Is this produced by a difference in the cleanly dispositions of these two birds, or is it a constitutional difference? MODE OF TAKING.--When, in winter, any spot has been remarked which the larks prefer, a place must be cleared from snow, some oats and poppy-seed be thrown upon it for a bait, and limed twigs, nets, or even a simple gauze, be conveniently arranged, and soon plenty will be caught. ATTRACTIVE QUALITIES.--The song of the crested lark is, in my opinion, very inferior to that of the sky-lark; it seems composed of the warbling of that and of the linnet; this bird sings also in the night. Its time of singing lasts from February to August, but longer in those birds which have been tamed from the nest. It has not the tottering gait of the sky-lark, but runs nimbly, and moves its crest in the most expressive way. It is rather quarrelsome, and has the peculiarity that when it fights it continues to sing. THE WOOD-LARK. Alauda arborea, LINNÆUS; Le Cujelier, ou L'Alouette des Bois, ou La Loulou, BUFFON; Die Waldlerche, BECHSTEIN. This charming species is one-third smaller than the field-lark, and resembles it much in form and gait. The beak is black above, brown below, tending to carnation at the tip. The shanks, three quarters of an inch high, are of a brownish flesh-colour. The top of the head is reddish brown, with four dark brown lines; its long feathers render the head large, and they may be raised at pleasure into a crest, which from eye to eye is surrounded by a whitish ash-coloured line. The tail is very short. The female, more beautiful, is of a paler ground, with darker ornaments; her breast more spotted; the crest on her head more prominent, and the line round the cheeks more distinct. It is a well attested observation made on all our indigenous species, that the individuals with the most spots on a lighter ground, and of a clearer white, are certainly females. HABITATION.--When wild these birds inhabit the temperate regions of Europe, in summer the woods of the plain, near fields and meadows, and in the woods of the hills they alternate between heaths and pasture lands. After breeding time they assemble in small flocks of ten or twelve. They are thus found in the stubble, at their departure in October, and their return in March. In the house I prefer letting them run about, because my experience shows that they sing better in this way than when caged. They must be well supplied with river sand, as well to roll and dust themselves as to pick out grains necessary for their digestion. FOOD.--When wild, in summer, the food consists of insects; in autumn, of rape, millet, seed, and oats; in spring, before they can find insects and worms, they are satisfied with the young buds of herbs, water-cresses, and, on an emergency, with the buds of the filbert.
