INSECTIVOROUS BIRDS. Insectivores. 



CHAPTER I. 



On the general characteristics of Insectivorous 

 Birds. 



THE birds of this order are not so highly 

 celebrated for docility as those of the 

 granivorous or omnivorous tribes, per- 

 haps because but few attempts have been 

 made on their education. Yet we have 

 no doubt they are equally as susceptible 

 of that process as the others, though un- 

 doubtedly it would prove a more difficult 

 task, owing to the natural wildness of the 

 order, and the difficulty and in many 

 instances impossibility of breeding them 

 in confinement.
