Fall and Winter Birds of Northfield, Minnesota, 1920 - 1921. 
BY J. W. HORNBECK. 
Northfield is situated about forty miles south of Minneapolis 
and St. Paul. It is a most favorable locality for bird study. The 
Cannon River, which flows through the heart of the city, provides 
timber, thickets, and weed patches, within short walking distance 
to the north and south. On the east the cemetery furnishes eighteen 
acres of pine, spruce, balsam, and other evergreens. Carleton 
College Campus, with its chain of lakes, attracts water birds as 
well as land birds; while St. Olaf College Campus, spreading over 
the hills on the west, harbors species which frequent the open woods. 
The outlying country is a typical dairy-farming region, spotted 
here and there with patches of timber land. 
This report includes the six-months interval from September 
I, 1920 to March 1, 1921. With the two or three exceptions, 
noted in the column of the Table headed ‘‘Remarks,”’ all of the 
records were made within the city limits of Northfield or, at the 
fartherest, within a zone a half-mile wide surrounding the city. 
Observations in town and on Carleton College Campus were re- 
corded daily, and regular trips were made about three times a week. 
The third column of the Table gives the date of migration of a 
number of our summer residents. Since the date, September first, 
is chosen arbitrarily, it will be in the interest of completeness to 
list a few additional species which remainéd late into August, but 
which migrated before the first of September. The date when last 
observed will be given for each species.
