The little nut-brown wren--nut-like, too, in his smallness and round, compact figure--with cocked-up tail and jerky motions and gesticulations, and flight as of a fairy partridge with rapidly-beating, short wings, that produce a whirring noise if you are close enough to hear it, is a familiar creature to almost every person throughout the three kingdoms, and is even more generally diffused than the house-sparrow. Something of the feeling which we have for the swallow, the house-martin, and the robin redbreast, falls to the share of the small wren. He is one of the few general favourites, although, perhaps, not so great a favourite as the others just named. The reason of this is, doubtless, because he is less domestic, never so familiar with man or tolerant of close observation. The wren is never tame nor unsuspicious; he is less dependent on us than other small birds that attach themselves to human habitations, never a ‘pensioner’ in the same degree as the blue tit, dunnock, blackbird, and sparrow. The minute spiders, chrysalids, earwigs, and wood-lice with other creeping things to be found in obscure holes and corners in wood-piles, ivy-covered walls, and outhouses, are more to his taste than the ‘sweepings of the threshold.’ His small size, modest colouring, and secrecy; his activity, and habit of seeking his food in holes and dark places which are not explored by other insectivorous species, enable him to exist in a great variety of conditions--gardens, orchards, deep woods, open commons, hedgerows, rocky shores, swamps, mountains, and moors; there are, indeed, few places where the small, busy wren is not to be met with. This ability of the wren to find everywhere in nature a neglected corner to occupy would appear to give it a great advantage over other small birds; moreover, it is very prolific, and excepting, perhaps, two species of tits, is more successful than any other small bird in rearing large broods of young. Nevertheless, the wrens do not seem to increase. At the end of summer they are very abundant, and you will, perhaps, be able to count a dozen birds where only one pair appeared in spring; but when spring comes again you will generally find that the population has fallen back to its old numbers. The larger increase in summer indicates a greater mortality during the rest of the year than is suffered by other species. The wren is said to eat fruit occasionally, and even seeds; but it is almost exclusively insectivorous, and probably perishes in large numbers during periods of frost, when larks, pipits, and titmice become seed-eaters. Yet the wren is a hardy little bird, a resident all the year round in the coldest parts of our country, and one of the few songsters which may be heard in all seasons. Even during a frost, if the sun shines, the wren will sing as gaily as in summer. His song is his greatest charm. It is unlike that of any other British melodist--a loud, bright lyric,
