face (extending well behind the eyes) is bright red; legs 
reddish. When flying, the white plumage displays a 
slight pinkish tinge, like that of a flamingo, but less 
pronounced. Nests on trees. 
Geese 
Spur-winged Goose— Plectropterus gambensis. A huge species, 
black and white, common and widely distributed. Fre¬ 
quents marshy plains and foreshores, feeding by day, and 
flighting to open waters at sundown to roost—as our 
European geese do. 
Egyptian Goose— Chenalopex cegyptiacus. Frequently met with 
on the driest grass-prairies by day; also on Lake Elmen- 
teita both by day and night. 
Pigmy Goose— Nettopus auritus . At Kisumu, on Victoria 
Nyanza, frequenting the lily-lined shores. 
Ducks 
Knob-billed Duck— Sccrcidiornis melanonota. A large species, 
equal in bulk to many of the Geese, and sometimes called 
the Black-backed Goose. Found on Naivasha, and the 
commonest of all the ducks on Lake Baringo. 
White-faced Tree-Duck— Dendrocycna viduata. This is one of 
the group known as “ Whistling Teal,” some of which also 
frequent the coast. Two species, of which D. viduata is 
one, are found on Baringo, the other being probably the 
Whistling Duck— D. fidva. [Note.—This Duck is found 
spread over four continents, to wit: both North and 
South America, great part of Africa (including' Mada¬ 
gascar), and, in Asia, throughout India, Ceylon and 
Burmab. 
Its congener last named, D. viduata , is also a New- 
World species, inhabiting South America as well as Africa. 
But both strictly avoid Europe.] 
Yellow-bill, or African Mallard— Anas undulata. Common in 
East Africa and southwards to the Cape Colony. It fre¬ 
quents lakes, such as Elmenteita, in big packs, and 
“flights” regularly at dusk and dawn, often accompanied 
by Pintail, Shoveler, etc.
