Chipmunks forth, and if, 

 as happens in the Southern States, the winter should pass with- 

 out sharp or continuous frost, the Chipmunks probably do not 

 find it worth while to go into the long sleep at all.
