This species, which inhabits India to tlie Malay Peninsula, Southern China, 

 Hainan and Formosa, is closely allied to Halcyon smyrnensis L. but differs from 

 that bird in being smaller and of brighter colours.

111. Halcyon pileata Bodd. — The Black-capped Kingfisher was fairly com- 

 mon everywhere in favourable localities and occurred in great numbers along the 

 »klongs» in Bangkok and its eiivirons. As far nortli as along the Meh Lem river 

 it was also found though less frequently than in the southern and central districts 

 of Upper Siam.

112. Dichoceros bicornis L. — The Great Hornbill is a real inhabitant of 

 the dense primeval evergreen forests and also one of the most characteristic. In the 

 environs of Bång Hue Hom and Kao Plyng they were very common and were always 

 seen in pairs or in small flocks of about four or five individuals. 



Ovving to their habit of always keeping up in the highest trees they are rather 

 bard to get and besides this they are exceedingly wary. 



The best way to get a hornbill is to wait under a tree bearing such fruit that 

 they like and from which they moved at one's approach. 



In the forests round Sriracha and Nong Koh they were also not uncommon 

 and here I found a nest containing youngs at the end of April. 



When flying they make a great noice with their wings which is an alternation 

 of a series of flappings of the wings and of sailing with the wings motionless and 

 when flying they generally are very high up in tlie air. 



113. Anthracoceros albirostris Shaw & Nodder. — This Hornbill was observed 

 in flocks up in the dense evergreen hill forests round Bång Hue Hom and the Meh 

 Lem and Meh Song rivers in Northern Siam. In all these places it was very com- 

 mon and its harsh woodpecker-like cry echoed through the woods now and then. 

 When flying it always flaps with the wings for some time and then rests on the 

 wings without moving them. Like the other Hornbills which I found in Siam, this
