ICape shirokosnoska (Anas smithii) noma idada likaSmith limele umndeni wedada, i-anseriformes oda.

Izimpawu zangaphandle zeCape shirokonoski.

ICape shirokonoska inosayizi: amasentimitha angama-53. Isisindo: 688 - 830 amagremu. Izimpaphe zabesilisa nabesifazane, njengamadada amaningi aseningizimu, cishe ziyefana. Kowesilisa osekhulile, ikhanda nentamo kunombala ophuzi-mpunga ngemivimbo emincanyana emnyama, ebonakalayo kakhulu esigqokweni nasemuva kwekhanda. Izimpaphe zomzimba zicishe zibe nsundu ngokuphelele, kepha izimpaphe zinemiphetho ebanzi ephuzi ngoku nsundu, okunikeza umbala umthunzi okhethekile. Izimpaphe zesinqe nezomsila zinombala oluhlaza okotshani ngokungafani nokuncane kwezinye izimpaphe ezimnyama zomsila. Izimpaphe zemfundo ephakeme ezinombala oluhlaza okwesibhakabhaka, izimpaphe zokumboza zephiko zinombala oluhlaza okwesibhakabhaka.

Ukuhlelwa okumhlophe okubanzi kuhlobisa izimpaphe ezinkulu ezinkulu. Konke okuyinhloko kunsundu onsundu, okwesibili - okuluhlaza okwesibhakabhaka noluhlaza okotshani okusansimbi. Zibonakala ngokusobala lapho zindiza, lapho amaphiko ezinyoni efakwa. Izindwangu zangaphansi zimhlophe qwa, zinamabala ansundu emingceleni. Izimpaphe zomsila zinsundu ngokumpunga. ICape shirokosnoska inomlomo omkhulu we-spatulate. Imilenze yombala onsundu wewolintshi. Njengamadada amaningi aseningizimu, ubulili buyafana, kepha owesilisa upholile kunowesifazane. Banesibuko esiluhlaza esinomngcele omhlophe namehlo aphuzi. Izibikezelo zesifazane zimpunga, izimpaphe zithambile futhi azishintshashintshi, kepha ukukhanyiselwa kombala wezimpaphe kubanzi. Inhloko nentamo ziqhathanisa kancane nawo wonke umzimba.

Indawo yamahlombe, isigaxa nezinye izimpaphe zomsila zinsundu ngokukhanyayo. Amaphethelo ezimpaphe ezinkulu ezisemaceleni anciphile futhi anombala ompunga, ngakho-ke cishe akabonakali.

Izinyoni ezisencane ziyefana nezinsikazi, kepha izimpaphe zazo zinephethini elithuthukile le-scaly. Izinsizwa ezisencane zehlukile kwabesifazane abasebancane ngombala wamaphiko abo.

Izwi lohlobo lwedada u-Anas smithii lizwakala kanjena:

Izindawo zokuhlala eCape Shirokonoski.

ICape shirokonoski ithanda izindawo ezijulile nezintsha ezinamachibi njengamachibi, amaxhaphozi namanzi esikhashana. Izinyoni azihlali emachibini ajulile, emifuleni enomsinga osheshayo, amadamu namadamu, kepha zime kuphela kuwo okwesikhashana ukuze zikhosele. I-Cape shirokoski idla emithonjeni enezindawo zokwelashwa, lapho kukhula khona izinto eziningi zeplanktonic, zivakashela namachibi ane-alkaline (pH 10), iziziba zamaza, amachibi anosawoti, amachibi kanye namachibi kasawoti. Bagwema amachibi anamadamu amancane, lapho bethola khona amanzi okunisela lawo ezolimo. Izindawo ezinjalo zamadada zisetshenziswa njengezindawo zokukhosela zesikhashana.

Ukusatshalaliswa kweCape Shirokonoski.

I-Cape shirokoski isatshalaliswa engxenyeni eseningizimu yezwekazi lase-Afrika. Indawo abahlala kuyo ihlanganisa cishe yonke iNingizimu Afrika futhi iqhubekela ngasenyakatho, kubandakanya iNamibia neBotswana. Abanye abantu abancane bahlala e-Angola naseZimbabwe. ENingizimu Afrika, lolu hlobo lwamadada lusakazeke kakhulu eKapa naseTransvaal, alutholakali kakhulu eNatali. ICape Shirokoski iningi lezinyoni ezihlala phansi, kepha zingenza iminyakazo yokufuduka nokuhlakazeka kuyo yonke indawo yeNingizimu Afrika. Ngesikhathi sezindiza zonyaka, iCape Shirokoski ivela eNamibia, ebanga ibanga elifinyelela ku-1650 km. Lokhu kuhamba akucaci ngokuphelele, njengoba ukufuduka kwenzeka phakathi kobusika nehlobo. Ukuba khona kwezinyoni kulezi zindawo kuncike ekutholakaleni kwamanzi nasekutholakaleni kokudla.

