Ensimini ye-USSR yangaphambili, izimungulu zihlala emgodini wengalo yase-Ural nasemachibini ngamanye nasemachibini aseKazakhstan. Ezingxenyeni eziningi zeYurophu, le nyoni ifuywa. Endle, izinyoni zikhetha izindawo ezingavakashelwa ngabantu - amachibi nezizalo zemifula, indawo yayo egcwele uhlaza, amaxhaphozi.
Ngenxa yemizamo yabantu, kunabantu abancane e-Australia, eNyakatho Melika, eNew Zealand nasezwenikazi lase-Afrika. Ama-swans amaningi athanjisiwe noma ahlanganyele ngokuzithandela, njengezinyoni zokuhlobisa emapaki wedolobha.
Izinyoni zihlala ezindaweni ezingaphezu kwamamitha angu-500 ngaphezu kolwandle. Kungaba futhi imifula yemifula, imizimba yamanzi amasha, amatheku olwandle. Izidleke zamaSwans ogwini lwaseBaltic, i-Atlantic ne-Asia. Ngemuva kokukhula, inzalo iya olwandle lwaseCaspian naseBlack. Izinyoni zingahlala ezidlekeni zazo, bese abantu bezondla.
Ngesikhathi sasebusika, zihlangana zibe amakoloni amancane. Uma elinye lamalungu omhlambi ligula futhi lingakwazi ukundiza, amanye ahlehlisa indiza kuze kube yilapho lowo ogulayo elulama. Ebusika, izimpaphe zezinyoni zihlala zimhlophe, lapho zindiza ziye endaweni efudumele, ziba mnyama.

Uncamela ukudla okunezimpaphe zemvelaphi yezitshalo. Ukudla kwezingulube ezikhulele endle kuhlukile kokwezinyoni ezifuywayo.
I-swan isimungulu iyadla:
- izimpande;
- izingxenye zezitshalo ezingaphansi kwamanzi;
- ama-rhizomes;
- chara kanye ulwelwesi filamentous.
Uma izitshalo ziqukethe ama-crustaceans amancane nama-molluscs, nazo ziba ukudla kwama-swans. Ngenxa yezintamo zazo ezinde, izinyoni zingacwilisa emanzini ziye ekujuleni kwemitha elilodwa. Njengamadada, bacwilisa ikhanda, intamo nengaphambili lomzimba emanzini, beme bemi emanzini bese befika ezansi ngoqhwaku lwabo. Emhlabathini, ama-swans adla amaqabunga nezinhlamvu.
Lapho kudilika, izingxenye ezincane zezitshalo ziyasuswa, amaphuphu adla kuzo. Ngesikhathi sasebusika, ulwelwe lusetshenziswa kakhulu njengokudla. Ngenxa yesiphepho nokwenyuka kwamanzi, kuba nzima kakhulu ukuthola ukudla. Zibe sezilamba futhi zikhathele kuze kube sezingeni lokuthi zingakwazi ukundiza. Kepha, noma kunjalo, abazishiyi izidleke zabo balinde isimo sezulu esihle.
Abantu ngaso sonke isikhathi balwela ukondla izindlebe eziyizimungulu ngesinkwa, kepha lokhu akunakwenzeka nakancane. Isisu sezinyoni asisetshenziselwa ukudla okunjalo. Ngemuva kokudla isinkwa esivuvukile, ama-swans angagula futhi afe. Ngasikhathi sinye, ukondla okusanhlamvu kungasindisa izinyoni endlaleni ebusika. Bangadla kuze kufike ku-4 kg wokusanhlamvu ngosuku.

