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 other 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.