Izici zokuziphatha kweCape Shirokonoski.

ICape Shirokoski imvamisa iba ngamadada athanda ubudlelwano. Bakha ngazimbili noma ngamaqembu amancane ezinyoni, kepha ngesikhathi se-molting bahlangana emihlambini yabantu abangamakhulu amaningana.

Ezinyonini ezindala, isikhathi se-molt sihlala izinsuku ezingama-30; ngalesi sikhathi azindiza futhi zihlala emanzini amakhulu avulekile acebile eplankton. Zondla imini nobusuku.

Ngesikhathi sokudla, iCape shirokonoski iziphatha njengawo wonke amalungu omndeni wedada. Ziyafafaza futhi zibhukude, zicindezele ingaphezulu lamanzi ezinhlangothini ngomlomo wazo, kwesinye isikhathi zicwilisa ikhanda nentamo, kuyaqabukela zigobe. Yize isemizimbeni emikhulu yamanzi, iCape Shirokoski kwesinye isikhathi ihlangana nezinye izinhlobo ze-anatidae, noma kunjalo, zihlala kude eqenjini lazo.

Amadada andiza ngokushesha. Ukusuka ebusweni bamanzi, zikhuphuka kalula ngosizo lwama-wing flaps. Ukufuduka kwabo ngezikhathi ezithile zonyaka akwaziwa, mhlawumbe kuhlobene nokusungulwa kwenkathi eyomile. Kodwa-ke, iCape Shirokoski iyakwazi ukundiza ngaphezu kwamakhilomitha ayi-1000.

Ukukhiqizwa kabusha kweCape Shirokonoski.

Kububanzi bayo obukhulu, iCape Shirokoski izala unyaka wonke. Kwezinye izindawo, ukuzalanisa kunesikhathi sonyaka esithile. Inani eliphakeme lokudlela eningizimu-ntshonalanga yeKapa liqala ngo-Agasti kuya kuDisemba.

Ama-vapor akhiwa ngemuva kokuncibilika. Amabhangqa amaningana amadada esidlekeni endaweni.

ICape shirokonoski ithanda ukwakha isidleke emizimbeni yamanzi evundile engajulile enezinambuzane ezingenamgogodla. Isidleke sihlelwe emgodini ongajulile emhlabeni, imvamisa sakha izinhlangothi nombhede wohlaza. Itholakala eduze kwamanzi. Izinto zokwakha eziyinhloko izingongolo zomhlanga notshani obomile. Ulwelwesi lwakhiwa phansi. I-clutch iqukethe amaqanda ayisi-5 kuya kwayi-12, insikazi efukama izinsuku ezingama-27 kuye kwangama-28. Kuvela amachwane, embozwe phezulu nge-brown fluff, ngezansi - i-yellow fluff. Zizimela ngokuphelele ngemuva kwamasonto angaba ngu-8 futhi ziyakwazi ukundiza.

Ukudla okunomsoco kweCape Shirokonoski.

Lolu hlobo lwamadada ludla omnivorous. Ukudla kubuswa yizilwane. I-Cape shirokonoski idla kakhulu ezinambuzaneni ezincane: izinambuzane, ama-molluscs nama-crustaceans. Baphinde badle izilwane eziphila ezweni nasemanzini (onoshobishobi bamaxoxo bohlobo lweXenopus). Kumunca ukudla kwezitshalo, kufaka phakathi imbewu neziqu zezitshalo zasemanzini. ICape Shirokoski ithola ukudla ngokuzulazula emanzini. Kwesinye isikhathi zidla ndawonye namanye amadada, zikhulisa inqwaba yodaka kusuka phansi echibini, lapho bethola khona ukudla.

Isimo sokongiwa kweCape Shirokonoski.

ICape shirokonoski iyinhlobo esakazeke kakhulu endaweni. Akukho kuhlolwa kwamanani abo okwake kwenziwa, kepha ngokusobala, isimo sezinhlobo zezinto eziphilayo sizinzile impela uma kungekho zinsongo zangempela endaweni yaso. Okuwukuphela kosongo kwiCape Shirokos ukwehla kwendawo enamanzi okuqhubeka eNingizimu Afrika. Ngaphezu kwalokho, lolu hlobo lwamadada lusengozini yokuxubaniswa nezinhlobo ezihlaselayo, i-mallard (anas platyrhynchos). Njengawo wonke amadada, iCape Shirokoski isengozini yokuqubuka kwe-avian botulism, ngakho-ke zingaba sengozini uma lesi sifo sisakazeka phakathi kwezinyoni.

Ngokwezinqubo eziyinhloko, iCape Shirokoski ihlukaniswa njengezinyoni ezinezinsongo ezincane kanye nenani labantu elizinzile.
