Zizindikiro zakunja kwa bakha waku Australia
Bakha waku Australia amakhala ndi thupi lokulira pafupifupi 40 cm, mapiko ake ndi masentimita 60. Kulemera kwake: kuyambira 850 mpaka 1300 g.
Ku Australia, mitunduyi imangosokonezedwa ndi bakha wokhala ndi mphalapala (Biziura lobata), komabe bakha wa ku Australia ndi wocheperako pang'ono ndipo amakhala ndi mchira wowongoka.
Mutu wamphongo wokutidwa ndi nthenga zakuda za jet zomwe zimasiyanitsa ndi nthenga za bulauni za thupi. Pansi pake pa chifuwa ndi pamimba ndizotuwa. Chochitikacho ndi choyera - silvery. Mapikowo ndi ofiira komanso alibe kalilole. Manja oyera ndi oyera. Mlomo ndi wabuluu, ndiye mawonekedwe ake. Mawondo ndi miyendo ndi imvi. Iris ya diso ndi yofiirira. Mwakhama, Bakha wa ku Australia amadziwika ndi nthenga zake zochuluka.
Mkaziyo amasiyana ndi akazi ena amtundu wa Oxyura mumakina otetezedwa kwambiri a nthenga. Nthenga m'thupi ndizimvi, ndizikwapu zingapo, kupatula gawo lakumunsi. Mlomo ndi beige. Mbalame zazing'ono ndizofanana ndi zazikazi mumtundu wa maula, koma zimakhala ndi milomo yobiriwira yakuda, yomwe imathera ndi mbedza. Amuna achimuna amakhala ndi mbalame zazikulu ali ndi zaka 6 ndi 10.
Habitat Ya Australia
Bakha Woyera wa ku Australia amapezeka m'matope a madzi oyera ndi m'madzi osaya. Amakonda nyanja ndi madambo, m'mphepete mwa magombe omwe muli nkhalango zowirira zazitali.
Kunja kwanyengo, abakha amtunduwu amathanso kupezeka munyanja zazikulu komanso mosungira madzi okhala ndi zonyansa, m'madziwe ndi ngalande zazikulu. Ngakhale kuti nthawi zina bakha wa mitu yoyera waku Australia amayendera madera a m'mphepete mwa nyanja ndi madzi amchere, samapezeka kawirikawiri m'malo owonera nyanja.
Makhalidwe a bakha waku Australia
Atapanga mazira, Bakha wamutu woyera waku Australia amasonkhana m'magulu akulu. M'nyengo yobereketsa, amakhala okhaokha ndi kubisala m'nkhalango kuti asadziwike.
Yaimuna imateteza malo okhala ndi zokoka ndipo imakopa yaikazi kuti ikwere.
Bakha wa ku Australia ndiwodabwitsa chifukwa chothamanga. Bakha nthawi zina amatha kukwera zitsa za mitengo, koma nthawi zambiri amathera pamadzi. Abakhawa nthawi zambiri amalumphira limodzi ndi matanga.
Pothawa, Bakha wa ku Australia amadziwika mosavuta ndi mawonekedwe ake osiyana. Mbalame ndizocheperako kukula kwamthupi kuposa ma enceism ena. Bakha wa ku Australia ndi mbalame yakachetechete, yosachita zachilengedwe mwaphokoso.
Komabe, m'nyengo yokhwima, amuna amapanga phokoso ndi michira yawo ndi mawoko akuthira m'madzi. Kusunthika koteroko nthawi zina kumamveka madzulo komanso usiku pamtunda wopitilira 1 mita kapena kupitilira apo, kutengera nyengo. Amuna amapanganso kumveka, kutulutsa madzi mwaphokoso m'milomo yawo atasambira. Akazi nthawi zambiri amakhala chete, kupatula pamene ana a bakha amatchedwa.
Makhalidwe azakudya za bakha waku Australia
- Bakha wa ku Australia amadyetsa mbewu, mbali zina za zomera zam'madzi.
- Amadyanso tizilombo tomwe timakhala paudzu m'mbali mwa nyanja ndi mayiwe.
- Chironomidés, ntchentche za caddis, agulugufe ndi kafadala amadyedwa, omwe amapanga zakudya zambiri.
