Inkukhu ihansi (Cereopsis novaehollandiae) ingeyomndeni wedada, i-oda le-Anseriformes.
Abaphenyi baseYurophu babona ihansi lezinkukhu esiQhingini saseCape esasingenamuntu. Leli ihansi elimangalisayo elinokubukeka okwehlukile. Kubukeka njengehansi langempela, i-swan ne-sheath ngasikhathi sinye. Izinsalela zamahansi angakwazi ukundiza ohlobo lweCnemiornis, umndeni ohlukile waseCereopsinae, zitholakale esiqhingini saseNew Zealand. Ngokusobala, lawa kwakungokhokho behansi lanamuhla lezinkukhu. Ngakho-ke, lolu hlobo ekuqaleni lwalubizwa ngephutha ngokuthi “New Zealand - Cape Barren goose” (“Cereopsis” novaezeelandiae). Iphutha labe selilungiswa futhi inani lamahansi eCape Barren eNtshonalanga Australia lachazwa njengama-subspecies, iCereopsis novaehollandiae grisea B, eqanjwe ngeqembu leziqhingi ezibizwa ngegama elifanayo njengeziqhingi zaseRecherche.
Izimpawu zangaphandle zehansi lenkukhu
Ihansi lenkukhu linosayizi womzimba ongaba ngu-100 cm.
Ihansi lenkukhu linezimpaphe eziluhlaza ezimpunga ezinombala omnyama onomaka omnyama eduze kwamathiphu ezimpaphe zephiko nomsila. Kuphela ikepisi elisekhanda enkabeni lilula, licishe libe mhlophe. Ihhuku lezinkukhu liyinyoni enkulu futhi enesisindo enesisindo esisuka ku-3.18 - 5.0 kg. Ayikwazi ukudideka nganoma iyiphi enye inyoni etholakala eNingizimu ye-Australia ngenxa yomzimba wayo omkhulu ojwayelekile namaphiko abanzi kakhulu. Ukumboza izimpaphe zephiko ngemivimbo emnyama. Imiphetho yezimpaphe zesibili, eziyinhloko kanye nomsila kumnyama.
Uqhwaku lumfushane, lumnyama, ucishe ufihlwe ngokuphelele ngomlomo wethoni ekhanyayo ephuzi ngokuluhlaza.
Imilenze ebomvu umbala omnyama, mnyama ngaphansi. Izingxenye zetars nezinzwane zimnyama. Iris ibomvu ngokubomvu. Zonke izinyoni ezincane zifana ngombala wezimpaphe kubantu abadala, noma kunjalo, izindawo ezisezimpikweni zigqama ngokusobala. Ithoni yezimpaphe ilula futhi ayifiphele. Imilenze nezinyawo ziluhlaza noma zimnyama ekuqaleni, bese zithola umthunzi ofanayo nowezinyoni ezindala. I-iris yehluke kancane futhi inombala onsundu ngokukhanyayo.
Inkukhu ihansi isakazeka
Ihansi lenkukhu liyinyoni enkulu edabuka eningizimu ye-Australia. Lezi zinhlobo zivame kakhulu ezwenikazi i-Australia, lapho zakha khona izindawo ezine ezinkulu zokwakha izidleke. Phakathi nawo wonke unyaka, bathuthela eziqhingini ezinkulu nasemaphakathi nezwe. Ukufuduka okunjalo kwenziwa ikakhulukazi ngamahansi amancane ezinkukhu, angahlali. Izinyoni ezindala zikhetha ukuhlala ezindaweni ezizalela kuzo.
Ukuhamba ibanga elide ogwini oluseningizimu ye-Australia kuya eziqhingini zaseRechsch eNtshonalanga Australia, isiQhingi saseKangaroo naseSir Joseph Banks Island, iziQhingi Zogu lolwandle iVictorian ezungeze iWilsons Promontory Park, kanye neBass Strait Islands kubandakanya iHogan, Kent, Curtis kanye neFurneaux. Inani elincane lamahansi ezinkukhu litholakala eCape Portland eTasmania. Ezinye izinyoni ziye zaziswa eMary Island, eziqhingini ezisogwini oluseningizimu-mpumalanga nasenyakatho-ntshonalanga yeTasmania.
Indawo yokuhlala ihansi lenkukhu
Izinkukhu zamahansi zikhetha izindawo osebeni lomfula ngenkathi yokuzalanisa, zihlala emadlelweni eziqhingi ezincane bese zondla ngasogwini. Ngemuva kokufaka izidleke, bahlala emadlelweni nasemachibini asogwini ngamanzi ahlanzekile noma abilayo ezindaweni ezivulekile. Esikhathini esiningi, amahansi ezinkukhu ahlala kakhulu eziqhingini ezisogwini ezincane, ezinomoya nezingenamuntu, kepha basengozini yokuvela ezindaweni eziseduzane nezolimo bezofuna ukudla ehlobo. Ikhono labo lokuphuza amanzi anosawoti noma awosawoti livumela amanani amaningi amahansi ukuba ahlale eziqhingini ezingaphandle unyaka wonke.
