one approaches the lake, instantly leave their nests and 

 take to the water. To procure these birds two or three 

 persons should go together, never less than two ; one 

 should secrete himself close to the water, and the other 

 move round to the opposite side, and, letting himself be 

 seen, may, by great cauti<$n, drive the birds towards the 

 person in ambush. I have practised this method repeatedly 

 with success. It requires more patience and caution in 

 shooting these birds than any others I know of, excepting 

 the Northern Diver ; for in general they select such a place 

 for the site of incubation, as from its natural situation will 

 admit of their perceiving any one that approaches ; and 

 very often, after creeping a great distance on your hands 

 and knees towards a lake, believing yourself unobserved, 

 on arriving there you have the mortification to find the 

 object of your search is on the side exactly opposite to 

 you." Mr. Hewitson, when on the w r est coast of Norway, 

 saw this species often, upon almost every piece of water, 

 and frequently heard their loud singular scream in an 

 evening at a great distance. My friend, Richard Dann, 

 Esq., sent me the following note : " This Diver is far more 

 common here than the Black-throated. On the west coast 

 of Norway it is very abundant from the Naze to the North 

 Cape. In the Lapland Alps, in the Dofre Field, and in 

 the interior of Sweden, it is equally numerous. In August, 

 1838, I saw on the great Tornea Lake, the source of the 

 Tornea River, thirty in a flock, and all old birds. Although 

 so common, it is rarely one sees the young before they are 

 able to fly ; their habits and mode of feeding their young 

 are similar to those of the Black-throated Diver. Their 

 cries are very mournful and melancholy. During the 

 breeding-season, while on the wing, they utter frequently 

 a sound like the word kakera, kakera, by which name they 

 are called in many parts of Scandinavia. The red neck
