Upholi ogxumayo obheke phambili obomvu

UKUBUKEKA KOPHALI ABAGQUMAYO ESITEZI ESIBOMVU

Lawa ama-parakeet anobude bomzimba obufika ku-27 cm nesisindo esingafika ku-113 amagremu. Umbala oyinhloko wezimpaphe uluhlaza okumnyama, izimpaphe zangaphansi kanye nokundiza emaphikweni ziluhlaza okwesibhakabhaka. Isiphongo, umqhele namachashaza eduze kweqhubu abomvu ngokugqamile. Kuphinde kube nomugqa obomvu esweni ukusuka emlonyeni. Uqhwaku likhulu, lumpunga-luhlaza. Umbala wamehlo unombala osawolintshi kwabesilisa abavuthiwe futhi unsundu kwabesifazane. Izidladla zimpunga. Ayikho i-dimorphism yobulili - bobabili ubulili bunemibala efanayo. Abesifazane ngokuvamile bancane kunabesilisa. Amatshwele abukeka ngendlela efanayo neyabantu abadala, izimpaphe zifiphele ngombala. Emvelweni, i-subspecies engu-6 iyaziwa ukuthi ihluke ngezakhi zombala. Iminyaka yokuphila isuka eminyakeni eyi-10. 

IZINDAWO ZOKUHLALA ZAMAPHOLI ARROZEN ABEZQAMA OKUBOMVU NOKUPHILA ENDALO

Ihlala ezintabeni zaseNew Zealand ukusuka enyakatho kuya eningizimu, eNorfolk Island naseNew Caledonia. Bakhetha amahlathi aminyene, amahlathi agudle ugu, izihlahlana nasemaphethelweni. Lolu hlobo lungaphansi kokuvikelwa futhi luhlukaniswa njengolusengozini. Inani labantu basendle lifinyelela kubantu abangama-53. Izinyoni zihlala emihlambini emincane emiqhele yezihlahla, kodwa zehlela phansi zifuna ukudla. Badabula inhlabathi befuna izimpande nezilimo eziyizigaxa. Zidla nezithelo namajikijolo awile. Ukudla kuhlanganisa nezimbali, izithelo, imbewu, amaqabunga kanye nemiqumbe yezitshalo ezihlukahlukene. Ngaphezu kokudla kwezitshalo, ziphinde zidle izilwane ezincane ezingenamgogodla. Imikhuba yokudla ingase yehluke unyaka wonke kuye ngokutholakala kokudla. Ebusika nasentwasahlobo, ama-parrots adla izimbali. Futhi ehlobo nasekwindla imbewu nezithelo ezengeziwe. 

ISINGENISO

Ngokwemvelo, bakha imibhangqwana eshadile. Kuye ngokuphumelela kokuzalela, izinyoni zingase zinamathelene ngemva kokuzalanisa. Ezinyangeni ezi-2 ngaphambi kwe-oviposition, lo mbhangqwana uchitha isikhathi esiningi ndawonye. Isikhathi sokuzalela siqala phakathi no-Okthoba. Ekuqaleni kuka-Okthoba, eyeduna nensikazi ihlola izindawo ezingase zibe sezidlekeni. Eyeduna ima igadile kuyilapho insikazi ihlola umgodi. Khona-ke, uma indawo ifanelekile, insikazi idlulisela owesilisa uphawu ngokungena nokushiya umgodi izikhathi eziningana. Insikazi ihlomisa isidleke ngokusijulisa sibe ngu-10-15 cm futhi sisenze sibe ngu-15 cm ububanzi. Amapulangwe ahlafunwayo asetshenziswa njengendawo yokulala. Phakathi naso sonke lesi sikhathi, eyeduna ihlala eduze, ivikela indawo kwamanye amaduna, izitholela ukudla yona neyensikazi. Uma ukuzalanisa kube yimpumelelo, amapheya angase asebenzise isidleke esifanayo iminyaka eminingana ilandelana. Ngaphezu kwemigodi yezihlahla, izinyoni zingahlala futhi emifantwini yamadwala, emigodini ephakathi kwezimpande zezihlahla, nasezindaweni zokwenziwa. Iqiniso elithakazelisayo liwukuthi ukuphuma esidlekeni kuvame ukuqondiswa enyakatho. Kusukela ngoNovemba kuya kuJanuwari, izinyoni zizalela amaqanda azo. Usayizi we-clutch ojwayelekile ungamaqanda angama-5-9. Insikazi kuphela ifukamela izinsuku ezingama-23-25, kanti eyeduna iyayifunza futhi iyigade. Amatshwele awazalwa ngesikhathi esisodwa, ngezinye izikhathi umehluko phakathi kwawo izinsuku ezimbalwa. Amatshwele azalwa embozwe nge-sparse fluff. Ezinsukwini ezimbalwa zokuqala, insikazi iphakela amatshwele ngobisi lwe-goiter. Ngokuvamile ngosuku lwe-9 lokuphila, amatshwele avula amehlo awo, ngaleso sikhathi iduna livunyelwe ukungena esidlekeni. Lapho eneminyaka engama-5 - 6 amasonto, amatshwele anezimpaphe aqala ukushiya isidleke. Abazali bazondla amasonto ambalwa ngaphezulu.
