This is a list of the bird species recorded in Bangladesh. The avifauna of Bangladesh include a total of 466 species, of which one has been introduced by humans, and twelve are rare or accidental. Three species listed are extirpated in Bangladesh and are not included in the species count. Thirty-five species are globally threatened. This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of ''The Clements Checklist of Birds of the World'', 5th edition. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account. Introduced and accidental species are included in the total counts for Bangladesh. The following tags have been used to highlight several categories. The commonly occurring native species do not fall into any of these categories. * (A) Accidental - a species that rarely or accidentally occurs in Bangladesh * (I) Introduced - a species introduced to Bangladesh as a consequence, direct or indirect, of human actions * (Ex) Extirpated - a species that no longer occurs in Bangladesh although populations exist elsewhere __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 2 species which occur in Bangladesh. *Little grebe, ''Tachybaptus ruficollis'' *Great crested grebe, ''Podiceps cristatus'' 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 Bangladesh」の詳細全文を読む スポンサード リンク
