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 on the upper third of a fairly high tree 
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 impossible for 
me or my Dyak collector to climb the tree. Therefore I concealed myself near the place 
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 turned out to be a fine female sperbnen 
of the Changeable Hawk-Eagle. 
The male was also seen, circling high up in the air, but though I waited a consider- 
able time to get that specimen too it never 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.

mm. — Irides: yellow. Bill: bluish black. Legs: whitish grey. 
A fine female specimen of the Short-toed Eagle was obtained on a sandy somewhat 
swampy plain near Koh Lak. 
Nowhere else met with during my excursions in Siam, from where it has not been 
recorded before. It also seems to be extremely rare in the Malay Peninsula 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.
