Inyoni

Izinyoni ziyiqembu lama-i-theropod dinosaur zinegazi elifudumele elakha isigaba se-Aves, esiphawuleka ngezimpaphe, imihlathi engenamazinyo, ukuzalela amaqanda anegobolondo eliqinile. Isilinganiso esiphakeme sokudla, inhliziyo enamagumbi amane, kanye namathambo aqinile kodwa alula. i-moa">Izinyoni ziphila emhlabeni wonke futhi zihluka ngobukhulu kusuka ku-5.5   i-bee hummingbird kuya ku-2.8    i'ostrich ejwayelekile. Kunezinhlobo ezingaphezu kuka-11,000 eziphilayo futhi zihlukaniswe ngamaqembu angu-44. Abangaphezu kwengxenye yizinyoni ze-I-passerine noma "ezihlala phansi". Izinyoni zinezimpiko ezikhulayo ezihlukahluka kuye ngezinhlobo  okuwukuphela kwamaqembu aziwayo angenamaphiko ama-moa kanye Izinyoni zezindlovu ezingasekho. Amaphiko, nemilenze yangaphambili eshintshiwe, anikeza izinyoni ikhono lokundiza. Yize ukuguquka okuqhubekayo kuholele ekulahlekelweni ukundiza kwezinye izinyoni. Kufaka phakathi ama-ratite, Ama-penguin, nezinhlobo ezahluka hlukene zeziqhingi. Izimiso zokugaya ukudla nokuphefumula kwezinyoni nazo zivumelana ngokukhethekile nokundiza. Ezinye izinhlobo izinyoni zasemanzini, ikakhulukazi izinyoni zasolwandle nezinye izinyoni zamanzi, zike zathuthuka kakhulu ekubhukudeni. Ucwaningo lwezinyoni lubizwa ngokuthi i-ornithology.

Izinyoni zivela kuma-theropod angaphambili, ngakho-ke zakha ukuphela kwezibanikazi ezesabekayo ezaziwayo. Ngokufanayo izinyoni zibhekwa njengezilwane ezihuquzelayo ngomqondo wesimanje we-I-cladistic waleli gama, futhi iznhlobo zazo eziseduze eziphilayo Izingwenya. Izinyoni ziyinzalo ye-avialans yasemandulo (amalungu ayo ahlanganisa I-archaeopteryx) eyavela okokuqala ngesikhathi se-I-Jurassic Yokugcina. Ngokulinganisela okuthile, izinyoni zanamuhla (i-Neornithes) zavela ku-(Late Cretaceous) noma phakathi kwe (Early and Late Cretaceus) (100 Ma) futhi zahlukahluka kakhulu ngesikhathi se(-Cretaceous-Paleogene extinction event) eminyakeni eyizigidi ezingama-66 endlule, eyabulala Ama-pterosaur nazo zonke izibankwakazi ezesabekayo ezingezona ama-i-ornithuran.

Izinhlobo eziningi zezenhlalo zilondoloza ulwazi kuzo zonke izizinkulwane (isiko). Izinyoni zisebenza ngobungani zikhulumisana ngezimpawu ezibonakalayo. Izingoma, futhi zihlanganyele ekuziphatheni okufana ukuzalanisa ngokubambisana nokuzingela, ukuqoqa, nokuxhaswa kwezilwane ezizingelayo. Iningi lezinhlobo zezinyoni ezomphakathi kodwa hhayi ngokobulili zinomfazi oyedwa.Ngokuvamile inkathi iyodwa yokuzalela ngezinye izikhathi zeminyaka, futhi akuvamile ukuphila. Ezinye izinhlobo zinezinhlelo zokuzalanisa ezingezona ezeduna. Iduna elilodwa namasikazi amaziningi noma, ngokungavamile, ezingezona ezingamaduna amaningi. Izinyoni zikhiqiza abantwana ngokuzalela amaqanda avundiswa ngokuzala ngokobulili. Ngokuvamile zizalelwa esidlekeni bese zifukanyelwa abazali. Izinyoni eziningi zinenkathi ende yokunakekelwa abazali ngemuva kokuchanyiselwa.
