hurry from a spot suddenly become so dangerous to their elegant toilettes and rich mantles, are by no means sparing in their invectives against a torment that compels them to forego all the delights of a summer evening's walk with their cavaliers, whose complaints against the authors of the mischief are at any rate equal to their own. For this reason, the _pajaro palmero_, as it is called, is pursued with great eagerness, and every attempt made to drive it from the locality. Frequently in the twilight boys are sent up into the trees with lanterns to catch the birds whilst blinded by the sudden light, and numbers are thus brought to expiate their crimes in the frying-pan, for their flesh is much esteemed. But little, however, can really be done to dislodge them during the summer; it is only in autumn, when the leaves have fallen, and the Alameda possesses no more attraction for their enemies than it does for them, that they condescend to seek a home elsewhere. The same author tells us that he has frequently seen these birds caged in the Canary Isles, but though quite tame, they did not appear to thrive, owing, he imagines, to a lack of insect nourishment. [Illustration: THE TREE SPARROW (_Passer montanus_), AND THE HOUSE SPARROW (_Passer domesticus_).] THE FIELD OR TREE SPARROW. The FIELD or TREE SPARROW (_Passer montanus_) is met with in the middle and northern parts of Europe. It is a small bird, of five and a half inches long and seven and three-quarter inches across the wings, much resembling the Common Sparrow in colour, but easily distinguishable from it. The upper part of the head and neck are reddish brown, the mantle rusty grey, and the bridles, throat, and a spot upon the cheeks black, the remainder of the head being white. The lower part of the body is light grey, the beak black, the feet a reddish horn colour. The sexes closely resemble each other, and the young are scarcely distinguishable from the parent birds.
