Adult Female. — Similar to the male, but slightly smaller. 



Young Male — Has the same markings as the adult, but the 

 chestnut is much paler and the black is tinged with brown, 

 and the feathers of the upper surface have distinct brown 

 edges, especially on the wing-coverts ; the white bands across 

 the upper mantle and on the lower fore-neck are not so well 

 defined as in the old bird. 



Range in Great Britain. — A very rare visitor, of which eight 

 authenticated occurrences are on record, the first dating back 

 to 1776, when a specimen was procured near London, and 

 is still preserved in the Newcastle Museum. Nearly all the 

 occurrences of the species have taken place on the east coast, 

 but Mr. Howard Saunders mentions two in South Devon, and 

 one in Caithness. 



Range outside the British Islands. — The Red-breasted Goose 

 breeds in the lower valleys of the Ob and the Yenesei Rivers
