Box A is suitable for the great tit, blue tit, marsh-tit, coal-tit, 

 crested tit, nuthatch, tree-creeper, wryneck, pied fly-catcher, redstart, 

 or lesser spotted woodpecker. In accordance with the wish of many 

 who are interested in the matter, and suffer greatly from the plague 

 of sparrows, a box called Al has lately been made with a narrower 

 opening 1 1-16 inch. It is designed for blue tits, marsh- tits, coal-

tits, and crested tits ; sparrows cannot enter it, but 'neither can 

 other birds, except the small tits, not even the great tit. 



Box B is for starlings, greater spotted woodpeckers, wrynecks, 

 nuthatches, pied fly-catchers, redstarts, 

 great tits. The last five species settle in 

 box A as well as in B. The former suffices 

 as a rule. 



Box C is for green woodpeckers ; and 

 Box D for stock-doves,* kestrels, jackdaws, 

 and owls. 



For the sake of completeness we have 

 box E for swifts, with the boring of 

 box B, and a semi-circular opening. (See 

 illustration.) 



The open box F has a diameter of about 

 4J inches, and a depth of about 2J inches. 

 It is made for such birds as redstarts, 

 spotted fly-catchers, and pied wagtails. 



* I should like to awaken interest in pigeon preserves, such as were common 

 in Germany in the seventeenth and eighteenth centuries, when these birds afforded 

 a pleasant addition to the menu. It would be a good plan to hang a number of 

 boxes in close proximity to each other in suitable districts where the stock-dove 

 is already found. The most suitable places, it seems to me, would be preserves 

 for game where the necessary protection from interference and poaching is 

 already to be found.
