the Petchora its breeding-range extends to the Taimyr 

 Peninsula and possibly to east Siberia. In winter it is 

 found over the greater part of Europe and western Asia, 

 and is common in China. Eastwards its place is taken by 

 the larger, thick-billed form, A. f. serrirostris. 



A form with the bill mostly yellow has been separated as 

 A. arvensis and occurs in the British Islands, but its claims 

 to specific distinction are extremely doubtful.

Distribution in the British Islands. A Winter Visitor. 

 Generally scarce on the east coast of Great Britain, except 

 near the Moray Firth, but on the west and south often 

 numerous, though local in its distribution. It is rather 

 plentiful in the Shetlands and Orkneys, much less so in the 

 Outer Hebrides, but common in Islay. In Ireland it is 

 abundant and much the commonest species of Grey Goose. 



General Distribution. The breeding-range of the White- 

 fronted Goose includes Greenland, Iceland, the most 

 northerly tundra of Arctic Europe, Kolguev, and Novaysi 

 Zemlya, the extreme north of Siberia, and the islands along 

 the shores of the Arctic Ocean. In winter it is met with 

 throughout Europe, south to the Mediterranean basin, 

 Egypt, 'the Black and Caspian seas, northern India, China, 

 Korea, and Japan. In Arctic America, A. a. gambeli, a form 

 with a slightly larger bill, is met with, ranging south in 

 winter to Mexico and Cuba. It seems doubtful if the 

 American bird is really separable from A. albifrons.
