218 BIRDS OF NORFOLK. 



" They come witli a very rapid fliglit, and pitch into the 

 yew-trees like sparrows into the ivy." Once there it was 

 ahnost impossible to catch sight of them, as they kept 

 amongst the thickest foliage, and it was only by con- 

 ceahng himself that he obtained a chance shot, as they 

 rarely exposed themselves on an open branch, and on

This well-known and handsome species is still, I am 

 happy to say, a common resident in Norfolk, although 

 in some districts its numbers have been sadly thinned, of 

 late years, through the agents of the great " Caterpillars' 



* I am sorry to say that Mr. Doubleday, wlio has for many 

 years studied the habits of these birds in Epping Forest, and 

 was the first to discover their nests in that locality, informs 

 me, in a recent letter, that they are now comparatively rare. " A 

 large portion of the forest (he writes), where this species used to
