captivity. Some planters complain of their propensity to scratch the ground for the purpose of picking up the newly planted corn; but I am of opinion that the scratching has reference exclusively to worms or beetles, their strong legs and feet being well adapted for this purpose; and, generally speaking, they are great favourites, as they commit few depredations on the crops.

This species, as well as the R,obin and some others of this genus, suffer greatly during the autumnal moults, and when in cages at this season, become almost naked of feathers. The young acquire the full beauty of their plumage during the first winter.
