up more than two young birds ; sometimes only one. Mr. 

 Proctor saw flocks of Divers when at Iceland, in the mid- 

 dle of summer, but not one of them had a white throat, 

 nor can I find any record of the capture of Divers with a 

 white throat in summer, except very late in that season in 

 Norway, and these were ftvo small and young birds of the 

 year, only two or three months old. The few Divers ob- 

 tained with dark-coloured throats in winter, compared to 

 the number of those taken having white throats, seem to 

 make the former rather the exception than the rule, and I 

 have known a specimen of our common Tern, killed in 

 December, with a black head, thus, perhaps from some 

 morbid cause, carrying the strongest mark of its breeding 

 plumage through the winter.
