Nothing can exceed the dexterity with which they extricate the seeds
from the cones with their bill, the point of the upper mandible of which
they employ as a hook, placing it at the base of the seed, and drawing it
up with a sudden jerk of the head. They frequently stand on one foot
only, and employ the other in conveying the food to their bill, in the
manner of parrots. They are fond of all saline matter.
The flight of this species is undulating, firm, tolerably swift, and ca- pable of being protracted over a large space. While travelling they pass in the air in straggling flocks, and keep up a constant noise, each indivi- dual now and then emitting a clear note or call. They move with ease on the ground, alight sidewise on the walls of houses and on trees, on the twigs of which they climb with the aid of their bill. When caged they soon become tame, and are fed without any difficulty.
I have presented you with a flock of these Crossbills, composed of in- dividuals of different ages, engaged in their usual occupations, on a branch of their favourite tree, the hemlock pine.
Much has been said and repeated respecting the colours of this species as connected with the differences of sex and age. Accustomed as I am to judge of every thing relating to ornithology on the spot where I can procure specimens, and examine them with all necessary care, I have not failed to employ this method in the present case, and I now give it as my opinion that, although learned naturalists may contradict what I am about to state, it will eventually be acknowledged to be correct. I have shot as many specimens of this Crossbill as I could desire, and on opening perhaps more than sixty, which I should suppose enough to know their sexes, in early spring, summer, autumn and winter, I found the young of the year in July invariably similar to the females which had evidently laid eggs that season, excepting that they were smaller, and had their tints duller. The males, which had either been paired or not that season, but which, however, were older than the first (a fact easily ascertained by the inspection of their stronger bills, legs and claws, and their stronger, harder and tougher flesh), shewed a considerable quantity of red mixed with yellow on the rump, head and breast. Others having equal appearances of age were of a dull olive-yellow, and proved to be females. In such specimens as had the bill very much worn on its edges, and the legs and feet diseased from the adhesion of the resinous matter of the fir trees, on which they spend most of their time, and roost on them at night, were of a bright brick-red in certain lights, changing alternately to carmine or
