Izi ndi zimbudzi zokhala ndi milomo yowongoka, khosi lakuda ndi mitu "yayitali". Nthawi yoswana, imakhala ndi khosi lofiira ndi mimba, misana yakuda ndi mitu yakuda yokhala ndi malo achikasu olimba kuchokera kudiso lililonse mpaka kumbuyo kwa mutu. Mbalame zachinyamata zimakhala zachikasu, theka lakumunsi la mutu ndi loyera. Akuluakulu osabereka ndi otuwa-akuda ndi oyera pansi pamutu ndi m'khosi.
Chikhalidwe
M'nyengo yozizira, mtundu wa khosi lofiira umapezeka m'madzi amchere m'mapanga a m'mphepete mwa nyanja ndi m'mbali mwa nyanja, makamaka m'madzi abwino. Munthawi yodzala, amakhala m'madzi okhala ndi madzi osakanikirana ndi madambo.
Mbalameyi imapezeka kwambiri kumadera otentha a Eurasia ndi North America. Mkati mwa European Union, mitunduyo imaswana ku Scotland kokha, komwe kuli mitundu 60 ya awiriawiri. Chiwerengero chonse cha ma grebes a khosi lofiira kumpoto kwa Europe akuyerekeza kuti ndi 6,000-9,000 oweta awiriawiri m'mphepete mwa Nyanja ya North ndi m'madzi a Central Europe. Nthawi zina mbalame zimauluka kupita kunyanja ya Mediterranean. Ngakhale kusinthasintha kwakomwe kuderalo, mitundu yonse yamtunduwu ndiyokhazikika.
Zomwe zimadya
M'nyengo yotentha, mbalame zimadya tizilombo komanso tizinyama tina ting'onoting'ono tomwe timagwira pansi pamadzi. M'nyengo yozizira, amadya nsomba, nkhanu, nkhono ndi tizilombo.
Kukhazikitsa ma grebes a khosi lofiira
Pamodzi, amuna ndi akazi amamanga chisa, chomwe ndi mulu woyandama wa chomera chonyowa chomangika kuzomera zomerazo. Mkazi amaikira mazira anayi mpaka asanu ndipo banjali limafungatira mazirawo masiku 22-25. Makolo onse amadyetsa anawo, amayamba kusambira atangobadwa kumene ndikukwera pamsana pa makolo. Pakumizidwa kwa mphini pansi pamadzi, anapiye amakhala kumbuyo kwawo ndikutuluka, atagwira mwamphamvu nthenga. Zinyama zazing'ono zimauluka pambuyo pa masiku 55 mpaka 60 amoyo.
Kusamuka
Nyengo yozizira ikamayandikira, mbalame zimasiya zisa zawo ndikupita kunyanja ndi nyanja zazikulu. Kusuntha kwadzinja kumayamba kumapeto kwa Ogasiti, pachimake mu Okutobala-Novembala. Ma grebes okhala ndi khosi lofiira amatuluka m'malo achisanu kuti apange mazira mu Marichi-Epulo. Amafika pamalo omwe amaikira mazira, koma samamanga zisa mpaka madziwo atakhala opanda ayezi.
Zosangalatsa
Golo wofiirira wofiira amadya nthenga zake, samakumbidwa, amapanga mphasa m'mimba. Nthenga zimakhulupirira kuti zimateteza m'mimba ku mafupa akuthwa a nsomba mukamadya. Makolo amaperekanso nyama zina ndi nthenga.
