While studying the habits of birds in the great coniferous forest of 
the north, I soon found that I was very safe in attributing any new 
strange shrieks or wails, whose origin I was otherwise unable to trace, 
to the Canada Jay. Many of the notes resemble those of the Blue Jay, 
but it has a number that are distinctly its own. Some of these are 
musical, but most of them are harsh and discordant. 
In its habits it is much like its blue cousin, but it is less shy, and 
becomes almost tame if allowed to come unmolested about the camp 
for a few days in succession. In form it is like a magnified Chickadee, 
clad in singularly furlike, thick, puffy gray feathers; on its forehead 
is a white spot, the size of a dime, and its wings and tail are of a much 
darker gray than the other parts. This description, remembered in 
conjunction with the habits, will at once identify the species. 
It nests early in March — that is, while deep snow still covers the 
ground and hard frost reigns supreme; and no satisfactory explana- 
tion of this strange habit has yet been brought forward. No doubt 
one or other of the parents always remains with the eggs, but still it 
is difficult to see how they can keep them from freezing when the sur- 
rounding air is chilled to 30° below zero. 
It is a non-migratory species, and it is said that in autumn it pro- 
vides against the annual famine of winter by laying up a store of nuts 
and other food. Ernest Thompson Seton.
