After having taken the young from the nest they must be put in a cage, and placed at the foot of the tree in which this nest is built, in a place dug for the purpose, and on the cage a tit as a decoy. When left there, the old birds come to feed their young, and are caught in the snare. As soon as they are taken, they must all be brought into the house, where the old and young must be put together in any aviary, or large cage, till the latter can fly; the window may then be opened for them to go out, but hunger will soon bring them back. As soon as they have exercised their wings, the old birds should be placed on the table in the window to call them back. In time, they become so familiar that they will accompany one in a walk, and there is no fear of their flying away. If they are not taken thus, it is necessary to wait for winter and snow to let them go out, and if they profit by the permission, to call them back by some of their species placed in a cage in the window. If you wish to be quite sure of success, you have only to put a board in the window, on which two females with their wings cut, can run about, go out, and return.
The green bird likes to build near canaries, and as these are good nurses, they are given the eggs of the green bird, which, like the goldfinches and siskins, learns to draw up its water and food.
THE PINE GROSBEAK.
Loxia Enuclator, Linnæus; Le Durbec, Buffon; Der Fichtenkernbeisser, Bechstein.
This is one of the largest species of grosbeak that we have, equalling the Bohemian chatterer in size. Its length is eight inches and a half, of which the tail measures three; the beak is short and thick, measuring only six lines; its colour is brown, the iris dark brown; the feet are from twelve to thirteen lines high, and blackish; the head, neck, breast and rump are of a light vermilion, with bluish tints; the feathers on the back and the lesser wing coverts are black, with reddish edges.
The female is generally of a greyish green, with some scattered reddish and yellowish tints, principally on the top of the head. It is not yet well known if this bird has the same changes of colour as the crossbill, since more yellow ones have been found than red. Experience shows that the same things take place in the house as out of doors. They acquire the yellow red, not only after the first moulting, but even before it. This change begins first round the beak, descends afterwards to the back and breast, and at last gradually extends over the whole body, so that what was red before becomes yellow; this yellow is darker than citron; all the red and yellow feathers are ash-colour at the base. The young are brownish, with a slight shade of yellow. During the first year the colour of the males is light red; it is only after this that they become darker vermilion or crimson; these birds are caught in autumn and winter, either in the noose or net, with elder or service berries as a lure.
Observations.—This bird is found in all the northern regions of Europe, Asia, and America, and in Europe rarely passes the fifty-third degree of latitude. It frequents the pine and fir forests, the seeds of which form its food; in winter it quits these places in search of berries; this is what ranks it among the erratic birds. They are so stupid, that in the north they are easily caught with a circle of brass wire fixed to the end of a long pole, to which are fastened some horse-hair rings, which are simply passed over the head of the bird. They are often caught and kept in cages, as they are liked, both on account of the ease with which they are tamed, and of their song, which is very agreeable; they will even sometimes sing in the night, and always preserve their song through the whole year, while the wild only sing in the spring.
