Bakha wa pinki (Malacorhynchus membranaceus) ndi wa banja la bakha, dongosolo la Anseriformes.
Zizindikiro zakunja za bakha wokhala ndi pinki
Bakha wokhala ndi pinki amakhala ndi masentimita 45. Kutalika kwa mapiko ake kumakhala pakati pa 57 mpaka 71 cm.
Kulemera kwake: 375 - 480 magalamu.
Mtundu wa bakha wokhala ndi milomo yofiirira yopanda mawonekedwe okhala ndi matumbo ozungulira sungasokonezeke ndi mitundu ina. Nthengayo ndi yosalala komanso yosadziwika. Chophimba ndi kumbuyo kwa mutu ndizofiirira. Malo ozungulira akuda kwambiri kapena ozungulira amapezeka mozungulira diso ndikupitilira kumbuyo kwa mutu. Mzere wozungulira wozungulira wozungulira wazungulira mpandawo. Malo ang'onoang'ono apinki, osawoneka akuthawa, amapezeka kuseli kwa diso. Masaya, m'mbali ndi kutsogolo kwa khosi ndi malo ang'onoang'ono a imvi.
Pansi pake pa thupi pamayera ndi mikwingwirima yakuda kwambiri yakuda, yomwe imakulanso mbali. Nthenga za mchira ndi zotumbululuka chikasu. Thupi lakumtunda ndi lofiirira, nthenga ndi mchira wa nthenga ndi zakuda bulauni. Mzere woyera umachokera pansi pa mchira ndikufika ku miyendo yakumbuyo. Nthenga za mchira ndizotakata, kumalire ndi zoyera zoyera. Mapikowo ndi ozungulira, abulauni, okhala ndi malo oyera oyera pakati. Zoyalalazi ndizoyera mtundu, mosiyana ndi nthenga zamapiko zofiirira kwambiri. Nthenga za abakha achichepere ndizofanana ndi mbalame zazikulu.
Malo a pinki pafupi ndi khutu lakutsegulira samawoneka pang'ono kapena kulibe palimodzi.
Amuna ndi akazi ali ndi mawonekedwe akunja ofanana. Ikuuluka, mutu wa bakha wokhala ndi pinki ndiwokwera, ndipo mlomowo umatsikira pansi. Abakha amasambira m'madzi osaya, amakhala ndi mikwingwirima yakuda ndi yoyera pathupi lawo, mlomo waukulu ndi nthenga zapadera.
Malo okhala bakha wapinki
Abakha okhala ndi makutu apinki amapezeka m'zigwa zamkati mwa nkhalango pafupi ndi madzi. Amakhala m'malo opanda matope pamadzi, nthawi zambiri osakhalitsa, omwe amapangidwa nthawi yamvula, pamadzi osefukira osefukira. Abakha okhala ndi pinki amakonda madera onyowa, madzi otseguka kapena matupi amadzi amchere, komabe, magulu akulu a mbalame amasonkhana m'madambo otseguka. Ndi mtundu wofalitsidwa kwambiri komanso wosamukasamuka.
Abakha okhala ndi mapiko obiriwira nthawi zambiri amakhala mbalame zakumtunda, koma amatha kuyenda maulendo ataliatali kuti akapeze madzi ndikufika kugombe. Makamaka kuyenda kwakukulu kumapangidwa mzaka za chilala chachikulu.
Kufalikira kwa bakha wokhala ndi pinki
Abakha okhala ndi makoswe ofiira amapezeka ku Australia. Amagawidwa ponseponse kum'mwera chakum'mawa kwa Australia komanso kumwera chakumadzulo kwa kontrakitala.
Mbalame zambiri zimakhazikika m'makonde a Murray ndi Darling.
Abakha okhala ndi makutu apinki amapezeka m'maboma a Victoria ndi New South Wales, omwe amakhala ndi madzi abwino okhala. Komabe, mbalame zimapezekanso m'magulu ochepa kuchokera pagombe lakumwera kwa Australia. Monga mitundu yosamukasamuka, imagawidwa pafupifupi konsekonse ku Australia kupitirira gombe.
