CITES Appendix I. Beung Boraphet has been declared as a Non-Hunting Area. Several unsuccessful searches have been made for it at this site since its discovery. In 1969, a survey, based on village interviews, of the Nan Yom and Wang rivers in northern Thailand did not reveal any further information. Similarly, a brief survey in 1996 of rivers in northern Laos was unsuccessful, and in 2008 a BirdLife/RSPB funded project consisting of speedboat surveys and village interviews at the site of the 2004 claim in Cambodia also proved fruitless (Seng Kim Hout 2008). The area is frequently visited by birdwatchers who have failed to record the species in the 21st century (eBird 2021).Conservation Actions Proposed
Conduct a media campaign to trace potential sightings by local people to focus survey efforts. Conduct surveys for the species along all major rivers within its putative range (particularly northern Thailand and Myanmar, but also potentially southern China, Laos, and Cambodia) and search alternative habitats such as forests and limestone cave systems (Tobias 2000, BirdLife International 2001). If a population is rediscovered, immediately implement appropriate conservation measures.
Location InformationEurochelidon sirintarae is only known as a probable non-breeding visitor to one area of central Thailand (BirdLife International 2001). It was discovered in 1968, at or near Bueng Boraphet lake, near the town of Nakhon Sawan. It is known from 12 specimens collected amongst roosts of wintering hirundines, with rumours of many more sold in local markets, a possible field observation at Bueng Boraphet in 1978, and two unconfirmed reports, the last of which was in 1986 (Tobias 2000). Its population must be tiny and the lack of reliable records for over 35 years strongly suggests that it has undergone a decline. The species may be extant within South-East Asia, where survey effort has increased in recent years. Searches in the Sre Ambel area of Cambodia in March-April 2008 failed to find the species, and the habitat was degraded and apparently unsuitable (Seng Kim Hout 2008). Myanmar may be a more likely refuge of any remaining population.
