PREFACE. 



-which the life-history is quite unknown to science. We 

 should studj r birds, not merely keep them as if they 

 were mere luxuries for the gratification of the senses of 

 sight and sound. 



In conclusion, I can only hope that this work will 

 be useful ; it is the result of many months' steady work, 

 and embodies not only my own experience in the care 

 of more than two hundred species of foreign birds, but 

 that of many other strenuous workers. In order to 

 do justice to it, I have had to refer constantly to nearly 

 every book in my ornithological library, and this alone 

 means the collation of interesting facts which cannot 

 be got hastily together.
