Nest, of coarse twigs and strips of bark, in coniferous trees. Eggs, four to 

 five, white, distinctly and obscurely spotted with light olive-brown, 112 x -81. 



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, remem- 

 bered 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 E. THOMPSON.
