THE LITTLE GREBE, ETC. 177 



Professor C. S. Sundervall stated that the P. arcticus 

 and the P. cornutus were identical, but in different 

 stages of plumage. Kjaerbolling considers them to be 

 distinct. 



The eared grebe (P. auritus) is scarce everywhere 

 in this country, but is occasionally seen in all likely 

 localities. It is easily distinguished from other species 

 by a tuft of orange-yellow feathers on the cheeks, 

 which passes over the auriculars, and looks as if it had 

 been brushed off the face of the bird by a human hand. 

 Nilsson calls it the svart-halsad dopping, or black- 

 necked dipper. It makes its nest in the reed beds 

 of rivers and lakes. 



The little grebe (P. minor) is only found in the 

 south of Norway. It has been shot at Horten, a town 

 on the Christiania-fjord, as early as the beginning of 

 March. It is called in Norway the lille dyMer, or little 

 diver. 



We come now to a class of birds which are strictly 

 maritime in their habits, and breed in colonies on the 

 north-west coast of Norway. Many of these birds, 

 however, venture inland during the winter months, and 

 thousands of auks and guillemots are seen on the 

 Christiania-fjord in autumn. 



The common guillemot (Uricu troile) is found by 

 thousands during the breeding-season on the west and 

 north-west coast of Finmark. It is called in Sweden 

 the sill dopping, or herring dipper, on account of its 

 partiality for young herrings, which abound on the 

 east coast of Sweden and on the west coast of 

 Norway. It often lays its single egg on the bare 

 rock. The colour of the egg varies considerably, 

 sometimes being whitish-green, at others of a very
