Izimpawu zangaphandle zedada elinamabala
Idada elinamabala linobude bomzimba obungu-43-50 cm, amaphiko angamasentimitha angama-85-95. Isisindo singama-gramu angama-800.
"Isigqoko", ngemuva kwentamo, ukhololo, umphimbo - ithoni - mpunga - ithoni emhlophe. Isifuba kanye nezinhlangothi kunsundu-kumnyama okotshani, kumbozwe ngamabala amhlophe azungezwe umngcele omnyama, okhula ube mkhulu njengoba usakazeka phansi emzimbeni. Izindawo ezinkulu kakhulu futhi ezibonakala kakhulu, ezisendaweni yesisu, zibonakala zimnyama, zihlangene ngombala omhlophe. Izimpiko nomhlane - nsundu ngombala onsundu ngokukhanyayo ngokubomvu, nsundu maphakathi nendawo.
Ngaphezu kwalombala we-variegated, isibambiso naso sinamachashazi.
Ingxenye emaphakathi yesisu imhlophe ize ifike endunu. Phezulu komsila kunsundu emnyama. Idada elinamabala linezihlathi ezikhanyayo ngokukhanyayo nomlomo o-pink-grey. Imilenze mide, njengawo wonke amadada okhuni, mpunga omnyama onombala opinki. Iris yeso insundu. Owesilisa nowesifazane banombala ofanayo wezimpaphe.
Ukusatshalaliswa kwedada elinamabala

Indawo yokuhlala kwedada elinamabala
Idada elinamabala atholakala emathafeni. Izici zendlela yokuphila kanye nokudla okunomsoco kwalolu hlobo kuhlotshaniswa namachibi namaxhaphozi, azungezwe amadlelo nezihlahla.
Izici zokuziphatha kwedada elinamabala
Yize kunedada elinamabala amaningi (10,000 - 25,000 yabantu) kuyo yonke indawo yokuhlala, i-biology yezinhlobo zemvelo ayifundwanga kangako. Lezi zinhlobo zihola impilo yokuhlala phansi. Izinyoni zitholakala ngababili noma ngamaqembu amancane, imvamisa zinezinye izinhlobo zamadada. Zihlala emagatsheni ezihlahla ezikhula osebeni lwamachibi noma amathafa angajulile.
Ngaphambi kobumnyama, amadada anezinkuni ahlangana emhlanjini wezinyoni kwesinye isikhathi amakhulu ezinkulungwane, futhi achithe ubusuku eziqongweni zezihlahla ezinkulu ezomile. Ezindaweni ezifanayo badla emini. Imininingwane yemikhuba yokudla imfishane, kepha, ngokusobala, amadada anezinkuni adla utshani obufushane futhi achele emanzini, akhiphe ukudla. Lolu hlobo lunemilenze emide ngokwanele ukuba ikhululeke emanzini nasemhlabeni. Uma kunesidingo, izinyoni ziyacwila futhi zihlale ngaphansi kwamanzi isikhathi eside. Uma kunengozi, zicasha ezihlahleni eziminyene.
Amadada anamabala ase-Arboreal ayasebenza emini, ahambela ezindaweni zobusuku kusihlwa nasekuseni.
Lapho indiza, ikhipha umsindo oqinile ophuma ezimpikweni zayo. Kukholakala ukuthi imisindo enjalo ivela ngenxa yokungabikho kwezimpaphe zokundiza ezeqile ezinyonini, ngakho-ke zibizwa nangokuthi amadada ashaywayo Amadada anamabala ase-Arboreal ngokuvamile ayizinyoni ezinomsindo omncane kunezinye izinhlobo eziningi ze-dendrocygnes. Kodwa-ke, ekuthunjweni, abantu abadala baxhumana bodwa ngezimpawu ezibuthakathaka neziphindaphindayo. Futhi ziyakwazi ukukhipha ukukhala okuklabalasayo.
Ukuzalela idada elinamabala
Isikhathi sokufukamela amadada anamachashaza anwetshiwe ngokwesikhathi, njengazo zonke izinyoni ezihlala eningizimu yeNew Guinea. Iqala ngoSepthemba kuya kuMashi, ngenani eliphakeme lokuzalisa ekuqaleni kwenkathi yemvula ngoSepthemba. Idada elinempempe elinamabala livame ukukhetha iziqu zemithi ezingenalutho ukuze zizalele.
Njengamanye amadada amaningi, lolu hlobo lwakha ama-pair angapheli isikhathi eside.
Kodwa-ke, kuncane okwaziwayo ngokuziphatha kwezinyoni, ziphila ngendlela eyimfihlo kakhulu. I-clutch ingaqukatha amaqanda afinyelela ku-16. Ukufukamela kuthatha izinsuku ezingama-28 kuye kwezingama-31, okuhambelana nesikhathi esimaphakathi sokuchanyuselwa kwamachwane kwezinye izinhlobo ze-dendrocygnes.
Ukudla idada elinamabala
Amadada anezinkuni adla kuphela ukudla kwezitshalo futhi ngezikhathi ezithile athatha izinambuzane ezingenamgogodla ezihlala emanzini ngengozi. Adla imbewu, amaqabunga ezitshalo zasemanzini, azikhiphe ngomlomo wazo lapho ikhanda ligxiliswa ekujuleni okujulile.
Isimo sokonga sedada elinamabala
Inani lamadada anezinkuni angaba ngu-10 000-25,000, okulingana nabantu abavuthiwe ababalelwa ku-6 700-17,000. Izinombolo zezinyoni zihlala zizinzile ngaphandle kobufakazi bokuncipha noma izinsongo ezinkulu. Ngakho-ke, amadada anezinkuni anezinhlobo zezinhlobo, inani lazo elingabangeli izinkinga ezithile.
Ububanzi bukhulu impela, kepha izinyoni zitholakala ezindaweni ezingaba yizindawo ezingathuthukisa umkhiqizo wezolimo kwezinye iziqhingi. Amadada anezinkuni ayizinyoni ezingandile kakhulu emaqoqweni ama-ornithologists nasemamuoos, lokhu kuchazwa ngokutholakala kwezinhlobo zezinto eziphilayo kanye nokwakha izidleke.
