Cape shirokosnoska (Anas smithii) kapena Smith's bakha ndi woimira banja la bakha, ma anseriformes order.
Zizindikiro zakunja kwa Cape shirokonoski.
Cape shirokonoska ili ndi kukula: masentimita 53. Kulemera kwake: 688 - 830 magalamu. Nthenga za mkazi ndi zazikazi, monga abakha ambiri akumwera, ndizofanana. Mwaimuna yayikulu, mutu ndi khosi ndizimvi zachikaso ndi mikwingwirima yaying'ono yakuda, yomwe imawonekera kwambiri pamutu ndi kumbuyo kwa mutu. Nthenga za thupi zimakhala pafupifupi zofiirira kwathunthu, koma nthenga zimakhala ndi bulauni zachikasu m'mbali, zomwe zimapangitsa mtunduwo kukhala mthunzi wachilendo. Nsagwada ndi nthenga za mchira zimakhala zobiriwira zobiriwira mosiyana pang'ono ndi nthenga zonse zakuda za mchira. Nthenga zapamwamba zokhala ndi buluu wonyezimira, nthenga zophimba kuphiko ndi imvi buluu.
Kukongoletsa koyera kumakongoletsa nthenga zazikulu zazikuluzikulu. Zonse zoyambirira ndi zofiirira, zachiwiri - zobiriwira buluu ndizitsulo zazitsulo. Amawoneka bwino akuthawa, mapiko a mbalamezo atatumizidwa. Manja oyera ndi utoto, okhala ndi mawanga abulauni m'malire. Nthenga za mchira ndizofiirira. Cape shirokosnoska ili ndi mlomo waukulu wa spatulate. Miyendo ya utoto wonyezimira wa lalanje. Monga abakha ambiri akumwera, amuna ndi akazi ndi ofanana, koma wamwamuna ndi wopepuka kuposa wamkazi. Ali ndi galasi lobiriwira lomwe lili ndi malire oyera ndi maso achikaso. Zowonetseratu zazimayi ndizimvi, nthenga zake ndizosalala komanso zochepa kusiyanasiyana, koma kuwunikira kwamtundu wa nthenga ndikotakata. Mutu ndi khosi zimasiyana pang'ono ndi thupi lonse.
Dera lamapewa amapewa, chotupa ndi nthenga zina za mchira ndizofiirira. Mphepete mwa nthenga zazikuluzikulu ndizocheperako komanso imvi, motero sizowoneka.
Mbalame zazing'ono zimafanana ndi zazikazi, koma nthenga zawo zimakhala ndi mawonekedwe owoneka bwino. Amuna achimuna amasiyana ndi akazi achichepere pamtundu wamapiko awo.
Mverani mawu aku Cape Shirokonoski.
Liwu la mitundu ya bakha Anas smithii limveka motere:
Malo a Cape Shirokonoski.
Cape shirokonoski imakonda malo osaya komanso amchere monga nyanja, madambo ndi madzi osakhalitsa. Mbalame sizikhazikika m'madzi akuya, mitsinje yothamanga kwambiri, malo osungira madzi ndi madamu, koma zimangoyima pang'ono kuti zipezeko pogona. Cape shirokoski imadyetsa m'madamu okhala ndi malo opangira chithandizo, pomwe zamoyo zambiri zam'madzi zimayendera, amapitanso kunyanja zamchere (pH 10), mafunde am'madzi, nyanja zamchere, madambo ndi madambo amchere. Amapewa mayiwe okhala ndi madamu ang'onoang'ono, komwe amapeza madzi othirira ulimi. Malo oterewa amagwiritsidwa ntchito ngati pogona kwakanthawi.
Kufalitsa kwa Cape Shirokonoski.
Cape shirokoski imagawidwa kumwera chakumwera kwa Africa. Malo awo okhala pafupifupi South Africa yonse ndikupitilira kumpoto, kuphatikiza Namibia ndi Botswana. Anthu ena ochepa amakhala ku Angola ndi Zimbabwe. Ku South Africa, abakha amtunduwu amapezeka kwambiri ku Cape ndi Transvaal, samapezeka ku Natal. Cape Shirokoski ndi mbalame zokhazikika, koma zimatha kuyendayenda komanso kufalikira kudera la South Africa. Paulendo wapaulendo wanyengo, Cape Shirokoski imawonekera ku Namibia, yomwe imayenda pafupifupi 1650 km. Kusunthaku sikumveka bwino, chifukwa kusamuka kumachitika pakati pa dzinja ndi nthawi yotentha. Kupezeka kwa mbalame m'malo amenewa kumadalira kupezeka kwa madzi komanso kupezeka kwa chakudya.
