The crovvn in nine specimens from differenl parts of Siam is ashy brown and does 

 not contrast abruptly with bhe colour of the back and must therofore bolong to the 

 typical race which probably inhabits the Himalayas, Burma, Northern Tenasserim and 

 Northern Siam. In Southern Siam and the Malay Peninsula it is replaced by A. schwaneri 

 which was original ly described from Borneo.

The Verditer Flycatcher was very rare in the Northern parts of the country where 

 only a few specimens were observed during my jonrney. 



In the Siamese Malaya, however, it was more common during my stay there in 

 the cold season. I never saw it in flocks, but always single or in pairs. In habits it closely 

 resembles other Flycatchers and is generally seen perching on dry branches, now and 

 then diving down for a passing insects. It was never observed far inside the thick jungles 

 but frequented the outskirts of forests and sometimes even low secondary jungle.

The Indian Sand Martin was very common and occurred in large flocks along some 

 of the larger rivers of Northern Siam. They were mostly observed flying along the rivers 

 but sometimes they were also seen resting in great numbers on the sandbars in the rivers. 

 These sandbars are only covered with a scanty vegetation of a few low buslies and these 

 bushes were sometimes quite crowded with Sand Martins. More seldom this species 

 occurred at the great swamps of Central Siam and they were never observed nor obtained 

 in the southern districts or in the Siamese Malaya.
