Zinziri ndi mbalame yaing’ono. Zinziri zazikulu zimatalika pafupifupi 18 centimita ndipo zimalemera pafupifupi 100 magalamu. Zinziri zimapezeka pafupifupi kulikonse ku Ulaya, komanso m’madera ena a ku Africa ndi ku Asia. Monga mbalame zimene zimasamukasamuka, zinziri zathu zimathera m’nyengo yozizira ku Africa yotentha.
M'chilengedwe, zinziri nthawi zambiri zimakhala kutchire ndi madambo. Amadya kwambiri tizilombo, mbewu, ndi tizigawo ting’onoting’ono ta zomera. Oweta ena amasunganso zinziri. Amagwiritsa ntchito mazira awo monga momwe ena amachitira mazira a nkhuku zoweta.
Anthu saona zinziri kawirikawiri chifukwa amakonda kubisala. Komabe, nyimbo yomwe amuna amagwiritsa ntchito pokopa zazikazi imatha kumveka pamtunda wa kilomita imodzi. Nthawi zambiri zinziri zimagonana kamodzi pachaka, mu May kapena June. Nzinzi zazikazi zimaikira mazira asanu ndi awiri mpaka khumi ndi awiri. Zimakwirira zimenezi m’dzenje la nthaka, limene nthiti yaikaziyo imayala ndi masamba a udzu.
Mdani wamkulu wa zinziri ndi munthu chifukwa akuwononga kwambiri malo okhala zinziri. Izi zimachitika polima minda yayikulu paulimi. Poizoni amene alimi ambiri amapopera amawononganso zinziri. Kuonjezera apo, zinzirizi zimasaka anthu ndi mfuti. Nyama ndi mazira awo akhala akuonedwa ngati chakudya chokoma kwa zaka mazana ambiri. Komabe, thupi likhoza kukhala lapoizoni kwa anthu. Zili choncho chifukwa zinziri zimadya zomera zomwe sizingawononge zinzirizo koma zomwe ndi zakupha kwa anthu.
Mu biology, zinziri zimapanga mitundu yawoyawo ya nyama. Zimagwirizana ndi nkhuku, nkhono, ndi Turkey. Pamodzi ndi zamoyo zina zambiri, zimapanga dongosolo la Galliformes. Zinziri ndi mbalame yaying’ono kwambiri motere. Iyenso ndi yekhayo amene ali mbalame yosamukasamuka.
