NORTH AMERICAN BIRDS EGGS. 



484b. Alaskan Jay. Perisoreus canadensis fumifrons. 



Range. Alaska. 



A very similar bird to the Canada Jay but with the forehead yeliowish'or dull- 

 er; the nests and eggs are like those of the others of the genus. 



484c. Labrador Jay. Perisoreus canadensis nigricapillus. 



Range. Labrador. 



This is a darker variety of the Canada Jay. 

 from those of any of the others of the genus. 



Its eggs cannot be distinguished 



485. Oregon Jay. Perisoreus obscurus 



Range. Mountain ranges from northern California to British Columbia. 



These birds are very similar to canadensis but have the whole underparts 

 white. Like the Canada Jays they appear to be wholly fearless and pay little or 

 no attention to the presence of mankind. Their nesting habits and eggs are 

 the same as the preceding except that they have generally been found nesting 

 near the tops of tall fir trees. Size of eggs, 1.05 x .80. 



485a. Gray Jay. Perisoreus obscurus griseus. 



Range. British Columbia to northern California, east of the coast ranges. 

 This bird is said to be larger and grayer than the preceding. 



486. American Raven. Corvus corax sinuatus. 



Range. North America west of the Rockies and from British Columbia 

 southward. 



The Raven is like a very large Crow, 

 length 24 inches, but has the feathers 

 on the neck lengthened and stiffened. 

 Their habits are similar to those of the 

 Crow, but more dignified, and they 

 remain mated for life. Besides grass- 

 hoppers and worms, they feed largely 

 upon animal matter such as lizards, 

 shell fish, frogs, eggs and young of 

 birds, and carrion. They nest on 

 ledges of high inaccessible cliffs or 

 the tops of tall trees, making large 

 nests of sticks lined with smaller ones 

 and hair or wool; the eggs are laid in 

 April or May, number from four to 

 seven, and are light greenish in color* 

 Size 1.95 x 1.25.

486a. Northern Raven. Corvus corax principalis. 



Range. Eastern North America chiefly north of the United States and north- 

 west to Alaska; south on some of the higher ranges to Georgia. 



This variety is like the last but is larger. They are not nearly as abundant as 

 the western form and are very rare within the United States. A few pairs still 

 breed on some of the rocky islands off the coast of Maine; more off New Bruns- 

 wick and Newfoundland, and they are quite common on the cliffs of Labrador 

 and Alaska. Their nesting habits and eggs are like those of the last.
