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 Oriolidae (Orioles ) in Sri Lanka.
1) Slender-billed Oriole (Oriolus tenuirostris)
Single sight record at Bundala available according to the Kotagama S. & Ratnavira G (Kotagama S. & Ratnavira G. 2010: 274 Quoting CBCN 2002, Dec: 250). A sight record of single bird on 31st December 2003 at Bundala national park is listed in Appendix 2 (http://www.ceylonbirdclub.org/Appendix-II.pdf) of CBC under the criteria of the report ‘lacks sufficient diagnostic detail or, where necessary, sufficient comparison with ‘confusion’ species or subspecies; and there is therefore doubt as to the identification of the bird concerned’. Neither 2002 nor 2003 annual reviews of CBC notes contain both sight records mentioned above (Siriwardana, U., 2003 & Warakagoda, D., 2004)
