The crown in nine specimens from different parts of Siam is ashy brown and does 
not contrast abruptly with the colour of the back and must therefore belong 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. schwanert 
which was originally 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 journey. 
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. 
Fam. Hirundinide.

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 bushes 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.
