Variations in Wood-Pigeon. — This spring I bought at a poulterer's 

 at Forest Hill, S.B., a variety of the Wood-Pigeon (Columba palumbus) 

 with the primary quills and the tail silver-grey, the latter crossed by

 broad black terminal bar. Some years ago I got a close view at the 

 Zoo of a specimen in which this bar was replaced by a silver-grey 

 one, and one wing showed a patch of this hue. I have also seen in 

 Begent's Park on two occasions a bird with one conspicuous white 

 feather in one wing — a large covert, or one of the innermost secon- 

 daries; and in St. James's Park one with the neck-patch wanting on 

 one side and only about half the normal size on the other. This 

 was adult, but rather small, and short in the bill. — F. Finn.
