BLACK-THROATED DIVER. 329 



country, the Black-tliroated Divev is the most rare, occurring 

 but seldom on the southern shores. Young birds have been 

 taken in winter in Corn Avail and Devonshire. In the London 

 market young birds are occasionally to be met Avith, and 

 during the Avinter of ] 836, Mr. Bartlett purchased tAvo, one 

 of Avhich Avas an adult bird Avith a line black throat, this 

 specimen Avas obtained in the month of January ; the other 

 Avas a young bird. Mr. S. Mummery, of Margate, has just 

 sent me notice that a beautiful specimen Avas captured on 

 the 2nd of June last, 1842, in SandAvich Haven, and this 

 being a very fine male bird has been preserved, and deposited 

 in the museum at Margate. I learn from the Rev. Richard 

 Lubbock that in the year 1832, a fine pair Avere killed on 

 one of the broads of Norfolk, Avhich birds are now in the 

 collection of Mr. Penrice ; but that in Norfolk most of 

 the examples of this species have been obtained in Avinter, 

 and these Avere young birds. On the shores of Durham and 

 Northumberland, Mr. Selby considers the Black-throated 

 Diver a rare Avinter visitant. Li 1830 a fine mature speci- 

 men Avas killed at the mouth of the TAveed, and several young 

 birds on different parts of the coast, and upon the river 

 Tyne. Mr. Selby having had an opportunity of examining 

 the bird from Avhich Thomas BeAvick engraved the figure of 

 his Lesser Imber, has no doubt that it is the young of the 

 year of this species. 



In its habits the Black-throated Diver closely resembles 

 the Northern Diver, last described ; and Ave learn also from 

 Mr. Selby some of the localities in Scotland in Avhich this 

 species has been found during summer. This gentleman 

 observes, " that it dives Avith the same ease and as perse- 

 veringly as the other species, and can remain long submerged, 

 making very great progress during its submarine flight, as 

 Avas experienced by Sir William Jardine and myself, Avhen 

 in chase of this bird in a light and handy boat upon Loch
