He spends the late summer and early autumn in his tangle-hung home, but in winter he generally selects a snug hollow log, or some cavity in the earth. Here he makes a round nest of fine grass and upon a couch of thistledown he sleeps in peace, now and then waking to partake of the little hoard of nuts which he has gathered, or he may even dare to frolic about upon the snow in the cold winter moonlight, leaving behind him no trace, save the fairy tracery of his tiny footprints. Wee, sleekit, cow'rin', tim'rous beastie, O, what a panic's in thy breastie! Thou need na start awa sae hasty, Wi' bickering brattle! I wad be laith to rin an' chase thee, Wi' murd'ring prattle! ROBERT BURNS. WINTER HOLES The decayed hollows which we have mentioned as so often productive of little owls have their possibilities by no means exhausted by one visit. The disturbed owl may take himself elsewhere, after being so unceremoniously disturbed; but there are roving, tramp-like characters, with dispositions taking them here and there through the winter nights, to whom, at break of day, a hole is ever a sought-for haven. So do not put your hand too recklessly into an owl hole, for a hiss and a sudden nip may show that an opossum has taken up his quarters there. If you must, pull him out by his squirming, naked tail, but do not carry him home, as he makes a poor pet, and between hen-house traps and irate farmers, he has good reason, in this part of the country at least, to be short tempered. Of course the birds'-nests are all deserted now, but do not be too sure of the woodpeckers' holes. The little downy and his larger cousin, the hairy woodpecker, often spend the winter nights snug within deep cavities which they have hollowed out, each bird for itself. I have never known a pair to share one of these shelters. Sometimes, in pulling off the loose bark from a decayed stump, several dry, flattened scales will fall out upon the snow among the debris of wood and dead leaves. Hold them close in the warm palm of your hand for a time and the dried bits will quiver, the sides partly separate, and behold! you have brought back to life a beautiful _Euvanessa_, or mourning-cloak butterfly. Lay it upon the snow and soon the awakened life will ebb away and it will again be stiff, as in death. If you wish, take it home, and you may warm it into activity, feed it upon a drop of syrup and freeze it again at will. Sometimes six or eight of these insects may be found sheltered under the bark of a single stump, or in a hollow beneath a stone. Several species share this habit of hibernating throughout the winter.
