The habitat of the Harlequin Woodpecker extends over the whole of Europe and Central Asia, and it is, we believe, occasionally seen in North-western Africa. Like its congeners, it does not migrate, but only quits its native woodlands to wander over the face of the country during the spring and autumn. At other seasons it keeps strictly within the limits of a certain spot selected as a home, and which invariably contains a large hollow tree suitable as a sleeping-place. "In England," says Mr. Gould, "this small Woodpecker is far more abundant than is generally supposed. We have seldom sought for it in vain wherever large trees, particularly elms, grow in sufficient numbers to invite its abode. Near London it is very common, and may be seen by an attentive observer in many of the parks in the neighbourhood. The Lesser Spotted Woodpecker appears to perform a certain daily round, traversing a given extent of district, and returning to the same spot whence it began its route. In its actions it is very lively and alert. Unlike the Large Woodpecker, it frequents the smaller and more elevated branches, which it traverses with the utmost ease and celerity. Should it perceive itself noticed it becomes shy, and retires behind the branches; if, however, closely engaged in searching for food it sometimes is so absorbed as to allow itself to be closely approached without suspending its operations. When spring commences it becomes clamorous and noisy, its call being an oft-repeated note, so closely resembling that of the Wry-neck as to be scarcely distinguishable from it. At other times of the year it is mute, and its presence is only betrayed by the reiterated tap which it makes against the bark of the tree." Naumann tells us that as this bird retires to rest later than many of the other feathered inhabitants of its favourite groves or orchards, many and fierce battles ensue before it can obtain possession of the particular hole it desires, as Titmice or Sparrows also prefer a warm, snug nook, and are by no means disposed to resign quietly in favour of the would-be intruder. In these encounters, however, might usually overcomes right, and a series of very pointed arguments, in the shape of repeated taps and pecks from the enemy's strong beak, eventually compel the weaker bird to seek a night's lodging elsewhere.
