NOTES ON THE MAMMALS OF LAKE MAXTNKUCKEE 9 



woods. A little later, toward the last of October, when frosts are 

 frequent and the days are chill, they may be seen only on those 

 days that are bright and sunny, usually sitting in the sun on the 

 root of some old hollow tree, chipping merrily. Still later, as cold 

 days become the rule, only the brightest days tempt them out; 

 then they sit quietly where the sun shines warmest, chipping not 

 at all or only now and then very mildly. 



Following are some of our notebook records: 



1899. October 3, still out and busy gathering food. 1900. 

 October 18 and 19, noisy about and under our cottage; October 22, 

 noted; 24th, one seen going under cottage; 25th, the one belonging 

 to our cottage was quite noisy for a while; 26th, 2yth and 3oth, 

 still out and noisy; November 3, 5, and 6, seen; 27th, seen for last 

 time. 1901. March 20, the one under our cottage came out 

 today and scurried about as lively as ever. October 19-21, very 

 common on Long Point. At least 20 between our cottage and the 

 end of Long Point, all very busy garnering their winter stores, but 

 mixing a good deal of play with their work. 1902. June 19, two 

 seen on Long Point; 22d, one at tip of Point and several elsewhere. 

 1904. October 18, several seen; i9th, on early morning trip around 

 the lake saw only one; November 5, one seen. 1906. September 

 17, several seen on east side; October 5, a few seen; i4th, a great 

 many seen on east side, all chipping merrily; 25th, caught one in 

 trap on Long Point; 3oth, a very bright colored one seen. 1907. 

 September 26, one heard and another seen on east side; 29th, one 

 heard at Walley's birch swamp; October 4, one seen on Long Point 

 filling its pouches with ragweed seeds which it skillfully gleaned 

 from the standing weeds; loth, one seen on Arlington coal bin, 

 and another with very full pouches basking on a rock near the 

 Duenweg cottage. Loud gun shots fired at coots near by did not 

 frighten it; i4th, one heard chucking near the birch swamp. 



In some sections of its habitat the Chipmunk is said to be migra- 

 tory, but our observations lead us to believe it to be non-migratory 

 in Indiana. 



The Chipmunk feeds chiefly upon nuts and seeds of various kinds. 

 In regions where beech trees are found their delicious nuts consti- 

 tute its principal food. Hickory nuts, particularly the thinner 

 shelled species, hazelnuts, acorns and corn are also highly prized.
