WRYNECK (Ger. Wendehals, Dutch draaihalzen, Fr. torcol) , a See also:bird so called from its way of writhing its See also:head and See also:neck, especially when captured on its See also:nest in a hollow See also:tree. The See also:lynx' torquilla is a See also:regular summer visitant to most parts of See also:Europe, generally arriving a few days before the See also:cuckoo, and is known in See also:England as " cuckoo's See also:leader " and " cuckoo's See also:mate," but occasionally is called " snake-bird," not only from the undulatory motions just mentioned, but from the violent hissing with which it seeks to repel an intruder from its hole? The unmistakable See also:note of the wryneck is merely a repetition of what may be syllabled que, que, gue, many times in See also:succession, rapidly uttered at first, but gradually slowing and in a continually falling See also:key. This is only heard during a few See also:weeks, and for the See also:rest of the bird's stay in Europe it seems to be See also:mute. It feeds almost exclusively on See also:insects, especially on ants. It is larger than a See also:sparrow, but its plumage is not easily described, being beautifully variegated with See also:black, See also:brown, See also:buff and See also:grey—the last produced by See also:minute specks of blackish-brown on a See also:light ground—the darker markings disposed in patches, vermiculated bars, freckles, streaks or arrowheads—and the whole blended most harmoniously, so as to recall the coloration of a See also:goatsucker (g.v.) or of a See also:woodcock (q.v.). The wryneck commonly See also:lays its translucent See also:white eggs on the See also:bare See also:wood of a hole in a tree, and it is one of the few See also:wild birds that can be induced to go on laying by abstracting its eggs See also:day after day, and thus upwards of See also:forty have been taken from a single hole—hut the proper See also:complement is from six to ten. As regards See also:Britain, the bird is most See also:common in the S.E., its See also:numbers decreasing rapidly towards the W. and N., so that in See also:Cornwall and See also:Wales and beyond See also:Cheshire and See also:Yorkshire its occurrence is but rare, while it appears only by See also:accident in See also:Scotland and See also:Ireland. Some writers have been inclined to recognize five other See also:species of the genus lynx; but the so-called I, japonica is specifically in-distinguishable from I. torquilla; while that designated, through a See also:mistake in the locality assigned to it, I. indica, has been found to be identical with the I. See also:pectoralis of S. See also:Africa. Near to this is I. pulchricoll is, discovered by Emin See also:Pasha in the E. of the See also:Bar-el-Djebel (This, 1884, p.

28, pl. iii.). Another distinct See also:

African species is the I. aequatorialis, originally described from See also:Abyssinia. The wrynecks (see See also:WOODPECKER) See also:form a subfamily Iynginae of the Picidae, from the more normal See also:groups of which they differ but little in See also:internal structure, but much in coloration and in having the tail-quills flexible, or at least not stiffened to serve as props as in the climbing Picinae. (A. N.) WRY-NECK (See also:Lat. Torticollis), a congenital or acquired deformity, characterized by the affected See also:side of the head being See also:drawn downwards towards the See also:shoulder together with deviation of the See also:face towards the See also:sound side. There are various forms. (1) The congenital, due to a See also:lesion of the sterno-mastoid muscle, either the result of a malposition in utero or due to the rupture of the muscle in the delivery of the aftercoming head in the See also:birth of the See also:breech presentation. (2) The rheumatic, due to exposure to a See also:draught or See also:cold. This is commonly known as " stiff-neck." (3) The See also:nervous or spasmodic, the result of (a) See also:direct irritation of the See also:spinal See also:accessory See also:nerve or its roots, or (b) the result of cerebral irritation. In this form there is generally a See also:family See also:history of nervous diseases, notably See also:epilepsy. This spasm is one of a See also:group of nervous spasms known as " tics," a variety of See also:habit spasm.

The See also:

character of the movements varies with the muscles involved, the most usual muscle being the sternomastoid. The spasm ceases during See also:sleep. Many cases are also due to See also:hysteria and some to spinal See also:caries. When wry-neck is congenital, See also:massage and manipulation may be tried and some form of apparatus. Failing this, See also:division of the muscle surgically ' Frequently misspelt, as by See also:Linnaeus in his later years, Yunx. ' The peculiarity was known to See also:Aristotle, and possibly led to the cruel use of the bird as a love-See also:charm, to which several classical writers refer, as See also:Pindar (Pyth. iv. 214; Nem. iv. 35), See also:Theocritus (iv. 17. 30) and See also:Xenophon (Memorabilia, iii. tr. 17, 18). In one See also:part at least of See also:China a name, Shay See also:ling, signifying " Snake's neck," is given to it (See also:Ibis, 1875, p.

125).may be practised. In the spasmodic forms, See also:

anti-neurotic treatment is recommended, the use of the bromides, valerianates and See also:belladonna, and hydrobromide of hyoscine injected into the muscles has been found of value. T. Grainger See also:Stewart re-commends in persistent See also:tic the trial of continuous and regular movements in the affected group of muscles with a view to replacing the abnormal movements by normal ones. In severe cases it may be necessary to cut down on and stretch or See also:excise the spinal accessory nerve. In rheumatic torticollis the spasm is usually overcome by the application of hot compresses and appropriate anti-rheumatic treatment.
