Birds that appear outside their normal range are known as vagrants. This post listed up to date published sight records of the single *unconfirmed vagrant of the family Turnicidae (Buttonquails) in Sri Lanka.
1) Small Buttonquail (Turnix sylvaticus dussumier)
Single sight record from the Buttuwa wewa area of the Yala national park in February 1978 by Dr. Ben King, an American ornithologist, is the only record of the occurrence of this bird in Sri Lanka (Hoffmann, T. W. 1979 & Hoffmann, T. W., 1978)
Hoffmann, T. W., 1979. Note from the Ceylon Bird club 1978. Loris, 15(1), p 6-8.
