Bakha wowoneka bwino (Dendrocygna guttata) ndi wa banja la bakha, dongosolo la Anseriformes.
Pali dzina lina la mtundu uwu - Dendrocygna tacheté. Mitunduyi idakonzedwa mu 1866, koma sinaphunzire mokwanira. Bakha adatchulidwa ndi kupezeka kwa mawanga oyera omwe ali pakhosi, pachifuwa ndi mbali zamthupi.
Zizindikiro zakunja kwa bakha wowoneka bwino
Bakha wamawangamawanga amakhala ndi thupi lolimba masentimita 43-50, mapiko a masentimita 85 mpaka 95. Kulemera kwake ndi magalamu pafupifupi 800.
"Kapu", kumbuyo kwa khosi, kolala, pakhosi - imvi - kamvekedwe koyera. Pachifuwa ndi m'mbali mwake mumakhala mopaka bulauni, chokutidwa ndi mawanga oyera ozunguliridwa ndi malire akuda, omwe amakula ndikamayandikira thupi. Malo akulu kwambiri komanso owoneka bwino, omwe ali m'mimba, amawoneka akuda, atakutidwa ndi zoyera. Mapiko ndi kumbuyo - bulauni yakuda ndi m'mbali mopepuka pabuka bulauni, mdima pakati.
Kuphatikiza pa mitundu iyi yosiyanasiyananso, chodalitsacho ndichachikuda.
Mbali yapakati yamimba ndiyoyera mpaka kumtunda. Pamwamba pa mchira ndi bulauni yakuda. Bakha wamawangamawanga amakhala ndi masaya ofiira owoneka bwino komanso mlomo wofiirira. Miyendo ndi yayitali, ngati abakha onse amtengo, imvi yakuda ndi kansalu konyezimira. Iris ya diso ndi yofiirira. Amuna ndi akazi ali ndi mtundu wofanana wa nthenga.
Kugawidwa kwa bakha wokhathamira
Bakha wa mabanga ake amapezeka ku Southeast Asia ndi Australia (Queensland). Amakhala ku Indonesia, Papua New Guinea, Philippines. Ku Southeast Asia ndi Oceania, mitunduyi imakhala kuzilumba zazikulu za Philippines ku Mindanao ku Basilan, ku Indonesia imapezeka ku Buru, Sulawesi, Ceram, Amboine, Tanimbar, Kai ndi Aru. Ku New Guinea, imafikira kuzilumba za Bismarck.
Malo okhala bakha wokhala ndi mawanga
Bakha wamawangamawanga amapezeka mchigwa. Zapadera za moyo ndi zakudya zamtunduwu zimalumikizidwa ndi nyanja ndi madambo, ozunguliridwa ndi madambo ndi mitengo.
Makhalidwe a bakha wowoneka bwino
Ngakhale panali bakha wochuluka kwambiri (10,000 - 25,000 anthu) monsemo, biology ya zamoyozo sizinaphunzirepo kwenikweni. Mitunduyi imakhala moyo wongokhala. Mbalamezi zimapezeka awiriawiri kapena m'magulu ang'onoang'ono, nthawi zambiri zimakhala ndi mitundu ina ya abakha. Amakhala panthambi za mitengo yomwe ikukula m'mbali mwa nyanja kapena zigwa zosaya.
Mdima usanagwe, abakha akuthwa amasonkhana m'magulu a mbalame nthawi zina mazana angapo, ndikugona pamwamba pamitengo yayikulu youma. M'malo omwewo amadyera masana. Zambiri pazakudya ndizochepa, koma, zikuwoneka kuti, abakha akuthwa amadya msipu wochepa ndikuthira m'madzi, kutulutsa chakudya. Mtundu uwu uli ndi miyendo yayitali yokwanira kukhala yabwino m'madzi ndi pamtunda. Ngati ndi kotheka, mbalamezi zimamira pansi pamadzi nthawi yayitali. Pangozi, amabisala m'nkhalango zowirira.
Abakha amtundu wa Arboreal amakhala akugwira ntchito masana, amasunthira kumalo amadzulo usiku komanso m'mawa.
Pouluka, imapanga phokoso lamphamvu m'mapiko ake. Amakhulupirira kuti phokoso lotere limabwera chifukwa chakusowa kwa nthenga zouluka kwambiri mu mbalame, chifukwa chake amatchedwanso abakha a mzere. Abakha omwe ali ndi mawanga nthawi zambiri amakhala mbalame zochepa kwambiri kuposa mitundu ina yambiri ya dendrocygnes. Komabe, mu ukapolo, akuluakulu amalumikizana ndi anzawo ndi mawu ofowoka komanso obwerezabwereza. Amathanso kutulutsa kufuula kwamphamvu.
Kuswana bakha wamawangamawanga
Nyengo ya abakha akuthwa omwe amawotchera amatambasula malinga ndi nthawi, monga zimachitikira mbalame zonse zomwe zimakhala kumwera kwa New Guinea. Zimakhala kuyambira Seputembala mpaka Marichi, ndipo zimaswana kwambiri kumapeto kwa nyengo yamvula mu Seputembara. Bakha wowongoka mzungu nthawi zambiri amasankha mitengo ikuluikulu ya mitengo kuti apange mazira.
Monga abakha ena ambiri, mtundu uwu umapanga awiriawiri kwanthawi yayitali.
Komabe, ndizochepa zomwe zimadziwika pokhudzana ndi kubala kwa mbalame, amakhala moyo wachinsinsi kwambiri. Clutch ikhoza kukhala ndi mazira 16. Makulitsidwe amatenga masiku 28 mpaka 31, omwe amafanana ndi nthawi yayitali yolandidwa kwa anapiye mumitundu ina ya dendrocygnes.
Kudya bakha wamawangamawanga
Abakha omwe ali ndi mawanga amadyera kokha pazakudya zamasamba ndipo nthawi zina amangogwira nyama zam'mimba mwangozi mwamwayi. Amadya mbewu, masamba a zomera zam'madzi, ndikuzichotsa ndi milomo yawo pamene mutu ubatizidwa posaya.
Kuteteza kwa bakha wamawangamawanga
Chiwerengero cha abakha akuthwa pafupifupi 10,000-25,000, ofanana ndi anthu pafupifupi 6,700-17,000 okhwima. Chiwerengero cha mbalame chimakhalabe chokhazikika popanda umboni uliwonse wakuchepa kapena kuwopsezedwa. Chifukwa chake, abakha amipaka yayitali ndi amtunduwo, kuchuluka kwake sikumabweretsa mavuto.
Mitunduyi ndiyambiri, koma mbalame zimapezeka m'malo omwe mwina ndi madera otsogola pazilumba zina. Abakha omwe ali ndi mawanga ambiri ndi mbalame zosowa kwambiri m'magulu a akatswiri azinyama ndi malo osungira nyama, izi zikufotokozedwera ndi mawonekedwe apadera a biology ndi zisa.
