do, as shown by more than one species, especially Lesser 
Black-backed Gulls (Larus fuscus affinis ), bred in this 
country, of which quite an encouraging percentage has been 
recovered. 
Neither is any mention made of Palmen’s ducks marked 
in the far north, which show some wonderful results, two 
Teal, for instance, being recovered in Spain and Italy 
respectively. His Starling records are also intensely 
interesting, showing, as they do, several recoveries in this 
country. In the article three records only are given of 
Swallows marked with ‘British Birds’ rings being recovered 
in South Africa, whereas the number should be five. Again, 
no mention is made of the wonderful record of a Wigeon 
marked with a ‘British Birds’ ring in England and recovered 
in Asia. With regard to the supposed sedentary habits of 
the British Redbreast, I can quote at least two instances of 
such marked birds being recovered abroad. 
Finally, it would be interesting to learn the total number 
of birds marked by the American Bird Banding Association. 
I might conclude by saying that Mr. F. W. Smalley and 
myself once marked 720 birds of one species in the course 
of one day.

Birds of Alderney. 
Sir, —I notice that in Major W. R. Thompson’s in¬ 
teresting paper in the July number of ‘The Ibis’ on the 
Birds of Alderney, he assigns the Goldfinch, Bullfinch, Tree- 
Creeper, Great Tit, Blue Tit, Song-Thrush, Robin, and 
Dipper to the British forms without comment. Referring 
to Mr. Witherby’s ‘Practical Handbook/ I find that all 
these are said to be confined to the British Islands except 
the Song-Thrush and Robin. I do not know whether birds 
of all these species from north-west France have been com¬ 
pared with the British forms, or whether Channel Island 
birds have been compared with either French or British ;
