FARNE ISLANDS AND THEIR BIRDS 179 



wounded bird such as this can do an enormous 



amount of harm. It is impossible to chase it if 



seen, for if anyone was to commence running or 



walking at random 



over the island 



they would break 



large quantities 



of eggs. When 



on Fame Island 



we often saw 



clouds of terns 



rise from different 



spots at different 



times on the 



Wideopens, and 



although we could 



not see the gull, 



owing to the tall 



campion, yet we 



judged that these 



alarms signified 



that the robber 



was making a 



raid. Eider ducks 



breed on both 



islands ; the majority of these seemed to prefer 



nesting in the open, but a few nests were found 



amongst sea-campion.
