Bakha wokhala ndi lobed (Biziura lobata) ndi wa banja la bakha, dongosolo la Anseriformes.
Zizindikiro zakunja kwa bakha wokhala ndi lobed
Bakha wa Lobe amakhala ndi kutalika kwa masentimita 55 mpaka 66. Kulemera kwake: 1.8 - 3.1 kg.
Bakha wokhala ndi mphalapala ndi bakha wosiyanasiyana wosiyanasiyana, wokhala ndi thupi lalikulu komanso mapiko amfupi, zomwe zimapangitsa mawonekedwe ake kukhala osiyana kwambiri. Bakha ameneyu ndi wamkulu ndipo nthawi zambiri amayandama pamadzi. Zimauluka monyinyirika ndipo sizimawoneka kawirikawiri pamtunda.
Nthenga zamphongo ndizofiirira-zakuda, zokhala ndi kolala yakuda komanso hood. Nthenga zonse zokutira kumbuyo ndi mbali zonse zimakhala ndi ma suede ndi ma vermiculées oyera. Chifuwa ndi mimba ndizofiirira. Nthenga za mchira ndizakuda. Mapikowo ndi ofiira-opanda bulauni. Ma underwings ndi ofiira kwambiri. Anthu ena amatuluka nsonga za mapiko awo. Mlomo ndi wawukulu komanso wokulirapo m'munsi mwake, pomwe pamakhala kukula kokulirapo. Ndikukula komwe kumafanana ndi caroncule, kukula kwake kumasiyanasiyana ndi msinkhu wa mbalameyo. Nkhono ndi imvi mdima, miyendo kwambiri. Iris ndi bulauni yakuda.
Mwa mkazi, kakulidwe kamlomo ndi kakang'ono komanso kowonekera kuposa kaimuna. Nthengawo ndi yotumbululuka, chifukwa chakumveka kwa nthenga. Mbalame zazing'ono zimakhala ndi mtundu wa maula, monga mwa akazi akuluakulu. Koma gawo lotsirizira la mandible m'munsi ndilochepa komanso lachikasu.
Malo okhala bakha wa Lobe
Abakha okhala ndi loboti amakonda madambo ndi nyanja zokhala ndi madzi abwino, makamaka ngati gombe lawo ladzaza ndi bango lokwanira. Mbalame zimathanso kuwonedwa munthambi zowumitsa mitsinje komanso m'mphepete mwa madamu osiyanasiyana, kuphatikiza ofunika chuma.
Kunja kwa nyengo yakuberekera, abakha achikulire ndi achichepere amasonkhana m'madzi ozama kwambiri monga nyanja zamchere, madamu, ndi mayiwe amadzimadzi. Munthawi ino ya chaka, amapitanso kumalo osungira madzi othirira, mitsinje yam'mitsinje ndi mabanki azomera. Nthawi zina, abakha amphaka amasuntha mtunda wautali kuchokera kunyanja.
Makhalidwe a bakha wopalasa
Abakha a Lobe si mbalame zokonda kucheza kwambiri. Mosasamala nthawi yayitali ya moyo wawo, nthawi zambiri amakhala m'magulu ang'onoang'ono. Zikaikira mazira, mbalame zimasonkhana m'mipingo ing'onoing'ono pamadzi am'nyanjayi limodzi ndi mitundu ina ya bakha, makamaka ndi bakha waku Australia. Nthawi yoswana, abakha omwe samakhalira kapena ogwirana amasonkhana m'magulu ang'onoang'ono.
Abakha a Lobe amapeza chakudya akangobatizidwa m'madzi, osachita chilichonse.
Sasamukira kumtunda kawirikawiri, pomwe samamva bwino kwenikweni. Amuna akuluakulu ndi mbalame zam'madera, amathamangitsa opikisana nawo kumalo osankhidwa ndi kulira kwakukulu. Kuphatikiza apo, amuna amayitana akazi ndi kulira kwawo kosamva. M'chilengedwe chawo, mawu ena nthawi zina amafanana ndi phokoso kapena phokoso.
Akaidi, amuna amapanganso phokoso ndi mapazi awo. Akazi ndi mbalame zomwe sizilankhula kwenikweni, zimangodzipereka pakagwa tsoka, zimalumikizana pang'ono. Anapiye akuitanidwa kuti azikondana. Abakha achichepere amalumikizana ndi zisonyezo zomwe zimakhala ndimayendedwe akulira. Masautso akunga mawu a mkazi.
