408 THE ORE AT SPOTTED WOODPECKER. 



WE now arrive at the true Woodpeckers, several species of which bird are familiar from 

 their frequent occurrence in this country. 



As is well known, the name of Woodpecker is given to these birds from their habit of 

 pecking among the decaying wood of trees in order to feed upon the insects that are found 

 within. They also chip away the wood for the purpose of making the holes or tunnels 

 wherein their eggs are deposited. In order to enable them to perform these duties, the 

 structure of the Woodpecker is very curiously modified. The feet are made extremely 

 powerful, and the claws are strong and sharply hooked, so that the bird can retain a firm 

 hold of the tree to which it is clinging while it works away at the bark or wood with its bill. 

 The tail, too, is furnished with very stiff and pointed feathers, which are pressed against the 

 bark, and form a kind of support on which the bird can rest a large proportion of its weight. 

 The breast-bone is not so prominent as in the generality of flying birds, in order to enable the 

 Woodpecker to press its breast closely to the tree, and the beak is long, strong and sharp. 



These modifications aid the bird in cutting away the wood, but there is yet a provision 

 ueedf ul to render the Woodpecker capable of seizing the little insects on which it feeds, and 



which lurk in small holes and 

 crannies into which the beak 

 of the Woodpecker could not 

 penetrate. This structure is 

 shown by the accompanying 

 sketch of a Woodpecker's 

 head dissected. The tongue- 

 bones or "hyoid" bones are 

 greatly lengthened, and pass

being fastened in the skull 



Just above the right nostril. These long tendinous-looking bones are accompanied by a 

 narrow strip of muscle by which they are moved. 



The tongue is furnished at the tip with a long horny appendage covered with barbs and 

 sharply pointed at the extremity, so that the bird is enabled to project this instrument to a 

 considerable distance from the bill, transfix an insect, and draw it into the mouth. Those 

 insects that are too small to be thus treated are captured by means of a glutinous liquid 

 poured upon the tongue from certain glands within the mouth, and which cause the little 

 insects to adhere to the weapon suddenly projected among them. This whole arrangement is 

 clearly analagous to the tongue of the ant-eater, described in the volume on Mammalia. Some 

 authors deny the transfixion. 



THE GREAT SPOTTED WOODPECKER is also known by the names of Frenchpie and 

 Woodpie. 



Like the other Woodpeckers, it must be sought in the forests and woods rather than in 

 orchards and gardens. Like other shy birds, however, it sooa finds out where it may take 

 up its abode unmolested, and will occasionally make its nest in some cultivated ground, where 

 it has the instinctive assurance of safety, rather than entrust itself to the uncertain security 

 of the forest. 



In the woods frequented by these birds, which are often more plentiful than is generally 

 known, the careful observer may watch their movements without difficulty, by taking a few 

 preliminary precautions. 



The rapid series of strokes on the bark, something like the sound of a watchman's rattle, 

 will indicate the direction in which the bird is working ; and when the intruding observer has 

 drawn near the tree on which he suspects the Woodpecker to have settled, he should quietly 

 sit or lie down, without moving. At first the bird will not be visible, for the Woodpeckers, 

 like the squirrels, have a natural tact for keeping the tree-trunk or branch between themselves 

 and the supposed enemy, and will not show themselves until they think that the danger has 

 . passed away.
