The Oriental Bird Club (OBC) "is for birders and ornithologists around the world who are interested in birds of the Oriental region and their conservation."
The geographical area covered by the OBC is bounded in the west by the Indus river, Pakistan through India and south-east Asia; in the east by the Wallacea line, East Indonesia; Mongolia, north-east Russia (E of 90°E) and Japan in the north; and the Lesser Sundas and Christmas Island in the south. Within BUBO Listing, the OBC authority can be applied to lists for this Oriental region as well as certain countries therein. (We will be introducing more countries gradually.)
The OBC published An Annotated Checklist of the Birds of the Oriental Region in 1996 and provides an update to this on their website. This is the most up to date "official" list but there have been several taxonomic changes and new species discoveries since then. Hence BUBO Listing is using an "unofficial" OBC checklist, applying generally accepted recent changes. This list was kindly supplied by Krys Kazmierczak and is as used on Oriental Bird Images. BUBO Listing will update this as soon as another update is available from the OBC.
For countries within the Oriental region that do not have a specific authority of their own (e.g. India), BUBO Listing uses an appropriate subset of this OBC List based largely on the distribution data provided by Clements and Avibase: if you notice any omissions or errors with these OBC country lists then please let us know.
July 2020: The OBC list does not seem to be maintained by OBC any more, and has not had recent, generally accepted, taxonomic changes applied. Therefore, we are no longer supporting it on BUBO Listing, for the Oriental region or individual countries within. We recommend listers use IOC instead.
