THE YOUNG NATURALIST. 



the common Reed when the proper time ! 

 arrives. The males are usually darker than 

 those taken at large. — F. Kerry, Harwich. 



Osprey at Huddersfield. — I have just 

 seen a hne male Osprey, recently killed in j 

 this neighbourhood by a game keeper. The 

 bird is in the possesion of Mr. James Varley, 

 and measured rive feet from tip to tip of 

 wings. — S. L. Mosley, Huddersfield. 



Variety of the Rook. — I have lately had 

 submitted for my opinion a pair of young 

 Rooks in a very interesting state of plumage. 

 They are the property of the Rev. G. D. 

 Armitage, and were sent to my father for 

 re-stuffing as " young Hooded Crows, bred in 

 a rookery. 1 ' They are about three parts 

 grown, and are black with the extremity of 

 each feather barred with urey, which gives 

 them a mottled appearance. The ends of 

 the wing and tail feathers are also barred. 

 Mr. John Hancock figures a similar variety 

 in his " Birds of Northumberland and 

 Durham," and calls attention to the fact 

 that this mottled appearance is a charac- 

 teristic of the young of a great many of the 

 Passerine birds. Another instance of a 

 similar variety is mentioned by Yarrell, and | 

 another by Degland and Gerbe in their j 

 " Ornithologie Europeenne." In all these | 

 cases the birds were young birds and the 

 mottled appearance would probably have 

 disappeared if the birds had lived to moult. 

 The one mentioned by Yarrell changed on 

 moulting to an ordinary Rook. — S. L. Mosley.
