 surge up to you in the middle of the niglit and die away 

 as they pass. I do not think, sot^s Stuart-Bake' , commenting 

 on H'livifi, that it is because the birds are numerous oi 

 familiar tliat we tliink the sound distinct from that ot 

 other birds'" flight. I remember wlien flrst introduced to 

 the Grarganey how I was struck with the pattering swisb 

 of their flight and then noticed how like a wliistle it 

 rose and fell as it approached and vanished. 



Shovellc"-. — The fliglit of the Slioveller is not quite 

 so rapid as that of other Ducks, but the pinions are moved 

 rapidly and very andi])ly at even some distance.

lied-crested Pochard. — Hume notes their very charac- 

 teristic wing-rustle, which, though resembling that of the 

 Pochard, is loader and harsber. Their wings, he explains 

 are short and, rapidly agitated, make a very distinct palpi- 

 tating, rushing sound, by which even a single bird pass- 

 ing anywhere near one in the stillness of the night can 

 generally be recognised. 



The Pochard. — Their wing rustle, nays Hume, is far 

 more characteristic than that of the White eye, and I have 

 seldom failed to recognise them by it, when T have shot 

 them at night, before they came to hand.
