POCHARD. 337 



North of England, it is found at the Orkney and Shet- 

 land Isles, in Denmark and Sweden ; but neither Mr. 

 Hewitson nor Mr. Dann mention having seen this Iftick 

 either in Norway or Lapland. It goes, perhaps in its mi- 

 gration, more to the eastward, as it is said to be abundant 

 in Russia and the north of Germany. Mr. Blythhas ob- 

 tained it at Calcutta. 



The adult male has the bill black at the point and the 

 base ; the intermediate portion pale blue, forming a broad 

 transverse band ; the irides red ; the head and upper part 

 of the neck all round rich chestnut red ; the neck below 

 deep black; back, scapulars, tertials, and wing-coverts, 

 freckled over with minute grey specks and lines, on a 

 ground of white ; primaries and secondaries nearly uni- 

 form grey ; the primaries ending in dark brown ; the se- 

 condaries narrowly tipped with white ; rump and upper 

 tail-coverts nearly black; tail-feathers uniform greyish- 

 brown ; breast, sides, and belly to the vent, greyish-white ; 

 produced by minute grey marks, on a white ground ; under 

 tail-coverts black ; legs and toes bluish-grey, the interve- 

 ning membranes bluish-black. 



The whole length is nineteen inches and a half. From 

 the point of the wing to the end of the first quill -feather, 

 which is the longest, eight inches and a quarter. 



The adult female has the bill black ; the irides brown ; 

 head, and all the back of the neck, dusky greyish-brown ; 

 back and wings darker grey than that of the males ; quill- 

 feathers like those of the males ; no bright-coloured spe- 

 culum in either sex ; chin and throat pale greyish-brown ; 

 lower part of the neck in front dark brown ; all the under 

 surface of the body uniform dull greyish-white; under 

 tail-coverts dark grey ; legs and feet as in the male. 



Young males at first resemble the females, obtaining 

 some change with the feathers of their first autumn moult ;
