146 THE BIRDS OF MONGOLIA ETC. 



288. Graculus carbo. Badan hohhoy. 



During the vernal migration, late in March, we saw large numbers of 

 these birds on Lake Dalai-nor, where they probably remain to breed, and 

 about the end of April in the Hoang-ho valley, from which they disappear 

 for the summer. At Koko-nor the earliest migrants appeared on the 12th 

 of March, and were very plentiful later on in the month, especially on the 

 Buhain-sol : but towards the end of March their numbers diminished consi- 

 derably, as only a few pairs breed here, on account of the want of high over- 

 hanging rocks. 



At Lake Hanka they arrive early in March, and are very numerous 

 about the middle of that month on the Sungatch. For whole days their loud 

 hoarse voice and the fluttering of their wings are to be heard. After feeding 

 they perch on some overhanging willows ; and often w-hole flocks can be seen 

 at night roosting on dead trees. 



Not being pursued by man, these birds get very tame in Mongolia and 

 the Ussuri country, but are not very easily shot, as they can carry a heavy 

 charge ; and even when mortally wounded they very often escape by diving. 



About the beginning of April almost all these birds leave Hanka for the 

 north ; a few probably remain, but do not breed. On the coasts of the 

 Japanese Sea they have young on the rocky shores, and sometimes even stay 

 there for the winter. 



289. Pelecanus crispus, L. ^ Pelican kudriavey. 



Most likely it was Pelecanus crispus that P^re David discovered. We 

 saw it on the Dalai-nor and in the Hoang-ho valley : in the former place we 

 found only one, on the 29th of March ; and in the latter, two in summer and 

 one in spring. 



We did not come across any Pelicans in any other locality which we 

 visited.
