CURRENT STATUS OF BOOTED EAGLE HIERAAETUS PENNATUS IN THAILAND

Booted Eagle Hieraaetuspennatus, a medium-sized eagle, is considered to be a rare passage migrant, winter visitor or even a vagrant in Thailand, according to widely-used field guides. Nation-wide raptor censuses in winter, organized by Thai Raptor Group (TRG) and volunteered by avocational birders, revealed that the species was more common than previously thought, particularly in suitable habitats. Its winter range covers four regions of Thailand, including North-west, North-east, the central plains and southern provinces.

ECOLOGY OF WILDLIFE CORRIDOR DESIGN : initial concepts for Thailand

Corridors have been adopted worldwide and now serve as a crucial tool for wildlife conservation planning by reducing the effects of habitat fragmentation. During the past several decades wildlife habitat in Thailand has become increasingly fragmented, potentially resulting in inbreeding and resource limitations for many species.  As a result, research scientists and land managers are paying serious attention to the idea of using corridors for wildlife conservation in Thailand.  However, the concept of using corridors for landscape linkage in Thailand requires further development, and in order to use corridors to conserve wildlife in Thailand careful planning and additional in-country research will be necessary.

Study and conservation of Varanids of Thailand

Varanids are lizards of the Varanus genus, the largest lizards of Thailand.  In Thailand, there are four taxa of Varanids: Varanus bengalensis nebulosus, Varanus dumerilii, Varanus rudicollis and Varanus salvator macromaculatus.  A fifth species of monitor was documented in Thailand, Varanus flavescens (Boulenger, 1912) in Trang; however, this account and others in peninsular Malaysia appear to have been Varanus bengalensis nebulosus.

 Little study has been done of Thailand?s Varanids. The protection given by the Wildlife Reservation and Protection Act BE 2535 (1992) which has helped in the conservation of the genus Varanus has also greatly hindered their study. On top of the protection law hindering research, regulations concerning the use of radio frequencies and the accompanying bureaucracy that accompanies the regulations greatly hinder the use of radio transmitters which are needed for a comprehensive study of Varanid ecology.  Over the two decades since this protection has been afforded, only Lauprasert & Thirakupt (2001) represents a published large scale monitor specific study.

REPRODUCTIVE CYCLE OF THE RAINBOW WATER SNAKE

From March 2006 to April 2007, two hundred and fifty eight Enhydris enhydris females at Ban Borthong, Kabinburi District, Prachinburi Province, were collected from local fisherman?s nets for the investigation of reproductive cycle. Thirty-nine gravid females were found during nine-month period,  February to October, from which the number of gravid females was highest in April.