Makhalidwe a Cape Shirokonoski.
Cape Shirokoski nthawi zambiri ndimabakha ochezeka. Amapanga awiriawiri kapena ang'onoang'ono a mbalame, koma pakasungunuka amasonkhana m'magulu a anthu mazana angapo.
Mu mbalame zazikulu, nyengo ya molt imatha masiku 30; panthawiyi samauluka ndikukhala m'madzi akuluakulu otseguka okhala ndi plankton. Amadyetsa usana ndi usiku.
Pakudyetsa, Cape shirokonoski imakhala ngati onse m'banja la bakha. Amathamanga ndikusambira, akukankhira pamwamba pamadzi ndi milomo yawo, nthawi zina akumiza mutu ndi khosi, samapindika kawirikawiri. Ngakhale m'madzi akulu, Cape Shirokoski nthawi zina imaphatikizana ndi mitundu ina ya anatidae, komabe, amakhala kutali pagulu lawo.
Bakha amawuluka mofulumira. Kuchokera pamwamba pamadzi, amatuluka mosavuta mothandizidwa ndi mapiko amipiko. Kusamuka kwawo kwakanthawi sikudziwika bwino, mwina chifukwa chokhazikitsa nyengo yadzuwa. Komabe, Cape Shirokoski imatha kuwuluka mtunda wopitilira makilomita 1000.
Kubereka kwa Cape Shirokonoski.
M'madera ake ambiri, Cape Shirokoski imaberekanso chaka chonse. M'malo ena, kuswana kumakhala nyengo yake. Nsonga yayikulu kumwera chakumadzulo kwa Cape imayamba kuyambira Ogasiti mpaka Disembala.
Mitengo imapangidwa pambuyo pa kusungunuka. Angapo awiriawiri a abakha chisa m'dera lawo.
Cape shirokonoski imakonda kukhala pachisa m'madzi osazama kwambiri okhala ndi zamoyo zopanda mafinya. Chisa chimakonzedwa mu dzenje losaya pamtunda, nthawi zambiri chimapanga ma bumpers ndi denga la zomera. Ili pafupi ndi madzi. Zipangizo zazikulu zomangira ndi mapesi a bango ndi udzu wouma. Kapangidwe kamapangidwa ndi pansi. Chowotcheracho chimakhala ndi mazira 5 mpaka 12, omwe mkazi amawasirira masiku 27 mpaka 28. Anapiye amawoneka, ataphimbidwa pamwamba ndi bulauni wonyezimira, m'munsimu - wotumbululuka wachikasu. Amakhala odziyimira pawokha pakatha masabata pafupifupi 8 ndipo amatha kuwuluka.
Chakudya cha Cape Shirokonoski.
Mitundu ya bakha ndi yamphongo. Chakudyacho chimayang'aniridwa ndi nyama. Cape shirokoski imadyetsa makamaka zazing'onozing'ono zopanda tizilombo: tizilombo, molluscs ndi crustaceans. Amadyanso amphibians (achule tadpoles a genus Xenopus). Zimayamwa zakudya zamasamba, kuphatikizapo mbewu ndi zimayambira za m'madzi. Cape shirokoski imapeza chakudya poyenda m'madzi. Nthawi zina amadyetsa limodzi ndi abakha ena, akukweza matope kuchokera pansi pa dziwe, momwe amapezamo chakudya.
Malo osungira Cape Shirokonoski.
Cape shirokonoski ndi mtundu wofala kwambiri kwanuko. Palibe kuyerekezera kwa kuchuluka kwawo komwe kudachitikapo, koma zikuwoneka kuti, mtundu wa zamoyozi ndiwokhazikika poti palibe chiwopsezo chenicheni pamalo ake. Choopseza chokha ku Cape Shirokos ndikuchepa kwa malo okhala mafunde omwe akupitilira ku South Africa. Kuphatikiza apo, abakha amtunduwu amatha kusakanikirana ndi mitundu yovuta, mallard (anas platyrhynchos). Monga abakha onse, Cape Shirokoski imatha kugwidwa ndi avian botulism, chifukwa chake akhoza kukhala pachiwopsezo ngati matendawa afalikira pakati pa mbalame.
Malinga ndi mfundo zazikuluzikulu, Cape Shirokoski amadziwika kuti ndi mbalame zomwe zimaopseza kwambiri komanso anthu ochepa.
