246 WILD-FOWL AND SEA-FOWL OF GREAT BRITAIN 



those black-backed killers. Either they get knocked 

 off by the Gulls' wings, when sitting out on the 

 rock-ledges, and followed down by their oppressor 

 to where they may fall, or else they are killed and 

 eaten at their very nesting- places. Now the young 

 Cobs may chance to come to grief — but not, I think, 

 very often — from the interference of feathered 

 enemies. It seems a fortunate thing for the diving 

 ducks that such rapacious birds as the Gulls are 

 not able to dive. They can only float about, or, 

 as one might say, paddle on the water, light as corks. 

 Thirty-nine years ago, a female Eider was shot 

 on a Surrey moor, having been driven that way by 

 a fierce gale of wind ; and in 1893 ^ saw a Puffin 

 picked up alive in the same district.
