412 THE IVORY-BILLED WOODPECKER. 



This splendid bird is armed with a tremendous beak, long, powerful, sharp, and white as 

 ivory, which can be used equally as an instrument for obtaining its food, or as a weapon for 

 repelling the attacks of its enemies, and, in the latter jjoint of view, is a ti'uly formidable arm, 

 as terrible to its enemies as the bayonet, to which it bears no little resemblance in general 

 sliajie. 



Few birds are more useful than the Ivory-billed Woodpecker, which wages continual war 

 upon the myriad insects which undermine the bark of forest-trees, and saves the forest giants 

 from falling a prey to their diminutive adversaries. In one season several thousand acres of 

 huge pine-trees, from two to three feet in diameter, and many of them measuring one hundred 

 and fifty feet in height, were destroyed by the larvfe of a little insect not bigger than a grain 

 of rice. Besides this creature, there are lai'ge grubs and caterpillars that bore theii' way into 

 the interior of trees, and are the pioneers of the destruction that afterwards follows. 



When the Ivory-billed Woodpecker has been hard at work upon a tree, he leaves ample 

 traces of his progress in the heaps of bark and wood chips which surround the ti'ee, and which 

 look, according to Wilson, as if a dozen axe-men had been working at the trunk. Strips of 

 bark seven or eight inches in length are often struck off by a single blow, and the body of the 

 tree is covered with great excavations that seem more like the work of steel tools than of a 

 bird's beak. Yet these apparent damages are really useful to the tree, as the sound wood is 

 allowed to remain in its place, performing its proper functions, while the decaying substances 

 are scooped out in oixler that the bird may get at the grubs and beetles that make their home 

 therein. 



As in the case of all AVoodpeckers, the beak is also employed in excavating the holes 

 in which the eggs are laid. Tlie following account of the nesting of this bird is given by 

 Audubon : — 



" The Ivory -billed Woodpecker nestles earlier in spring than any other species of its tribe. 

 I have observed it boring a hole for that jaurpose in the beginning of March. The hole is, 

 I believe, always made in tlie trunk of a live tree, generally of an ash or a hagberry, and is at 

 a great height. 



" The birds pay great regard to the particular situation of the tree, and the inclination of 

 its trunk, first because they prefer retirement, and again, because they are anxious to secure 

 the aperture against the access of water during beating rains. To prevent such a calamity, the 

 hole is generally dug immediately under the Junctiire of a large branch with the trunk. It is 

 first bored horizontally for a few inches, then directly downwards, and not in a spiral manner, 

 as some people have imagined. According to circumstances, this cavity is more or less deep, 

 being sometimes not more than ten inches, whilst at other times it reaches nearly three feet 

 downwards into the core of the tree. I have been led to think these differences result from the 

 more or less necessity under whicli the female may be of depositing her eggs, and again have 

 thought that the older the Woodpecker is, the deeper does it make its hole. The average 

 diameter of the different nests which I have examined was about seven inches within, although 

 the entrance, which is perfectly round, is only just large enough to admit the bird. 



"Both birds work most assiduously at this excavation, one waiting outside to encourage 

 the other whilst it is engaged in digging, and when the latter is fatigued, taking its place. 

 I have ajjproached trees whilst these Woodpeckers were thus busily employed in forming 

 their nest, and by resting my head against the bark could easily distinguish every blow given 

 by the bird. I observed that in two instances, when the Wooodpeckers saw me thus at the 

 foot of tlie tree in which they were digging their nest, they abandoned it forever. For 

 the fii'st brood there are genei'allj^ six eggs. Thej^ are deposited in a few chips at the bottom 

 of the whole, and ai'e of a pure white color. The young are seen creeping out of the hole 

 about a fortnight before they venture to fly to any other tree. The second brood makes its 

 appearance about the IStli of August." 



The courage and determination of the Ivory-billed AA'oodpecker is very great, and it will 

 fight with its opi^onent in a most desperate manner. When wounded, it endeavors to reach 

 the nearest tree, and to run up its trunk, and if intercepted will peck as fiercely at the hand 

 of its piarsuer as at the wood and bark, and is able to infiict severe injury with its sharp
