The Wood Lark — Alauda Arborea, Linnæus
The Wood Lark is a much rarer bird than the Skylark, and very local in distribution. Rows of trees bordering open fields are the localities chiefly favoured by this species, which, except that it frequently perches, and may often be heard singing from the topmost branch of a tree, much resembles its commoner congener in habits. It feeds almost entirely on the ground, living chiefly on insects. The nest is placed a few yards from the hedge and composed of bents and grass, with a lining of finer materials. The eggs, usually four in number, are of a creamy ground colour, very thickly freckled with reddish brown markings. This species may be most easily distinguished by its song, which is much sweeter and fuller in tone than that of the preceding bird, but lacks the power and exuberance. When rising from the ground to sing, it always does so in a wide spiral curve, differing in that respect also from the Skylark, which rises straight.
The sexes are alike in plumage and resemble the Skylark, but it is a smaller bird and has a short hind toe and is more heavily streaked on the back. Length 6 in.; wing 3·6 in.
