very similar. The males are not difficult to identify, but the females often resemble 
one another very closely. Writing of S. sphenwrus, My. Oates says that it is found 
in the thick forest country of Burma, frequenting trees which bear fruit, and going 
about in flocks. It is a summer visitor to the Himalaya, and breeds from April to 
July, constructing a nest of twigs on the outer branches of trees. In October it 
collects in small flocks of six or eight, and quits the country. It is rather 
shy, and its note is a soft, cooing whistle ; its food consisting entirely of small fruits, 
which are swallowed whole.

ABYSSINIAN WALIA-PIGEON, 
The African genus Vinago has the tail-feathers almost even, 
the outer pair being little shorter than the middle, and the feathers 
on the legs conspicuously yellow, while the forehead in some species is more or less 
naked, The Abyssinian walia (V. walia) is met with in the subtropical belt, and 
rarely seen on the highlands, being first observed at an elevation of about two 
thousand feet, and not extending above six thousand. Its call is a liquid whistle, 
very similar to that of the Indian green pigeon in tone, but with the concluding 
portion a little harsher and more prolonged. It feeds on fruits, especially figs, 
and, like its allies, is delicious eating. A third genus (Crocopus) inhabiting the 
Indo-Chinese countries resembles Vinago in having the feathers on the legs 
yellow, but is distinguished by the first three flight-feathers being pointed. The
