APPENDIX. 335 



"Of hawks and owls collectively, it may safely be said that, except in rare in- 

 stances, the loss they occasion by the destruction of poultry is insignificant in com- 

 parison with the benefits derived by the farmer and fruit-grower from their constant 

 vigilance ; for when unmolested the one guards his crop by day and the other by 

 night 



" It is earnestly to be hoped that you will succeed not only in causing the repeal 

 of the ill-advised act which provides a bounty for the killing of hawks and owls, 

 but that you will go farther, and secure the enactment of a law which will impose a 

 fine for the slaughter of these useful birds.

"DR. B. H. WARREN, West Chester, Pa.: 



"DEAR DR. WARREN : I am just in receipt of your letter of the 1st instant, and 

 therefore fear that my reply cannot reach you in time for use at the meeting to-mor- 

 row evening. It affords me much pleasure, however, to comply with your request 

 for my views concerning the food-habits of hawks and owls and their relation to 

 man. 



"Of all the species which you name there are only two which, according to my 

 best judgment, are at all seriously destructive to game or poultry, these beine 

 Cooper's Hawk and the Great-horned Owl. The rest, with the possible exception of 

 the Sharp-shinned Hawk, which certainly is destructive to the smaller birds, my 

 experience leads me to regard as very decidedly beneficial to man, their food con- 

 sisting very largely, if not chiefly, of the smaller rodents, field mice especially. 

 The Red-shouldered and Red-tailed Hawks occasionally pick up a young chicken 

 or rabbit, but I feel quite sure that their service to man far outweighs the injury 

 which they thus do. The little Sparrow Hawk and other smaller species destroy 

 large numbers of grasshoppers, locusts and other large insects. 



"Very truly yours, 



"ROBERT RlDGWAY, 



"Curator, Dept. Birds.'"

 "DR. B. H. WARREN, West Chester, Pa. : 



"DEAR DOCTOR : In reply to your letter of the 3d inst., asking for my opinion in 

 regard to the food, etc., of certain hawks and owls specified, I would state that I have 

 read Mr. Robert Ridgway's answer to a similar request from you and that I agree 

 with him in every particular. The idea of persecuting the majority of hawks and 

 owls systematically is simply preposterous, and any law which has for its object 

 their indiscriminate destruction should be immediately repealed, since most of the 

 birds alluded to are among the very best friends of the farmer. In regard to a few 

 species it is well worth while to suspend judgment until a thorough investigation as 

 to their habits and food in your state can be carried out, for, as you are well aware, 

 a species which in some parts of the country and at some seasons may be injurious, 

 in other regions and under altered circumstances may be chiefly beneficial. 



"I remain, yours sincerely, 



" LEON HARD STEJNEGER, 

 "Assistant Curator, Dept. of Birds, U. S. Nat. Mus."
