Khao Dinsor - Chumphon Raptor Centre
Khao Dinsor was placed firmly on the birding map when, in 2008, it was realised that large numbers of raptors pass close to and along the ridge on their southward, autumn, migration between mid August and mid November. In the years since, a raptor centre - for educational purposes - has been constructed, and each year in mid to late October a Raptor Migration Weekend is held. Volunteers, observing the migration, are present yearly with all of September and October monitored. Migration varies with month, and on a day to day basis, heavily dependent on wind, cloud cover and rain. It is estimated that somewhere between 250,000 - 500,000 raptors, of more than 25 species, pass annually. In addition, each year several species, rarely recorded in Thailand, turn up. Other migrants also pass through with all three species of needletail recorded.
