Collared Pratincole in Thailand?

A pratincole spp. showing a white-trailing edge to the wing, and other features supportive of Collared Pratincole was seen at Wat Komnaran (nr Laem Pak Bia) by visiting birders on 22nd January.  It has apparently been seen again this morning...

A broad white-trailing edge to the wing is considered by Driessens & Svensson (2005) to be a clinching feature of Collared Pratincole, so this bird sounds very interesting.  Apparently there is a small population of Collared Prats that breeds in Pakistan and winters in western India where they may come into contact with Oriental Pratincoles (all other Collareds winter in Africa).  There is apparently a record of a vagrant Collared from Sri Lanka and also from the Chagos Islands (500 mile south of the Maldives), so a bird appearing in Thailand is not beyond the realms of possibility.
