pink coloTir of the bill and feet is found not to be constant, and 

 Seebohm says, ' It looks very nnicli as if the pink-footed geese bad 

 been long enough in the arctic climate of Spitzbergen to change the 

 colour of their feet, but not long enough to make the new colour 

 permanent, and that when bred in the warmer climate of this 

 country they had a tendency to hark back to their ancestors.' 



White-fronted Goose. 



Anser albifrons. 



White on the forehead and at the base of the lo^ver mandible ; 

 upper parts brownish ash ; breast and belly brownish white broadly 

 barred with black ; bill orange -yellow, with a white nail at the tip ; 

 legs and feet orange. Length, twenty-seven inches. 



The white-fronted goose is the fourth and last on our list of grey 

 geese— four forms of one species, as some hold — and, like the others, 

 it comes to us from the north in winter, but is more common in 

 Ireland than in Great Britain. It is like the bean-goose in size, but

 sound, and the rapidly repeated notes give its cry a laughter-like 

 character ; laughing goose is one of its common names. It breeds 

 farther north than the bean-goose, and its nest is described as a 

 hollow in the groimd lined with dead grass. It lays five to seven 

 creamy white eggs. 



Brent Goose. 



Bernicla brenta. 



Bill, head, throat, and neck black, except a small white patch 

 on each side of the latter; mantle brownish black with rufous- 

 brown edges ; wing-feathers, rump, and tail black ; coverts white ; 

 upper breast black ; lower breast and beUy slate-grey ; legs black. 

 Length, twenty-three inches. 



The brent goose arrives in our islands in the autumn, and 

 remains tlnrough the winter in suitable locaUties in various parts of 

 the coast, from the Orkneys and Shetlands in the north to the
