base of the lower; legs and feet orange; irides hazel; orbits 'carmine ; 

 bare horny skin above and below the eye slate-grey; loose skin at the 

 gape yellow. After the autumn moult the sheath of the basal half of 

 the bill is cast, as are also the warty red skin round the gape and the two 

 appendages above and below the eye. Young in first plumage closely 

 resemble adults in colour, but the throat and sides of the head are more 

 suffused with grey, especially the lores ; the bill is also less than half the 

 depth, somewhat resembling that of the Razorbill in shape, and yellowish- 

 brown in colour ; the legs and feet are much duller in colour. Birds of 

 the year closely resemble adults, except that the bill is intermediate. 

 Young in down are uniform blackish brown.
