The Indian state of Karnataka has about 521 bird species within its boundaries. The following list of birds is based on multiple sources and incorporates recent taxonomic revisions. Species which are considered provisional, introduced or escapees are mentioned, but are not considered in the count. The birds of some parts of Karnataka have been well studied. Uttara Kannada (known as North Kanara) district was surveyed by James Davidson 〔 for five years between 1888 and 1896 (341 species) while parts of this district along with several sites in Belgaum district were covered for three months by Walter Norman Koelz in 1938 (232 species).〔 Salim Ali, in his historic survey of Mysore state (343 species), covered much of southern and central Karnataka and Major Phythian-Adams covered parts of Mysore and provided the only records of several uncommon species.〔"Ali & Whistler (1942-43) has observed that besides an article by Phythian-Adams (1940 &1948), no literature is available extensively on birds from present study area"--(Birds of Mysore Area )〕 Frederick Nicholson Betts covered Kodagu (Coorg) district, then disjunct from Mysore, and provides good documentation of several birds (279 species) of the Western Ghats. Hence, by 1970, when modern field ornithology and amateur bird-watching were popularised through the ''Newsletter for Birdwatchers'', a moderate level of documentation had taken place in several parts of Karnataka. The only grey area that remained unexplored was the north eastern parts of the state, which was part of the state of Hyderabad then. Salim Ali, during this Hyderabad State Ornithology Survey, could not visit these parts as the survey had to be cut short due to financial challenges. __NOTOC__ ==Grebes== Order: PodicipediformesFamily: Podicipedidae Grebes are small to medium-large freshwater diving birds. They have lobed toes and are excellent swimmers and divers. However, they have their feet placed far back on the body, making them quite ungainly on land. There are 20 species worldwide and 5 species which occur in India and 1 in Karnataka *Little grebe, ''Tachybaptus ruficollis'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of birds of Karnataka」の詳細全文を読む スポンサード リンク
