sound caused by the flapping of their wings when they mooved from one tree to 

 another. In some of tlie smaller trees I once had the good fortune to catch sight 

 of a couple of broadbills {Serilophus lunatus Gould.) showing no signs of fear. These 

 curioiis birds are only to be found in the evergreen forests, but in Siam they seemed 

 to be very rare. More often I caught a glimpse of the yellow breast of a Trogon 

 (Harjmctes oreskios Temm.) before it disappeared in the gloom of the forest with a 

 fiight resembUng that of a cuckoo. Here and there were old clearings with only a 

 few trees left, and on these I could be pretty sure to find a small flock of the In- 

 dian Grackle {Eulabes intermedia A. Hay.). The birds were not at all difficult to 

 discover with their beautifnl glossy-black plumage, which together with the yellow 

 earlappets were sharply outlined against the green foliage. In the same localities I 

 could perhaps also catch sight of the Fairy Blue-bird {Irena puella Lath.) perform- 

 ing aerial evolutions in chase of passing insects, or flocks of Pigeons {Treron nepal- 

 ensis Hodgs. and Osmofreron phayrei Blyth.) with rattling wings move away to 

 a more quiet place in the väst jungles. The silence was now and then disturbed 

 by the tapping of a woodpecker {Mulleripicus pulverulentus harterti Hesse.) or by 

 the crowing of a wild fowl {Gallus ferrugineus Blyth.) but to catch sight of especi- 

 ally the last-mentioned was easier said than done. 



Several small creeks and rivulets traverse the hill forests in all directions and 

 along these the vegetation was much richer if possible. The Spider hunters {Arach- 

 nothera magna Hodgs. & Ärachnothera longirostris Lath.) frequently used such pla- 

 ces as their hiinting grounds and were busy searching the leaves and flowers for 

 food, while the beautiful coloured Sun-birds {Aetlwpijga cara Hume.) were fluttering 

 like butterflies from flower to flower. In the thickest shrubs tailor-birds {Orihotomus 

 atrigularis Temm.) and Black-throated Babblers {Stachyrhis nigriceps Hodgs.) were 

 scurrying like råts, while the black and white Magpie-Robin {Copsychis saularis L.), 

 at the slightest sign of danger, at once dived into the tangle.
