The white-eyed river martin was seen in Thailand in 1972, 1977 and 1980, but not definitely since. There are unconfirmed sightings from Thailand in 1986 and Cambodia in 2004. It is classified as critically endangered by the International Union for the Conservation of Nature and Natural Resources (IUCN). This designation means that a species' numbers have decreased, or will decrease, by 80% within three generations. This species may be extinct, but the IUCN will not categorise it as such until extensive targeted surveys have been conducted. Despite legal protection under Appendix 1 of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) agreement, it was captured by locals along with other swallows for sale as food or for release by devout Buddhists. Following its discovery by ornithologists, trappers were reported to have caught as many as 120 and sold them to the director of the Nakhon Sawan Fisheries Station who was unable to keep them alive in captivity. The small population may therefore have become non-viable.
