No attempt will be made to relate the bird life of the past 
winter to any set of weather conditions. While snch a relation- 
ship no doubt existed, one would need to have access to very 
complete and detailed weather records, and the problem would 
then consume a great amount of time. In a general way, how- 
ever, it may be recalled that the winter was a long and continu- * 
ous one, with very few warm spells. Late in December there 
was a slight thaw which melted the snow, only to be frozen 
again into a solid sheet of ice which then remained on the 
ground for at least a couple of months. It may be interesting 
to note that the northern Indians early in the winter predicted a 
mild season, and later on some of the South Dakota farmers 
joined in this prophecy on the basis of seeing musk rats migrat- 
ing from one pond to another in the winter. 
There follows a list of the birds found during the past winter 
with some field observations.
