Effect of Air-raids and Atr-craft 
Naturalist, 1917, p.140). The Zeppelin raids, 
a feature of the War early in 1915, were nearly 
always heralded in this country by the crow- 
ing of PHEASANTS, and the sensitiveness of 
this species to distant sounds was frequently 
a subject of comment. There seems no 
reason to suppose that PHEASANTS have 
keener powers of hearing than men; it 
appears more probable that these birds are 
alarmed by the sudden quivering of the trees, 
on which they happen to be perched, at the 
time of an explosion (Proc. Roy. Soc. Edin., 
vol. XXXVill. p. 125). It was said that when 
PHEASANTS began to talk the airman got 
ready to fly and the anti-aircraft gunner 
turned out. The crowing of PHEASANTS 
often preceded by fifteen minutes to half an 
hour the approach of hostile aircraft (Daily 
Mail, 1.11.18). During the first Zeppelin 
raid in January 1915, PHEASANTS at Thet- 
ford and Bury St. Edmunds, thirty-five to

Zeppelins flew, shrieked themselves hoarse

battles in the North Sea, PHEASANTS as far