Mosiyana ndi abakha amphaka omwe amakhala kumadzulo kwa nkhondoyi, amuna akumadera akum'mawa samayimba.
Abakha a Lobe samauluka kawirikawiri, koma bwino kwambiri. Kuti akwelele mumlengalenga, amafunikira chilimbikitso chowonjezera ngati mtunda wautali, kenako mbalamezo zimakwera pamwamba pamadzi. Kukwera kumakhala kovuta pambuyo paphokoso lamadzi pamadzi. Ngakhale alibe chidwi chouluka nthawi zonse, abakha amapalasa nthawi zina amayenda maulendo ataliatali. Ndipo mbalame zazing'ono zimasamukira kutali kwambiri kumwera. Ndege zazikulu zimapangidwa usiku.
Kudyetsa bakha
Abakha a Lobe amadyetsa makamaka nyama zopanda mafupa. Amadya tizilombo, mphutsi, ndi nkhono. Amasaka achule, nkhanu ndi akangaude. Amadyanso nsomba zazing'ono. Zomera zimapezeka pachakudya chawo, makamaka mbewu ndi zipatso.
Kusanthula kwa mbalame zambiri ku New South Wales kunapereka zotsatirazi:
- Nyama 30% ndi zinthu zakuthupi,
- Zomera 70%, monga nyemba, udzu ndi rosacee, zomwe zimatsutsana pang'ono ndi zomwe zalembedwa pamwambapa.
Kuswana kwa bakha la Lobe ndikusanja
Nyengo ya bakha wa lobed imayamba makamaka mu Seputembara / Okutobala, koma kukaikira mazira kumatha kuchedwa kutengera mulingo wamadzi. Ziphuphu zimawonedwa kuyambira Juni mpaka Disembala. M'madera ena, abakha otsogozedwa amakhala ndi akazi opitilira makumi awiri pa amuna amodzi. Mkati mwa "akazi" oterewa amakhalanso ndi maubwenzi otayirira, kukwatirana mosalongosoka, ndipo magulu awiri okhazikika kulibe.
M'magulu oterewa, mwayi umakhalabe ndi amuna olimba kwambiri, omwe amawonetsa machitidwe awo. Mpikisano nthawi zina umafika pakutha kwa amuna ofooka ngakhale anapiye.
Chisa chimakhala ngati mbale ndipo chimabisala m'nkhalango zowirira.
Amamangidwa kuchokera kuzomera ndikudzaza ndi imvi-bulauni. Nyumbayi ndi yayikulu kwambiri, yomwe ili kutsika pamwamba pamadzi, m'mabango kapena mumitengo yaying'ono monga typhas, ironwood kapena melaleucas.
Mzimayi amawotchera yekha kwa masiku 24. Mazira ndi obiriwira moyera. Anapiye amawoneka okhala ndi mdima kwambiri pansi ndi zoyera pansi. Abakha achichepere amatha kubereka chaka chimodzi. Zaka zakukhala m'ndende zitha kukhala zaka 23.
Bakha wamatabwa amafalikira
Bakha wokhala ndi lobed amapezeka ku Australia. Amapezeka makamaka kumwera chakum'mawa ndi kumwera chakumadzulo kwa kontrakitala, komanso ku Tasmania. Kafukufuku waposachedwa wa DNA mwa anthu osiyanasiyana, komanso machitidwe osiyanasiyana okwatirana, akutsimikizira kukhalapo kwa ma subspecies awiri. Subpecies yovomerezeka:
- B. l. lobata imafalikira kumwera chakumadzulo kwa Australia.
- B. menziesi amapezeka kumwera chakum'mawa kwa Australia (pakati), South Australia, chakum'mawa kwa Queensland, ndi kumwera ku Victoria, komanso ku Tasmania.
Mkhalidwe wotetezera bakha
Bakha wokhala ndi lobed si nyama yomwe ili pangozi. Kugawikaku ndikosiyana kwambiri, koma kwanuko mitundu iyi imapezeka kwambiri m'mabesi a Murray ndi Darling. Palibe chidziwitso chokhudza bakha la bakha la mainland, koma zikuwoneka kuti pali kuchepa pang'ono kum'mwera chakum'mawa kwa malo omwe ngalande zam'madzi zimayambitsidwa. M'tsogolomu, machitidwe oterewa ndiwopseza kwambiri malo okhala bakha wambiri.
