During one of my excursions along the coast north from Koh Lak I was lucky in 

 finding a nest of an eagle. The nest was situated ou the upper third of a lairlv high i ree 

 in a mixed bamboo-jungle. When I approached the tree I saw that the eagle was sitting 

 on the eggs and it did not fly away before I made some blows on the tree with my stick. 

 In flying away it started to scream loudly. Unfortunately it was quite inipossible for 

 me or my Dyak collector to climb the tree. Thcrefore I concealed myself near the ])laee 

 in order to shoot one of the parent birds when it returned. I only had to wait about 

 half an hour before it returned and was shot. It tnrned ont to be a fine female specimen 

 of the Changeable Hawk-Eagle. 



The male was also seen, circling high iip in the air, b ut though I waited a consider- 

 able time to get that specimen too it ne ver came into range of my gun. 



The female I obtained does not seem to be a very old bird. It has the lower sur- 

 face with the exception of the lower abdomen and the vent, which are dark brown, white 

 speckled with dark brown; down the throat there is a very distinct blackish brown 

 stripe; head and upper neck tinged with fulvous, all the feathers having broad, dark 

 brown edges; tail-feathers with five dark brown bars and narrowly tipped with white; 

 the subterminal black bar is almost three times as broad as the next one. Upper plumage 

 dark glossy brown, the feathers having white bases which, however, are only visible 

 when the plumage is disarranged. 



258. Circaétus hypoleucus. Pall. — The Short-toed Eagle. 



J* Koh Lak 20 /i 1915. L = 665 mm.; W = 533 mm.; T = 293 mm.; C = 43 mm.; Tarsus = 102 

 mm. — Irides: yellow. Bill: bluish black. Legs: whitish grey. 



A fine female specimen of the Short-toed Eagle was obtained on a sand v somewhat 

 swampy plain near Koh Lak. 



Nowhere else met with during my excursions in Siarn, from where it has not been 

 recorded before. It also seems to be extremely rare in the Malay Peninsnla and only 

 one specimen has been obtained in Selangor. Besides these records a few more speci- 

 mens have been found in the Indian Peninsula and China.
