26 THE LIVING ANIMALS OF THE WORLD 



The group has a wide geographical range, occurring in Europe, Africa, Madagascar, South 

 Asia, the Indian Archipelago, and Australia. 



THE HOATZIN 



This bird is one of the puzzles of the ornithologist. Its pedigree is still a mystery, 

 but it is generally believed to have some relation to the d. inn birds. Its whole life 

 is passed in trees overhanging water, and its flight restricted to short journeys from tree 

 to tree. In South America, its home, it is known by a variety of names, one of which means 

 STINKING-PHEASANT. This is in allusion to the peculiar odour of its flesh, which smells. 

 according to some, like musk, and to others like raw hides. Another remarkable feature of 

 this bird is the fact that it has turned its crop into a sort of gizzard, whilst the true gizzard, 

 having been relieved of its functions, has diminished to the size of a hazel-nut. The unusual 

 purpose to which the crop has been put has brought about considerable modification in the 



form of the breast-bone, which is quite 

 different to that of any other bird. 



The young of these birds are quite .is 

 remarkable as the parents, for almost as soon 

 as they are hatched they crawl out of the 

 nest, along the boughs of the tree in which 

 it rests, to meet the parents coming with 

 food. In these crawling excursions they are 

 aided by the wings, which for a time serve 

 as fore feet. The thumb and first finder 

 armed with strong claws, with which a firm 

 hold is gained on the bark of the tree. 

 To render these claws effective so long as 

 they are necessary, the quill-feathers of tin- 

 tip of the wing have their development 

 checked till the others have grown long 

 enough to serve the purposes of flight.

compressed, enabling them to pass readily 



through the narrow interspaces of dense aquatic foliage. Tin- Kails appear to be related on 

 the one hand to the Game-birds, and on the other to the (.'runes. In si/c they vary from 

 a bird as large as a fowl to one as small as a lark. 



One of the commonest of the Rails is the C< iKN-CKAKK, more commonly, perhaps. 

 known as the LAND-KAIL. Its curious grating cry is one of the commonest sounds which the 

 summer brings with it, and one possessing a charm of its own. Hut rarely seen, it builds 

 its nest in hay-fields, and, when the grass i-, being cut, sits so closely on its treasures that it 

 is sometimes beheaded by the swinging scythe. In the autumn it falls not infrequently to 

 the sportsmen when partridge-shooting. The corn-crake leaves in the winter for the in.. re 

 congenial climate of Africa, a feat th.it seems wonderful when its feeble powers of flight are 

 considered. Its near relative the \Vvil.K-kAll. is rather a handsome bird, but of shy and 

 retiring habr
