difference in the records during the coldest part of the winter— 
in February. That month had only 15 records, while in December 
there were 26, and in January 25, making a total of 66. 
These Woodpeckers confine themselves, in winter, entirely 
to oak groves, where they fly about, mostly in the morning. The 
range of their utterance is very limited, and frequently their pres- 
ence would not be noted unless this utterance was heard. Both the 
old birds and their young are indistinguishable in winter. 
The White-breasted Nuthatch was fairly conspicuous both 
in December and January, the former month totalling 21 and the 
latter 19 records. In February there was a marked falling off— 
only on ten days was the bird seen. Although there was a scarcity 
of the species in February, yet no longer interval than 4 days 
indicates there was no winter migration this season. For the 
three months, there was a total of 50 records. 
The Downy Woodpecker was seen 15 times in December, 
with a long absence between the first and twelfth of the month. 
In January the species had its smallest record for the winter— 
12 observations; with the greatest interval, 4 days. The February 
records amounted to 14, and the longest absence was 3 days. 
The total for the entire month reached 41 records, exceeding the 
winter before by 27 records. 
The Tree Sparrow had its highest record in December—18; 
with the greatest interval, 4 days. January shows 12 observations 
and 6 days as the longest absence. February had but 4 records, 
and a long period of 20 days during which the species must have 
migrated. The total for the winter was 34 records. This was 
the largest number of observations, in winter, that I ever made 
for the Tree Sparrow. Last year.this season shows only 6 records, 
and none at all in December. 
The Snowbird was quite evenly distributed this winter, 
December having 16 records; January, 15; Feb. 14, and the 
total was 45. In December the longest interval was 3 days; in 
January 15 days; in February 2 days. The total number of days 
absent was equal to the total number of days present. The record 
compared with previous winters is phenominal, for in four other 
winters the total was only 60 records. 
The Chickadee was unevenly distributed, December showing 
12 records; Januray 5; and February 7; with a total of 21