Kukhalapo kwa bakha wamtunduwu kumatengera kupezeka kwa madzi osasinthasintha, episodic, osakhalitsa omwe amapangidwa kwakanthawi kochepa. Izi ndizowona makamaka mdera louma lomwe lili pakatikati ndi kum'mawa kwa Australia, kunyanja yakum'mawa ndi kumpoto kwa Tasmania, komwe kupezeka kwa abakha okhala ndi pinki sikupezeka kwenikweni.
Makhalidwe amtundu wa bakha wokhala ndi pinki
Abakha a pinki amakhala m'magulu ang'onoang'ono. Komabe, m'madera ena amapanga masango akuluakulu. Nthawi zambiri amasakanikirana ndi mitundu ina ya bakha, makamaka, amadyetsa ndi imvi (Anas gibberifrons). Bakha wokhala ndi makutu a pinki akapeza chakudya, amasambira m'madzi osaya m'magulu ang'onoang'ono. Amamira pafupifupi kwathunthu osati mulomo wokha, komanso mutu ndi khosi m'madzi kuti zifike pansi. Nthawi zina abakha ama pinki amaika gawo lina la thupi lawo pansi pamadzi.
Mbalame pamtunda zimakhala kanthawi pang'ono pansi, nthawi zambiri zimakhala pamphepete mwa malo osungira, pamitengo yamitengo kapena pa chitsa. Abakha awa sali amanyazi konse ndipo amalola kuti awafikire. Zikakhala zoopsa, amanyamuka ndikupanga ndege zozungulira pamadzi, koma mofulumira khalani chete ndikupitiliza kudyetsa. Abakha okhala ndi makutu apinki si mbalame zaphokoso kwambiri, komabe, amalumikizana pagulu ndikulira kangapo. Yamphongo imatulutsa mkokomo wowawasa, pomwe yaikazi imatulutsa chizindikiro chobisalira pothawa komanso pamadzi.
Kuswana bakha wa pinki
Abakha okhala ndi khungu lowoneka ngati pinki amaberekera nthawi iliyonse pachaka, ngati madzi osungira ali oyenera kudyetsa. Mtundu wa bakhawo umakhala wosakwatiwa ndipo umapanga magulu awiri okhazikika omwe amakhala limodzi kwa nthawi yayitali mbalame imodzi isanamwalire.
Chisa ndi chomera chodzaza, chobiriwira bwino, chodzaza ndi madzi ndipo chili pafupi ndi madzi, pakati pa tchire, mdzenje la mtengo, pa thunthu, kapena chimangogona pa chitsa chachitali pakati pamadzi. Abakha okhala ndi khungu la pinki nthawi zambiri amagwiritsa ntchito zisa zakale zomwe zimamangidwa ndi mitundu ina ya mbalame zosaoneka:
- zodzikongoletsera (Fulicula atra)
- chonyamulira arborigène (Gallinula ventralis)
Nthawi zina abakha okhala ndi pinki amatenga chisa ndi chisa pamwamba pa mazira amtundu wina wa mbalame, kuthamangitsa eni ake enieni. Pazifukwa zabwino, mkazi amayikira mazira 5-8. Makulitsidwe amatha pafupifupi masiku 26. Mzimayi yekha ndiye amakhala pampata. Zazikazi zingapo zimatha kuikira mazira 60 pachisa chimodzi. Mbalame zonse, yaikazi ndi yaimuna, zimadyetsa ndi kuswana.
Kudya bakha wa pinki
Abakha okhala ndi khungu la pinki amadya m'madzi ofunda osaya. Uwu ndi mtundu wapadera kwambiri wa bakha, womwe umasinthidwa kuti uzidyera m'madzi osaya. Mbalame zimakhala ndi milomo yomwe ili ndi milomo yopyapyala ya lamellas (grooves) yomwe imawalola kusefa zomera zazing'ono kwambiri ndi nyama zazing'ono zomwe zimadya kwambiri. Abakha okhala ndi khungu la pinki amadya m'madzi ofunda osaya.
Kuteteza bakha wa pinki
Bakha wamphako ya pinki ndi mitundu yambiri, koma kuchuluka kwa anthu kumakhala kovuta kulingalira chifukwa cha moyo wosamukasamuka. Kuchuluka kwa mbalame ndizokhazikika ndipo sizimayambitsa nkhawa zilizonse. Chifukwa chake, njira zoteteza chilengedwe sizigwiritsidwa ntchito pamtundu uwu.
