Spring and Summer Birds of Northfield, Minnesota, 1921 
BY J. W. HORNBECK. 
This article forms a second installment of a report on the 
bird life of this locality for one year. The May number of 
THE AMERICAN MIDLAND NATURALIST last year contained an 
article on the fall and winter birds of Northfield, Minnesota, 
1920-21. The latter included 65 species, but the Harris Spar- 
row was omitted by mistake, making a total of 66 different 
species for fall and winter. The present report includes 122 
different species for Spring and summer of the same year. In 
comparing these figures, however, it should be kept in mind 
that the winter of 1920-21 was extremely mild and conse- 
quently brought to us an exceptionally small number of visi- 
tors from the North. For example, my records for fall and 
winter, 1921-22, contain the following nine species which were 
not observed the previous year: Snow Bunting, Purple Finch, 
Cooper’s Hawk, Marsh Hawk, Red-breasted Nuthatch, Red- 
poll, Savanna Sparrow, and Bohemian Waxwing. 
In column 6 of the table which follows, the date when last 
seen is given only for migrants; i. e., for those species which 
go farther north to nest. If they nest in this part of the state, 
they are listed as S. R. for summer resident, or P. R. for 
permanent resident. Summer residents go south for the win- 
ter, while permanent residents are those which are found here 
throughout the year.
