rare bird recorded from Kut Ting wetland

Sterna acuticauda is known from southern China  (previously regular in Yunnan, now very rare) , Pakistan  (frequent in north Sind and Punjab) , India  (widespread and locally fairly common, but some evidence for localised declines) , Nepal  (locally fairly common, declining in some areas) , Bangladesh  (previously common, now a local breeder) , Myanmar  (previously abundant, now a scarce to uncommon resident) , Thailand  (formerly resident in the north-west, now very rare and probably extinct as breeding species) , Laos  (previously bred in large numbers along the Mekong channel, now very rarely recorded) , Cambodia  (in early 1960s the species was apparently fairly common along the Mekong; just two pairs were located in 20031)  and Vietnam  (formerly occurred regularly in Cochinchina, and occasionally in Annam, but there are no recent records) . There has been a decline in South-East Asia and it is now almost extinct in the region. Nevertheless, the suggestion that the world population could be below 10,000 seems unlikely given its status in South Asian countries. Further information on trends and status is needed from elsewhere in the subcontinent. If it appears that the species may have declined by >30% over the last 27 years  (three generations)  then the species would warrant upgrading to Vulnerable.
