BIRDS OF WOODLAND AND HEDGEROW. 165 



on page 167, in the ground hard by for the birds 

 to ahght upon when they brought food for their 

 chicks, I pitched my hiding tent close at hand, and 

 covering it with colt's-foot leaves, left it for a day 

 or two, in order that the redstarts might get 

 thoroughly inured to its intrusive presence before 

 I started my photographic operations. 



It is an interesting problem as to how far 

 wild birds credit each other's fears and alarms 

 without some kind of support being lent by the 

 evidence of their own senses. Experience has