Bangakwazi ukuzixazulula zombili kumakholoni futhi ngokwehlukana. Bahlukaniswe yimvelo enokuthula, babonisa ulaka kuphela lapho bevikela indawo. Lapho ingozi isondela, izinyoni zigobisa izintamo zazo, zibhidlize izimpaphe zazo bese zibhukuda zibheke kulowo ezingamazi. Ngesikhathi sokulwa, bashaya kakhulu ngemilomo yabo. Kungenzeka ukuthi ulimale kanzima ngokuba nentshisekelo eyeqile ekubumbeni.
Uma kungekho muntu ohlupha isidleke, ama-swans abambelela lapho ahlala khona kuze kube sekugcineni futhi awushiye kuphela lapho ichibi selifriziwe ngokuphelele. Imvamisa indiza iqala ukuphela kukaSepthemba enyakatho nango-Okthoba eningizimu yebanga. Izinyoni zindiza ubusuku nemini. Impempe yempiko yemhlambi isabalala kakhulu. Zindiza kulayini oblique, zisho ukumemeza okuhoshozelayo.
Ngesikhathi sasebusika, izimungulu zihlala ngazimbili esezakhiwe kakade. Abantu abanesizungu bayabazi abalingani futhi bangene emishadweni yemishado. Kusukela eminyakeni emibili swans molt kabili ngonyaka. Ngesikhathi se-molt egcwele ehlobo, izinyoni ziphelelwa amandla okundiza. Ngalesi sikhathi, abazali bavele banakekele amaphuphu futhi abakwazi ukuwashiya lapho bekhathazekile.
Kukhona inganekwane eyaziwayo mayelana nokuthembeka kwe-swan. Ithi uma omunye wabalingani efa, khona-ke omunye akasafuni izithandani. Lokhu akulona iqiniso ngokuphelele. Ngempela, izinyoni zihlala nomlingani oyedwa kukho konke ukuphila kwazo. Kepha, uma efa, owesibili ufuna umbhangqwana omusha.
Naphezu kobukhulu obumangalisayo, izimungulu zindiza kahle. Ngesikhathi sokufuduka, angahlangana abe amakoloni ezinkulungwane ukugwema ukuhlaselwa yizilwane ezizingelayo. AmaSwans awazi ukuthi angasuka kanjani emhlabeni. Lokhu kwenzeka kuphela emanzini futhi ngokuhamba kwesikhathi.

Ngenxa yokushushiswa ngabantu, imindeni ingaqhekeka futhi baningi kakhulu abesilisa abangashadile, ngenxa yalokho abazama ukudikibala abesifazane kumabili akhona. Abesilisa bashaya amaphiko abo kabuhlungu, kepha imvamisa umfokazi angaxoshwa.
Izithandani ngokubambisana zikhetha isayithi eliseduzane nedamu elinogu olugcwele. Kubantu abangashadile, inkathi yokukhwelana iqala ngoMashi. Ngalesi sikhathi, izinyoni ziyabhukuda eduze, ezeduna zishaya amaphiko azo futhi zivame ukucwilisa amakhanda emanzini. Ngemuva kwalokho owesilisa ubhukuda aze afike kowesifazane bese beziphotha izintamo zabo.
Ngemuva kwezenzo ezinjalo, insikazi icwiliswa emanzini kuze kufike entanyeni bese ziyakhwelana. Ngemuva kwalokho lezi zithandani ziyantanta, zibekelele amabele bese ziqala ukuxubha izimpaphe zazo. Ngaphezu kwalokho, insikazi yakha isidleke kude nezindawo lapho abantu bakhona. Eyesilisa ngalesi sikhathi ivikela insimu nokuhoshela nakancane abantu abangabazi.
Lesi sidleke siqukethe umhlanga wangonyaka odlule nezitshalo zasemanzini. Isidleke emanzini angajulile singaba yimitha ubude nobude obungamasentimitha angama-75. Uma yakhiwe ngama-rhizomes, khona-ke ububanzi bayo bungafinyelela kumamitha ayi-4, nokuphakama kwemitha elilodwa. Lapho indawo yokuhlala isilungile, insikazi ikhipha umkhuhlane esifubeni bese igcwala ngezansi ngawo.
AmaSwans anikeza inzalo yawo yokuqala angaba neqanda elilodwa kuphela. Njengoba abesifazane bekhula, inani labo lenyuka laya ku-5-8. Ekuqaleni, amaqanda aseluhlaza okotshani, kepha ngesikhathi kuzalwa iphuphu, iba mhlophe ngombala. Ukufukamela kuthatha cishe izinsuku ezingama-35. Eyesilisa ivikela insimu sonke lesi sikhathi.
Ekuqaleni kwehlobo kuvela amatshwele ampunga, abonayo futhi abhukude nonina kusukela ezalwa. Ezinyangeni ezine zokuqala, izingane zigcwala ngemuva kowesifazane, ebusuku wonke umndeni ulala esidlekeni. Ngezinyanga ezi-5, amaphuphu asuke esezimele. Ekwindla, wonke umndeni undizela ebusika ezindaweni ezifudumele.
