Key to Checklist:
* indicates a distinct subspecies
"A. The following is a list of the 512 species and 9 sub-species / races of birds recorded from Karnataka.
The number on the left is the serial number of the checklist, while the one after that is the Ripley’s number - according to `A Pictorial Handguide to the birds of Indian Sub-continent’ (Salim Ali and S.Dillon Ripley, BNHS-OUP,1996). Common names of each species as mentioned in PG and recent field guides have been included, to minimise any confusion. "
B. There are some species sighted by some authors but whose distribution falls outside the geographical range of Karnataka. These species are listed below, with their source(s). It becomes essential to reconfirm these sightings.
C. The following is a list of birds which have been sighted by some author/s but whose corresponding names are not found in Salim Ali’s Compact Handguide to the Birds of the Indian sub-continent (used as the standard reference here) or whose given common names do not correspond with the scientific names in the standard reference.
