Fear in Birds,

peregrine has been observed, Baird says, capturing 
birds, only to kill and drop them. Many of the 
Felidge, we know, evince a similar habit ; only these 
prolong their pleasure by practising a more refined 
and deliberate cruelty. 
The sudden appearance overhead of this hawk 
produces an effect wonderful to witness. I have 
frequently seen all the inhabitants of a marsh 
struck with panic, acting as if demented, and sud-

such occasions I have looked up confident of seeing

drop down as if shot into the reeds or water ; ducks 
away from the margin stretch out their necks 
horizontally and drag their bodies, as if wounded, 
into closer cover ; not one bird is found bold

while, at every sudden stoop the falcon makes, 
threatening to dash down on his prey, alow cry of 
terror rises from the birds beneath ; a sound ex- 
pressive of an emotion so contagious that it quickly 
runs like a murmur all over the marsh, as if a 
gust of wind had swept moaning through the 
rushes. As long as the falcon hangs overhead, 
always at a height of about forty yards, threatening 
at intervals to dash down, this murmuring sound, 
made up of many hundreds of individual cries, is 
heard swelling and dying away, and occasionally,

scream of terror.
