Noog yog ib pawg ntawm cov vertebrates uas muaj kev sib raug zoo nrog tib neeg rau ntau pua xyoo. Txawm hais tias muaj ntau qhov kev tsis sib haum xeeb rau lawv qhov kev faib tawm, feem ntau, kev sau se ib txwm suav tias lawv yog cov chav kawm Aves. Lub caij no, rau phylogenetic systematics lawv suav nrog hauv Archosaurs, uas tam sim no lawv koom nrog khej.
Muaj ntau txhiab hom noog, uas nyob hauv ntau qhov chaw, ob qho tib si hauv av thiab hauv dej. Nws yog qhov tshwm sim heev rau cov noog ua rau peb xav tsis thoob nrog lawv cov nkauj, cov qauv davhlau thiab plumage. Tag nrho cov no undoubtedly ua rau lawv heev striking tsiaj. Txawm li cas los xij, nyob rau hauv pab pawg no muaj ntau haiv neeg, uas qee zaum tuaj yeem ua rau qee qhov tsis meej pem rau lawv qhov kev txheeb xyuas. Tias yog vim li cas hauv tsab xov xwm no ntawm peb lub xaib, peb nthuav qhia sib txawv ntawm goose, goose, swan thiab duck, sib txawv noog uas ua rau qhuas rau lawv lub koob meej. Ua tsaug!
Cov noog no tau muab faib ua taxonomically li cas? Nws yog ib qho tseem ceeb uas yuav tsum tau hais tias oca thiab goose yog ob lub npe hu ua tib hom Yog li no, hauv tsab xov xwm no peb yuav tsis hais txog qhov sib txawv ntawm goose thiab goose, tab sis peb yuav tsom mus rau cov yam ntxwv tshwj xeeb uas muaj nyob nruab nrab ntawm duck, swan thiab goose lossis goose.
