 curious monotonous notes have gained for them the 

 names of " Tinker or Coppersmith," the little 

 Indian species (Xantholcema hcemacephala) nod- 

 ding its head sideways as it utters its metallic 

 call. Like woodpeckers they bore a hole in 

 a tree, and lay their eggs, which are white, on 

 the chips of wood. Of the Peruvian species 

 of Capita, Stolzmann says that he has found 

 them in small parties on high trees, feeding on 

 fruits in company with toucans, chatterers, and 

 other birds.

 generally sombre, though some African species have white 

 lower backs and the Indian honey-guide (/. xanihonotus) has a yellow back. 

 The name of ' * honey-guide " is derived from the fact that several of the 

 African species will lead men to a bee's nest, sitting on the trees and utter- 

 ing a piping note. If followed, they will fly on 

 in advance a little way, and, as a rule, the bird is 

 rewarded with a little piece of the comb, from 

 which it extracts the grubs. The food of all 

 the species, as far as is known, consists of 

 hymenoptera.

In the woodpeckers the palate is peculiar, 

 and has been termed " saurognathous " by the 

 late Professor W. Kitchen Parker, the vomer being slender,

 arrangement to that noticed in the humming-birds (antea, p. 347). The 

 tongue is long and worm-like, and is capable of being protruded to an enormous 

 length by means of the hyoid bones, the cornua of which extend backwards
