FAMILY CERTHIIDÆ
THE TREE CREEPER
CERTHIA FAMILIÁRIS
Upper plumage mottled with yellowish brown, dark brown, and white; a pale streak over the eyes; throat and breast buff-white, becoming dusky towards the tail; wings brown tipped with white and barred with white brown, and dull yellow; tail-feathers reddish brown, stiff and pointed. Length five inches, breadth seven inches. Eggs white, with small yellowish red spots.
The Tree Creeper, though a common bird, is less familiarly known than many others of much rarer occurrence, yet, if once observed, can be confounded with no other. In size it ranks with the Tits, Willow Wren, etc., but is less likely to attract notice than any of these, as it never alights on the ground, nor perches on the small twig of a tree. Its note, too, is weak, simple, and unpretending, amounting to no more than an occasional 'cheep', which it utters from time to time while hunting for food, and while performing its short flights. Any one, however, who wishes to see the bird, and knows what to search for, can scarcely fail of success if he looks well about him during a stroll through almost any wood of full-grown trees. Half-way up the trunk of a rugged elm or oak he will observe a small portion of bark, as it were, in motion; the motion, and not the colour, betrays the presence of a small brown bird, which is working its way by a succession of irregular starts up the trunk. Frequently it stops for a few seconds, and is evidently pecking at some small insect, quite noiselessly however. Its beak is not adapted for hammering; it confines its attention therefore to such insects as live on the surface of the bark. It utters a low 'cheep', and proceeds, not in a straight line up the tree, but turning to the right or left according as it descries a probable lurking-place of its prey: presently it disappears on the other side of the trunk, and again comes in view a few feet higher up. Now it reaches a horizontal branch; along this it proceeds in like manner, being indifferent whether it clings sideways, or hangs with its back downwards. Arrived at the smaller subdivisions of the bough it ceases to hunt; but, without remaining an instant to rest, flies to the base of another bough, or more probably, to another tree, alighting a few feet only from the ground, and at once beginning a new ascent. This mode of life it never varies: from morning to night, in winter and in summer, it is always climbing up the boles of trees, and when it has reached the top, flying to the base of others. On one solitary occasion I observed one retrace its steps for a few inches, and stand for a second or two with its head downwards; but this is a most unusual position, as indeed may be inferred from the structure of its tail, the feathers of which are rigid, and more or less soiled by constant pressure against the bark. It frequently visits orchards and gardens in the country, displaying little fear of man, preferring perhaps to hunt on the far side of a tree when any one is looking on; but not very particular even about this, and certainly never thinking it necessary to decamp because it is being watched. To this indifference to the presence of human beings, it owes its name 'familiaris', and not, as it might be imagined, to any fondness for their society, which, in fact, it neither courts nor shuns. It is a quiet inoffensive creature, congregating with no other birds, and being rarely, except in spring, seen in company with even its own species. It builds its nest of small roots and twigs, scraps of bark and grass, and lines it with wool and feathers. A hole in a pollard willow is a favourite place for a nest; in default of this a hollow in any other tree is selected, or the space between the stump of a tree and a detached portion of bark; and it chooses the straw eaves of some shed. It lays from six to nine eggs, which are exceedingly like those of the smaller Tits.
