the commonest Hawk in the district, but curiously enough I have never seen 

 the Sparrow-hawk, which seems to be conspicuous by its absence, and 

 although the eggs of the Kestrel are common objects in the cottages, I have 

 never seen an egg of the Sparrow-hawk in the place. The Merlin breeds on 

 the moors not uncommonly, and has a bad name. 



(To be concluded.) 



TO CORRESPONDENTS. 



All Editorial communications and Books for Review or MSS., must be sent 

 to H. K. Swann, 10, Harrington Street, London, N.W. To be dealt 

 with in the following issue, communications must be received by the

Subscriptions (one year, 6s. ; half-year, os. 3d.) and Advertisements must be 

 sent to John Bale & Sons, 85-89, Great Titchfield Street, London, W. 



G. E — W., Warrington. — (1) The specific distinctions are so slight that 

 they can only be appreciated by a comparison of individuals cf each species. 

 Corvus americanus seems to differ from C. corone more in note and habits 

 than otherwise. We have found the note to be very different, being sharper 

 and more querulous, while the bird seems to approach somewhat to our Rook 

 in being distinctly gregarious, often even nesting in company. (2) The 

 case of the Sparrow-hawk roosting on your friend's house for so long a 

 period is to be in part explained by the fact that it had not found a mate ; 

 it was probably a young bird just sent forth by its parents when first noticed. 



A. E. 8., Surbiton Hill. — We have a large number of photographs of the 

 commoner British birds' nests, and are therefore unable to use those sent. 

 If you make any of very rare or curious nests or birds we shall be pleased to 

 see them. We do not pay for photographs by amateurs, but are always 

 pleased to acknowledge the photographer. 



We stated last month that we should be glad to receive names of a few 

 oblogists who desired to form a circle for starting an "exchange basket," 

 but we find that an insufficient number of names have been sent in. If any 

 more subscribers wish to send in their names, will they kindly do so at once. 

 Dr. Gunning, of Montrose, N.B., has kindly undertaken the formation of 

 this exchange club.
