176 CLASS AVES. 



The Rook. ( C. Frugilegus. Lin.) Enl. 4-84. 

 Naum. 55. 



Still a little smaller, and with the bill more straight 

 and pointed than the carrion crow. Around the base 

 of the beak is without feathers, except during the 

 nonage of the bird, probably owing to its raking the 

 ground in search of food. These two species live in 

 large flocks, and assemble together to build: they 

 devour as much grain as insects. They are found 

 in all Europe, but they remain in winter only in the 

 warmer countries. 



Hooded Crow. (C. Comix. L.) Enl. 76. Naum. 



54. 



Ashy, with the head, wings, and tail, black; less 

 frugivorous than the other species ; frequents the sea- 

 shore, and lives on shell-fish, &c. Naumann tells us, 

 that it often pairs with the black crow, and produces 

 fertile mules. 



Jackdaw. ( C. Monedula. lu.) Enl. 5'3,S. Naum. 



56. 1. 



Still a fourth smaller than the last, being nearly the 

 size of a pigeon, of a less deep black, which becomes 

 ashy round the neck, and under the belly ; some- 

 times also entirely black. Builds in towers ; lives in 

 flocks ; has the same food and habits as the crows, and 

 often associates with them. Tlie birds of prey have 

 no more vigilant enemy.