Izici zokuziphatha kwehansi lenkukhu
Amahansi ezinkukhu ayizinyoni ezinobungane, kepha imvamisa zihlala emihlanjini emincane kuyaqabukela zifinyelele kuzinyoni ezingama-300. Atholakala eduze nolwandle, kepha kuyaqabukela abhukude futhi awangeni njalo emanzini, noma ngabe asengozini. Njengamanye ama-anatidae amaningi, amahansi ezinkukhu alahlekelwa amandla okundiza ngesikhathi sokuncibilika lapho izimpaphe zephiko nomsila ziwa. Lolu hlobo lwamahansi, uma kwenzeka lusongela impilo, luphakamisa umsindo omkhulu owethusa izilwane ezidla ezinye. Indiza yamahansi yenkukhu indiza enamandla, equkethe amaphiko asheshayo amaphiko, kepha kunzima kancane. Zivame ukundiza njengemihlambi.
Ukuzalela ihansi lenkukhu
Isikhathi sokuzalela amahansi enkukhu side impela futhi siqala ngo-Ephreli kuya kuSepthemba. Amabili ahlala njalo akhiwa. Ogcina ubuhlobo impilo yonke. Izinyoni zakha isidleke emfuleni ekoloni futhi zisatshalaliswa ngokulinganayo, zivikela ngenkuthalo indawo ekhethiwe. Umbhangqwana ngamunye unquma indawo yawo ekwindla, ulungisa isidleke futhi uxoshe futhi ngokuthula amanye amahansi kuwo. Izidleke zakhiwa phansi noma ngaphezulu, kwesinye isikhathi ezihlahleni nasezihlahleni ezincane.
Amahansi abekela amaqanda awo ezidlekeni ezitholakala kuma-hummock ezindaweni ezivulekile zedlelo ahlala kulo.
Kukhona cishe amaqanda amahlanu ku-clutch. Ukufukamela kuthatha cishe inyanga. Izikhukhukazi zikhula futhi zikhule ngokushesha phakathi nobusika, kuthi kuphela intwasahlobo zikwazi ukundiza. Ukondla amaphuphu kuthatha cishe izinsuku ezingama-75. Amahansi amancane abese egcwalisa imihlambi yamahansi angenazidleke nawo asebenzise ubusika esiqhingini lapho izinyoni zizalela khona.
Ekuqaleni kwehlobo, insimu yesiqhingi iyoma, ikhava yotshani iphenduka ibe phuzi futhi ingakhuli. Yize kusekhona ukudla okwanele kwezinyoni okungasinda ehlobo, amahansi ezikhukhukazi avame ukushiya lezi ziqhingi ezincane bese ethuthela eziqhingini ezinkulu eziseduze nezwekazi, lapho izinyoni zidla khona emadlelweni acebile. Lapho kuqala imvula yasekwindla, imihlambi yamahansi ezinkukhu ibuyela eziqhingini zayo ukuze izale.
Inkukhu ihansi umsoco
Izinkukhu zamahansi ezinkukhu emzimbeni wamanzi. Lezi zinyoni zinamathela kuphela ekudleni kwemifino futhi zondla emadlelweni. Izinkukhu zezinkukhu zichitha isikhathi esiningi ezimfundeni kangangokuba endaweni, zibangela izinkinga ezithile kubalimi bemfuyo futhi zibhekwa njengezilokazane zezolimo. La mahansi aklaba ikakhulukazi eziqhingini ezinama-hummock ezimbozwe ngotshani obuhlukahlukene neziphuzo ezinoshukela. Badla ibhali ne-clover emadlelweni.
Isimo sokongiwa kwehansi yenkukhu
Ihansi lezinkukhu alihlangabezani nezinsongo ezithile ezinombolweni zalo. Ngenxa yalezi zizathu, lolu hlobo akuyona inyoni engandile. Kodwa-ke, endaweni yokuhlala izinhlobo zezikhukhukazi kwakukhona isikhathi lapho inani lezinyoni lehla kakhulu kangangoba ososayensi bezinto eziphilayo besaba ukuthi amahansi ayesezophela nya. Izinyathelo ezithathiwe ukuvikela nokwandisa isibalo zinikeze imiphumela emihle futhi zaletha inani lezinyoni ezingeni eliphephile ukuba khona kwalezi zinhlobo. Ngakho-ke, ihansi lezinkukhu lasinda engozini yokuqothulwa. Noma kunjalo, lolu hlobo luhlala lungomunye wamahansi ayivelakancane emhlabeni, angasakazeki kakhulu.
