The Living Animals of the World 



The group has a ^\-ide geographical range, occurring in Europe, Africa, JMadagascar, South 

 Asia, the Inchan Archipelago, and Australia. 



The Hoatzin. 



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

 but it is generally believed to have some relation to the Game-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 

 SxiXKiXG-rHEASANT. 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 as 

 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 finger are 

 armed with strong claws, with wdiich a firm 

 hold is gained on the bark of the tree. 

 To render these claws efl'ecti\'e so long as 

 they are necessary, the quill-feathers of the 

 tip of the wing have their development 

 checked till the others 

 enough to serve the purposes of flight.

HOATZIX. 

 This is a native of the Amazons Valley, and lives entirely in the trees. 



The Eails. 



The Rails are all water-loving birds, 



dwelling in swauq)s or on the borders of 



lakes and streams. Although all swim 



easily, none have weblied feet. The flight 



is weak ; several species, indeed, have lost 



this power altogether. The body is much 



compressed, enabling them to pass readily 



through the narrow interspaces of dense aquatic foliage. The Eails appear to be related on 



the one hand to the Game-birds, and on the other to the Cranes. In size they vary from ' 



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



One of the commonest of the Eails is the Corn-crake, more commonly, perhaps, 

 known as the Land-rail. Its curious grating cry is one of the commonest sounds which the 

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

 its nest in hay-fields, and, when the grass is 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 more 

 congenial climate of Afi-ica, a feat that seems wonderful when its feeble lowers of flight are 

 considered. Its near relative the Water-rail is rather a handsome bird, but of shy and 

 retiring habits. 



The Weka-rail, a native of New Zealand, is one of the flightless forms to which we
