The COMMON NUTHATCH (_Sitta cæsia_) is deep grey on the mantle, and reddish yellow on the under side; a black stripe passes across the eyes to the nape; the chin and throat are white, the sides and lower tail-covers reddish brown, and the quills blackish grey, with light borders (those at the exterior are white at the root); the centre tail-feathers are blueish grey, the rest deep black, marked with blueish grey at the tip; those at the exterior are also decorated with white spots. The eye is brown, the beak light grey above and deep grey on its lower portion, and the foot greyish yellow. This species is six inches long, and ten broad; the wing measures three inches and a quarter, and the tail one inch and two-thirds. The female is distinguished from her mate by her inferior size, the comparative paleness of her under side, and the narrowness of the black line across the eyes. The _Sitta Europæa_ is a very similar species, also inhabiting Europe. These birds are met with in all parts of our continent, from Jutland to the most southern latitudes, and are usually to be seen in pairs or small parties. Although they by no means avoid the society of man, they principally frequent woods and forests, but leave these retreats during the autumn, to wander for a time over the surrounding country. Insects, spiders, seeds, and berries constitute the principal food of the Nuthatches, and they also occasionally swallow gravel or small stones, in order to assist digestion. The eggs, from six to nine in number, are laid about May; these are white, marked and spotted with deep red. The female alone broods, and the eggs are hatched within a fortnight. Both parents assist in the labour of instructing and tending the little family, and rear them principally upon caterpillars. The young remain in the nest until fully fledged, and do not begin life on their own account until after the moulting season. THE SYRIAN NUTHATCH. The SYRIAN NUTHATCH (_Sitta Syriaca_) is somewhat larger than the species above described, from which it also differs in its mode of life and habits. The upper parts of the body are greyish blue, and the under side partially of a yellowish shade; the throat, a large portion of the breast, and the centre of the belly are white; the tail is grey, spotted with yellowish brown on the inner web of the exterior feathers. This species, which is somewhat larger than the bird last described, is commonly met with in Greece, and is also found in Syria, and on the lofty mountains between Bosnia and Dalmatia. Everywhere it exclusively frequents rocky heights, ascending and descending the most precipitous declivities with the utmost facility. It never enters forests, but occasionally seeks shelter in detached clumps of trees. Insects, seeds, and berries afford it the means of existence, and when in quest of these it displays activity and cleverness fully equalling its congeners.
