Lalela izwi lesixuku sase-Australia.
Izimpawu zangaphandle zezingulube zase-Australia.
Idada lase-Australia linobukhulu obucishe bube ngu-49 cm, amaphiko asuka kumasentimitha angama-65 kuye kwangama-70. Isisindo: 900 - 1100 g. Umlomo wesilisa ungama-38 - 43 mm ubude, bese kuthi owesifazane abe ngu-36 - 41 mm ubude.
Leli dada - umtshuzi kwesinye isikhathi ubizwa ngabantu bendawo ngokuthi "idada elinamehlo amhlophe". Lesi sici sibalulekile ekuhlonzweni kwezinhlobo. Izimpaphe zesilisa zifana nombala wekhava lezimpaphe zezinye izinhlobo zamadada, kodwa umugqa wedada lase-Australia ovela emlomeni ucace bha. Izimpaphe zinsundu kakhulu kunezinhlobo ezifanayo.
Izimpaphe ekhanda, entanyeni nasemzimbeni zinombala onsundu onsundu. Emaceleni anombala onsundu ngokubomvu, emuva nomsila kumnyama, kuqhathaniswa nomsila nezimpaphe zesisu esisemaphakathi, ezimhlophe. Ngezansi kwamaphiko kumhlophe ngomngcele omncane onsundu.
Umthethosivivinywa ungwevu omnyama ngomugqa osobala ngokuluhlaza ngokumpunga. Izinyawo nemilenze zinombala onsundu ngokumpunga, izipikili zimnyama. Umthethosivivinywa ubanzi, mfushane, uyisicaba, uyanwebeka kancane ubheke esiqongweni futhi wehlukaniswa nemarigold encane. Ekhoneni lekhanda kunezimpaphe ezinde, eziphakanyiswe ngesimo sokhonkolo. Ku-drake omdala, i-crest ingama-3 cm ubude, kowesifazane omdala mfushane. Izinyoni ezisencane azinamagoda. Kunezimpaphe zemisila eziyishumi nane.
Umbala wezimpaphe kowesifazane uyafana nowesilisa, kodwa umbala ombala onsundu ogcwele kakhulu ngomphimbo ophaphathekile. Iris yeso. Umugqa osesondweni useduze. Owesifazane mncane ngobukhulu kunomlingani wakhe. Kungaba nokuhluka kwesizini kumbala wezimpaphe isikhathi esifushane se-molt. Amadada amancane anemibala efana neyensikazi, kodwa ekhanyayo, nsundu ngokubomvu, isisu simnyama, sinamabala.
Izindawo zokuhlala zedada lase-Australia.
Idada lase-Australia litholakala emachibini ajulile anendawo enkulu ngokwanele, kunamanzi abandayo. Amadada angabonakala nasemigodini enezitshalo eziningi. Ngezikhathi ezithile bavakashela amadlelo nezindawo ezilinywayo ukuzondla.
Ngaphandle kwenkathi yokuzalanisa, zitholakala emachibini, ezindaweni zokuhlanza indle, emaxhaphozini, emachibini, ezindaweni ezingasogwini lwamachibi anosawoti, emahlathini amaxhaphozi kanye nasemizimbeni yamanzi angenacala. Bavame ukuvakashela amachibi asezintabeni aze afike kumamitha ayi-1 150 ngaphezu kogu lolwandle, njengamachibi ase-East Timor.
Ukuziphatha kwesixuku sase-Australia.

Amabili abumbana ngokushesha okukhulu, lapho nje ukukhuphuka kwamanzi kunikeza izimo ezinhle zokuzalisa.
Imiboniso yamadada ase-Australia ayijwayelekile kakhulu ngenxa yokwehluka okukhulu kakhulu kwemvula.
Amadada alezi zinhlobo anamahloni kakhulu futhi aqaphe ngokweqile. Ngokungafani nezinye izinhlobo ezihlobene nohlobo, amadada ase-Australia akwazi ukusheshe asuke futhi asuke ngokushesha okukhulu, okuyinzuzo enkulu lapho kunosongo lokuhlaselwa yizilwane ezidlayo: amagundane amnyama, amaqhuqhuva ama-herring, izinyoni ezidla inyama. Ukuze aphile, amadada adinga imizimba yamanzi enamazinga anele amanzi ukuze ondle ngokuntywila ngekhanda emanzini. Lapho amadada ebhukuda, ahlala ajule ngokwanele emanzini, kuthi lapho etshuza, ashiye ngaphezulu kuphela ngemuva komzimba wawo ngomsila onamathele phezulu. Lapho kukhona imizimba yamanzi unomphela, amadada ase-Australia ahlala phansi. Kepha ngesikhathi sesomiso isikhathi eside, baphoqeleka ukuba bahambe amabanga amade, beshiya izindawo zabo zokuhlala unomphela. Ngaphandle kwenkathi yokuzalanisa, amadada ase-Australia ayizinyoni ezithule kahle. Ngesikhathi sokukhwelana, eyeduna ikhipha ikhwelo. Owesifazane uyehluka kumlingani wakhe ngezimpawu zezwi, wenza uhlobo oluthile lokugaya futhi anikeze u-quack onamandla, onokhahlo lapho esemoyeni.
Ukudla kwedada lase-Australia.
Amadada ase-Australia adla kakhulu ekudleni kwezitshalo. Badla imbewu, izimbali nezinye izingxenye zezitshalo, ama-sedge notshani obuseduze kwamanzi. Amadada nawo adla izinambuzane ezingenamgogodla, ama-molluscs, ama-crustaceans, izinambuzane. Babamba izinhlanzi ezincane. Esifundazweni saseVictoria ezwekazini eliseningizimu-mpumalanga ye-Australia, amadada ase-Australia achitha u-15% wesikhathi sawo edinga ukudla kanti amanye angama-43% aphumule. Iningi lezilwane ezidliwayo, ama-95%, zitholakala ngokuntywila futhi kuphela u-5% wokudla okuqoqwa ebusweni bamanzi.
Ukuzala nokuzalela idada lase-Australia.

Isidleke sise osebeni lwechibi noma esiqhingini esifihlwe kahle ezimileni eziminyene. Yakhiwe ngezitshalo zasemanzini noma ezinamanzi amancane. Kubukeka sengathi ipulatifomu embozwe ifakwe phansi.
I-Clutch iqukethe amaqanda anemibala engu-9 - 13 emhlophe - enokhilimu. Kwezinye izimo, isidleke siqukethe amaqanda angafika kwayi-18, avela njengomphumela wokuzalisa isidleke futhi abekwa ngamanye amadada. Amaqanda makhulu, ngokwesilinganiso esingu-5 - 6 cm futhi anesisindo esingama-gramu angama-50. Abesifazane abafukamela kuphela abamba izinsuku ezingama-25 kuya kwezingama-27. Kuvela amatshwele, embozwe ukukhanya phansi ngaphezulu kombala onsundu onsundu kanye ne-tint ephuzi ngezansi, ithoni ehlukahlukene phambi komzimba. Zikhula ngokushesha, zithola isisindo kusuka ku-21 kuye ku-40 amagremu. Amadada amadala azala unomphela. Azikho izibalo ngempilo ende yamadada amadala.

Kukhona usongo lokushintsha kwendawo yokuhlala ngenxa yokudonswa kwamaxhaphozi ezindaweni zokuzalela zedada lase-Australia.
