from eight to twenty feet from the ground on a branch or in a high

No. 3. NUTCRACKER. (Nucifraga caryocatactes.) 



A native of the pine-clad regions of Europe and Siberia, and a very 

 irregular autumn- visitor to Great Britain, about twenty occurrences 

 having been recorded. Large flocks are sometimes formed in the 

 autumn, when considerable migrations take place in search of food, 

 and stragglers occasionally reach our shores. The nest, which was 

 placed in the fork of a spruce-fir tree about fifteen feet from the ground, 

 is not roofed over, but half-domed nests are occasionally found. The 

 eggs vary from two to five in number, and are pale bluish-green spotted 



with ash-brown.

No. 4. ROOK. (Trypanocorax frugilegus.) 



A common resident and generally distributed over the wooded and

 same " rookery " year after year. The nests are generally placed on 

 the tops of tall trees in the neighbourhood of houses and constructed of 

 sticks and twigs, lined with rootlets, wool, etc. From four to six eggs 

 are laid, and resemble those of the Hooded and Carrion Crows. The 

 food consists chiefly of insects and their larvae ; but in dry seasons, 

 when these are scarce, the nests of other birds are systematically robbed 

 of their eggs.

 and west of Scotland and in Ireland, where the Hooded Crow takes 

 its place. The two species not infrequently interbreed. The nest, 

 composed of sticks and warmly lined with wool, is generally placed 

 on a tree or ledge of rock commanding a wide outlook. The eggs 

 closely resemble those of the Rook and Hooded Crow, and are lour
