I cannot do better than quote from Mr. Hurdis' MS. notes, as follows: 

 " There is no part of the world, perhaps, whose shores are so little fre- 

 quented by Gulls and other sea-birds, as those of the islands of Bermuda. 



"During the violent westerly gales of winter, the Kittiwake is prob- 

 ably seen there oftener than any otber species, being met with from the 

 5th January to the 4th April. About a dozen specimens came under 

 my observation." 



Most of the examples obtained are in immature plumage.
