THE BIRDS OF SINGAPORE ISLAND 
''imperial pigeon" very much like the "'pcrgam** of the Malays 
hut coppery rather than green in plunjage; a large j?reen 
l>ig:eon with a very thick bill, a true denizen of the jungle; 
certain long-tailed green pigeons (Sphenoccrcus). two 
Cuckoo-doves (Macropygia) and one or two others. 
The author's list of Singapore birds contains the names of 
no less than ten different pigeons and unlike some of the birds 
listed therein all of these have a fair claim to be included in the 
Singapore avifauna, for of nine of them freshly killed specimens 
have been examined and the tenth certainly occurs as we have 
seen specimens in various localities on the island. The 
situation therefore calls for drastic treatment if 'this book is 
to be kept within reasonable limits and a few of the species 
less likely to be met with must be dismissed in a few lines.
