322 AMERICAN CROW. 



Its gait, while on the ground, is elevated and graceful, its ordinary 

 mode of progression being a sedate walk, although it occasionally hops 

 when under excitement. It not unfrequently alights on the backs of cattle, 

 to pick out the worms lurking in their skin, in the same manner as the 

 Magpie, Fish-Crow, and Cow-bird. Its note or cry may be imitated by 

 the syllables caw, caw, caw, being different from the cry of the European 

 Carrion Crow, and resembling the distant bark of a small dog. 



At Pittsburgh in Pennsylvania I saw a pair of Crows perfectly white, 

 in the possession of Mr Lampdin, the owner of the museum there, who 

 assured me that five which were found in the nest were of the same 

 colour. 



I have placed the pensive oppressed Crow of our country on a beauti- 

 ful branch of the Black Walnut tree, loaded with nuts, on the lower twig 

 of which I have represented the delicate nest of our Common Humming 

 Bird, to fulfil the promise which I made when writing the history of that 

 species for my first volume. 



In conclusion, I would again address our farmers, and tell them that if 

 they persist in kiUing Crows, the best season for doing so is when their 

 corn begins to ripen.
