 the shell tints; browns and grays the markings, 

 which take the form of round spots, blotches, streaks,

 throughout September these Gulls and their young 

 leave the islands and work their way southwards, 

 scattering far and wide over the seas, following the 

 shoals of herrings and sprats and other fish, some of 

 them possibly wandering as far as the Spanish and 

 north-west African coasts. A few Herring Gulls 

 breed here and there among the other species, but

 shires. This is the one species of Gull that breeds 

 on the south coast of Devon, and there its colonies 

 are larger than any we hax'e visited elsewhere in