- Menyu imakwaniritsidwa ndi ma molluscs, crustaceans ndi arachnids.
Kuswana ndi kumanga zisa za bakha waku Australia
Nthawi ya nyengo yoswana imasiyanasiyana malinga ndi dera.
Abakha oyera ku Australia amayamba kupanga zisa zawo pakagwa mkhalidwe wabwino. Mwambiri, mbalame zimaswana m'miyezi yonse yachaka, koma zimakonda miyezi yachisanu kumwera chakum'mwera ndi koyambirira kwa chilimwe.
Bakha waku Australia ndi mbalame zamitala. Amapanga awiriawiri pakanthawi kokhwimitsa komanso asanabadwe. Ziwombankhanga zimatha, choncho mbalame zimakhala ndi ana amodzi pa nyengo.
Abakha amakonda kupanga chisa paokha; amamanga chisa chozama choboola mpira chokhala ndi dome kuchokera masamba owuma. Pansi pa chisa nthawi zina chimakhazikika pansi. Ili mu zomera zowirira pafupi ndi madzi, m'mphepete mwa nyanja kapena pachilumba chaching'ono mkati mwa nyanjayi. Mu clutch, monga lamulo, pali mazira 5 kapena 6 a mazira obiriwira, omwe amalemera pafupifupi magalamu 80. Amayi okhaokha amakwanira masiku 24 - 27. Anapiye amaswa ndikulemera pafupifupi magalamu 48. Amakhalabe pachisa kwa milungu 8.
Ndi akazi okha omwe amatsogolera ankhandwe.
Amateteza ana mwamphamvu makamaka masiku khumi ndi awiri oyambirira. Anapiye amadziyimira patadutsa miyezi iwiri. Abakha achichepere amaswana chaka chamawa. Bakha wa ku Australia ndi mbalame yakachetechete, yosachita zachilengedwe mwaphokoso.
Mkhalidwe Wosunga Bakha wa ku Australia
Bakha ndi mtundu wocheperako ndipo chifukwa chake amadziwika kuti ali pachiwopsezo. Mwina ngakhale kuchuluka kwa mbalame ndi kochepera kuposa momwe akuganizira pano. Ngati anthu apezeka kuti ndi ochepa kwambiri ndipo akuchepa, Bakha wa Australia adzawerengedwa kuti akuwopsezedwa. Komabe, m'maiko ena aku Australia: Victoria ndi New South Wales, mtundu uwu uli pachiwopsezo ndipo uli pachiwopsezo.
Kuwerengetsa kosiyanasiyana komwe kumachitika kumadera ena akumwera chakumadzulo kwa kontrakitala kumawonetsa kuti abakhawa amapewa kukhazikika m'malo omwe ngalande zake zimayikidwako kapena komwe kumasintha madambo. Kuphatikiza apo, alenje akupitilizabe kuona mtundu wa abakha ngati chinthu chosangalatsa pakusaka masewera ndikuwombera mbalame ngati masewera.
Chilala chomwe chimachitika pafupipafupi m'malo ena a kontrakitala chimabweretsa kuchepa kwa bakha wa mutu woyera ku Australia. Malo okhala bakha akuchepa chifukwa cha ngalande zamadambo akuya kapena kuwonongeka kwawo chifukwa chakukhazikika kwa mitundu ya nsomba zomwe zatumizidwa kunja, msipu wamphepete, mchere ndi kuchepa kwamadzi apansi panthaka. Chodetsa nkhaŵa kwambiri ndi momwe chiwerengero cha anthu chakumadzulo kwa dera lino chilili, chifukwa cha kuyembekeza kosasintha kwa nyengo mdera lino. Mvula imachepa chifukwa kutentha kumakwera, motero kuchepa kwa madambo.
Palibe njira zomwe zatetezedwa zomwe zakonzedwa kuti zisunge bakha wamutu woyera waku Australia. Kuzindikira madambo osatha omwe amagwiritsidwa ntchito pobzala ndi kusungunula bakha wamutu woyera waku Australia ndikuwateteza ku kuwonongeka kwina kudzatithandiza kupewa kuchepa kwambiri. Kuphatikiza apo, ndikofunikira kuwunika momwe kuchuluka kwa anthu zikuyendera kudzera pamafukufuku wamba.
