BIRDS OF MINNESOTA. 425 
After a long period of crisping cold -days has softened into 
one less rigorous ‘‘Nuttie,” and his cousin will put in a joint 
appearance. Then his monotonous cha-cha-cha-cha will sound 
as cheery as more varied notes in the sunny season of song 
would, but his visits are not frequent in winter in this latitude; 
nor are they prolonged, for when he has dropped, head down- 
wards, onto the trunk of the leafless tree, and begun his search 
for larvae and insects, it is not long before every considerable 
portion of the tree has been searched, and he has bounded 
away to another. It rarely lights on the ground, and then it 
remains but a few moments at most. 
In proportion to its size, it is capable of vieing with the 
woodpeckers in the use of its bill to excavate a hole in a tree 
for its nest, which is sometimes sunken 14 to 18 inches below 
the point of entrance. It lays5 eggs usually, of a pearly-white 
color, touched sparingly with dark-greenish, or dirty- yellow. 
The young are brought out early in June. I have not met with 
more than one brood to a pair in the same season, and from the 
uniformity of the development of the young in the early autumn, 
I believe it to be their local habit to rear but the one, whatever 
may have been observed otherwheres. Under what circum- 
stances they brave the severity of the winters in Minnesota can 
only be conjectured, but, presumably, in holes of trees in the 
swamps where evergreens afford protection from the winds. 
For the species, they may be regarded as abundant in nearly 
all wooded portions of the State, and much more frequently 
seen in spring and fall than during either summer or winter. 
Mr. Grant found them in St. Louis county during the summer, 
Dr. Hvoslef at Lanesboro in March, Kennicott at Lake of the 
Woods on May 31st, and Mr. Washburn everywhere in the Red 
river region in both summer and autumn in abundance.
