36 EINAR LÖNNBERG, BIRDS. 



Anhinga rufa (Lacép. Daud.). 



Rciiw. I, p. 95. 



Single specimens of this species were seen sometimes at Guaso Nyiri below Chanler 

 Falls but at no other place. The other rivers which we passed were probably too small 

 to suit this bird. At Guaso Nyiri the Anhingas were only seen in single specimens either 

 fly ing över and along the river or resting on some dry branch of a tree. They were not 

 very shy. 



Anatidse. 



Anas undulata Dubois. 



Rchw. I, p. 113. 



When crossing a small river between Kagio and Kutu 24 /i, I flushed three ducks 

 and succeeded in bagging them all after a while. They were strongly stained by the red 

 clayey soil on their lower parts and looked therefore much darker and redder, especially 

 underneath than if the real colours of the plumage had been fully visible. 



The 27 th March I saw and shot a young duckling in down as far as I could see be- 

 longing to this species, although I did not secure the mother bird. I did not see more than 

 two youngs and the mother. It was in a small river in the thick forest on the eastern 

 slopes of Kenia about 2700 m above the sea. 



Chenalopex aegyptiacus (L.). 



Rchw. I, p. 131. 



As soon as we had reached Guaso Nyiri I had the opportunity of shooting a couple 

 of Nile Geese, '%, out of a flock, which rested on a sandbank. At this river these birds 

 were a f amiliar sight even below Chanler Falls, either resting on the sandbanks or flying up 

 and down the river. They were not, however, numerous, and at the other smaller rivers I 

 did not observe any. 



Plectropterus gambensis (L.). 



Rchw. I, p. 134. 



When the Expedition went north during the dry season not a single specimen of 

 Spur Goose was seen, although these big birds are very easily observed. When we passed 

 south, however, along the same road, the rainy season had begun, and then the Spur- 

 Geese were seen almost every day, for instance at Kagio 31 /a, between Fort Hall and 

 Punda Melia V 4 - The following day four specimens were seen flying över a swamp and 

 alighting on a dry grassy slope on the other side not far from Punda Melia. South of Blue 

 Post again a bird of this kind was seen walking around in a moist place 3 A- Next day a 

 Spur-Goose was seen south of Roiru river and so on. It appears evident from this that 

 the Spur-Geese migrate during the dry season to some more suitable locality, but return 

 during the rainy season probably for breeding purposes and then take up their abode 

 near some of the small rivers.
