decrease in the number noticeable, and if so, when? Are _Grey_-birds the Grey-backed Crows? What is the difference between "House" and "Common" Sparrow? Does the latter mean the Hedgesparrow, or is one the Tree Sparrow? If there be any doubt, a specimen, or the skin, head, or wings sent through the post would serve to identify the species.

If a specimen were procured and sent by post it might easily be identified; or is it the Ringed Dotterel?).
