Drono^os were the first birds to come and after a little while they could be counted 

 nearly by hundreds, Then tliey were not at all shy, which, however, I must say 

 they were on other occasions. Sometimes I even found theni in the evergreen forests 

 far from any clearings but this was only exceptional. As a rule they were most 

 frequently met with in the bamboojungles and in the dry forests, especially where 

 there were thick bushes to conceal in. Among the great flocks of Laughing Thrushes 

 {Garrulax diardi Less. & Garridax moniliger Hodgs.) there were also always some 

 Racket-tailed Drongos too. 



Several subspecies of this bird have been described but the first-named form 

 is the Siamese one which is distinguished by its smaller size and smaller cr^st. This 

 form inhabits Siam to the Malay Peninsula, Sumatra, Java and Borneo.

34. Orthotomus atrigularis Temm. — Very common in every part of the country 

 where there was brushwood and dense undergrowth. In the primeval forests it also 

 occurred, though more rarely than in the old clearings where this species was very 

 abundant.

35. Lusciniola aédon Pall. — This bird is only a winter visitor in Eastern 

 Asia, its breeding places are to be found in Northern China and Siberia. During the 

 journey I only shot a single specimen near the village of Den Chai. When I 

 passed through a place in the dry forests which was richly covered by a dense 

 vegetation of higli grass and plants I was attracted by the beautiful song of the 

 Tick-billed Warbler. 



36. Phylloscopus nitidus plumbeitarsus Swinh. — Very common during the 

 winter months both in Eastern and Northern Siam, but never in the evergreen forests. 



37. Phylloscopus superciliosa Gm. — Winter visitor only. In the collection 

 there are three specimens, one from Bangkok, one from Sakerat and one from Den
