The Burmese Shikra occurs throughout Siam and was even found as far south as 
Koh Lak in the Siamese Malaya, but down there it seems to be rather scarce and only a 
few specimens were observed. Most abundant it is, however, in the open deciduous forests 
in the Northern Districts. Their food chiefly consists of insects which they catch on 
the wing.

Horsfied’s Short-toed Hawk, which breeds in parts of China, is only to be 
considered as a winter visitor to Siam, where it also seems to be extremely rare. During 
my journey I only obtained a single specimen, which was shot at Pak Koh in Northern 
Siam on the 14th of April 1914. When observed it was perching on a bamboo-clump 
near the banks of an almost dry creek and was easily stalked and shot. 
As far as I know, this species has not been recorded from Northern Siam before, but 
Rosinson & Kuoss records it from the island of Langkawi. In the Malay Peninsula 
it is stated by the same authors as being very rare.

This species is probably only a winter visitor to Siam, though young specimens 
may occur during the summer. 
Outside Siamese Territory it has been found during the cold season in Southern 
China, Hainan, Formosa, the Malay Peninsula and some of the Gr. Sunda Islands. 
In Siam it was by no means common, and I never succeeded in shooting any fully 
adult specimens. It resembles Astur badius poliopsis, HuME in the general tone of its 
plumage, but it has the toes longer and more feeble than that species. Another 
allied bird is Accipiter virgatus TEmMM. which inhabits Java, Borneo, Sumatra and some 
of the Sunda Islands.

A fine female specimen in adult, though rather abraded plumage, was shot near 
Koh Lak on the 30th of November 1914.
