The Hooded Crow, so called, most probably, on account of the distinct black covering of the head and neck, is not a very common bird in England generally, although it may often be found in certain localities, and at certain seasons, for it is partly migratory, frequenting the southern parts of the island only in winter, usually from October to April. In the north of Scotland, and the Hebrides and other islands, they are always to be found, and in great numbers. In its habits the Hooded Crow resembles the common kind, except that it is more of a coast bird, seldom being found far from the sea-shore, or the banks of estuaries, or tidal rivers. Its nest is generally placed on tall trees, or the clefts and chasms of rocks and hill sides. Mr. Morris describes it as composed of sticks, roots, stalks, or heather, lined with wool and hair. The eggs are from four to six in number, of a green tint, mottled over with greenish brown; some have been found of a yellowish tinge, or with dashes and streaks of yellow, others of a uniform dull dark green, with but few spots or variations of any kind. It is the opinion of some naturalists, that the Hooded and Carrion Crows are but varieties of one species, and certain it is that they do sometimes breed together, but there appears to be sufficient distinctive marks and characteristics to warrant the specific difference assumed for them by most of the leading ornithologists. Frequenting as it does the sea-shore, the Hooded Crow, which may be known by its distinctly marked plumage of dull grey, extending all over the back, breast, and belly, feeds much on shell-fish, which it bears up to a great height, and then lets fall on a large stone or piece of rock, so as to break the shell. We have here an instance of something very like reasoning power, in what we must call an unreasoning creature, nor are such instances at all unfrequent in natural history. ROOK. BARE-FACED CROW. YDFRUN, OF THE ANCIENT BRITISH. FIGURE 7. Naturalists term this bird _Corvus frugilegus_. With the meaning of the first, or generic name, our readers are already well acquainted; the specific name comes from the Latin _fruges_--fruits, and _lego_--to collect or gather, and from this we learn that it is a _frugiverous_ or fruit-eating bird; it is not, however, altogether so, for it feeds much on insects, worms, slugs, and such small animals, in search of which it digs or delves with its large and strong beak, all around the base of which is bare of feathers, hence the name Bare-faced Crow, by which the bird is known in some localities. It is a matter of dispute whether or not this bareness is caused by the constant use of the bill as a digging instrument; we are inclined to think not, for several reasons, which need not here be stated; but, that the bare whitish skin which surrounds the beak, and which offers such a strong contrast to the rest of the purplish black plumage, is a natural distinction.
