FAUNA AND FLORA. 31 



in describing this bird, says that " they feed entirely upon marine 

 Crustacea," that he never " found fish in their craws," and that " the 

 young are fed by the disgorging parents." My observations do 

 not confirm these remarks. I have often seen them capture small 

 fish about 2 inches in length, and fly away with them in their 

 bills to their young. 



Once while gathering eggs on Avos rock, I found, laid beside 

 each egg that was just on the point of being hatched out, one of 

 these small fish, evidently placed there in readiness for the young 

 chick. 



(13) Fratercula monocerata, horned-bill guillemot. Found 

 about Shikotan and the small islands off" the east coast of Yezo, 

 where it breeds in large numbers. I have not noticed this bird even 

 so far north as Yetorup. 



(15) (?) Podiceps (?), grebes. A few of these birds have been 

 noticed on the lagoons and ponds of the islands, but the species was 

 not ascertained. 



(18) Colymhus ardicus, black-throated diver. 



(19) Colymbus septemtrionalis, red - throated diver. Very 

 common in early spring, when numbers are to be seen making their 

 way northwards along the islands. A few breed on Paramushir 

 and Shumshir. 



(18^) Colymhus adamsi, great white-billed diver. A few 

 seen. 



(20) Cygnus musicus, hooper swan. A few frequent the 

 islands. Noticed on Yetorup in winter. 



(22) Anser sagetum scrrirodris, bean goose. 



(24) „ cdhifrons, white-fronted goose. 



(25) „ minidus, lesser-fronted goose. 



(26) „ cygnoides, Chinese goose. 

 (28) „ liiUchinsi, Hutchins' goose. 

 .(29) „ nigricans, Brent goose. 



All these geese are to be found as visitors either to the northern 

 or southern islands, but they are never seen in large numbers. A 

 lew A. hidchinsi have been noticed breeding on Ushishir and 

 Ekarma. A nest with six eggs and another with seven were found 

 on the 16th of May. Young ones were found on the 20th of June. 



(30) Anas hoscJias, mallard duck. 



(31) „ zonorhyncha, dusky mallard duck.
