Zizindikiro zakunja kwa teal Salvadori

Teal Salvadori ndi bakha wamng'ono wokhala ndi kukula kwa thupi pafupifupi ndipo amalemera pafupifupi magalamu 342.

Imasiyana ndi mitundu ina ya bakha ndi mutu wake wofiirira wakuda ndi mlomo wachikaso. Nthengazo zili ndi mawangamawanga ndi mikwingwirima ndi mawanga akuda bii ndi oyera. Abakha ena aku Australia, ofanana ndi mkaka wa Salvadori, ali ndi mitu yowala bwino komanso nthenga zolimba zofiirira. Miyendo ku Salvadori teal, hue lalanje. Mkazi ndi wamwamuna ali ndi nthenga zofanana.

Salvadori teal amafalikira

Teal Salvadori ndi mitundu yopezeka m'mapiri a New Guinea (Papua, Indonesia ndi Papua New Guinea). Atha kupezeka pachilumba cha Weijo ku Indonesia, koma izi ndi lingaliro chabe, popeza teal wa Salvadori sanawoneke m'malo awa.

Malo okhala tiyi a Salvadori

Masamba a Salvadori amapezeka m'malo otsika kwambiri. Amapezeka pamtunda wa mamita 70 mu Lakekamu Basin, koma nthawi zambiri amafalikira pachilumbachi m'malo aliwonse okhala ndi mapiri. Bakha amakonda mitsinje ya rafting mwachangu komanso mitsinje, ngakhale imawonekeranso munyanja zosayenda. Malo okhala matumba a Salvadori ndi ovuta kufikira komanso achinsinsi. Amakhala achinsinsi ndipo mwina amakhala usiku.

Makhalidwe a tiyi Salvadori

Masamba a Salvadori amakonda kukhala kumapiri.

Mbalame zawonedwa panyanja pamtunda wa mamita 1650 ku Foya (West New Guinea). Amatha kuyenda m'nkhalango zowirira kuti apeze malo abwino okhala. Ngakhale malo okhala abwino amawonetsedwa pamitunduyi kumtunda kwa 70 mpaka 100 mita, nthawi zambiri abakhawa amafalikira osachepera 600 mita komanso kumtunda.

Chakudya cha tiyi wa Salvadori

Teal Salvadori ndi abakha omnivorous. Amadyetsa, kugubuduzika m'madzi, ndi kulowa m'madzi posaka nyama. Chakudya chachikulu ndi tizilombo ndi mphutsi zawo, ndipo mwina nsomba.

Njira yoberekera Salvadori

Teals a Salvadori amasankha malo okhala ndi zisa pafupi ndi dziwe. Mbalame zimakhazikika m'mphepete mwa mitsinje yothamanga komanso mitsinje ndi nyanja zamapiri. Nthawi zina amakhala pamitsinje yomwe imayenda pang'onopang'ono ndi chakudya chochuluka. Mtundu uwu wa abakha siwokhazikika ndipo pali anthu amodzi kapena awiri okha a mbalame zazikulu. Malo oberekera amakhala ndi masamba osiyanasiyana omwe amatengera momwe zinthu ziliri. Mwachitsanzo, mbalame ziwiri zinkakhala m'dera lalitali mamita 1600 m'mbali mwa mtsinje wa Baiyer, ndipo pa Mtsinje wa Menga, malo okhala ndi mamita 160 ndi okwanira mbalame.

Mtundu wa abakhawa umakonda kukhazikika pamiyendo ing'onoing'ono, ndipo imawonekera kambiri pamitsinje ikuluikulu.

Nthawi yoswana imayamba kuyambira Epulo mpaka Okutobala, mwina mu Januware. Pazifukwa zabwino, zotchinga ziwiri pachaka ndizotheka. Chisa chimakhala pamtunda kapena pafupi ndi gombe muudzu wandiweyani, nthawi zina pakati pa miyala. Clutch imakhala ndi mazira awiri kapena anayi. Amayi okhaokha amakola kwa masiku pafupifupi 28. Kukula kumatha kuchitika masiku osachepera 60. Mbalame zonse ziwiri zazikulu zimayendetsa ankhandwe, yaikazi imasambira ndi anapiye atakhala kumbuyo kwake.

Mkhalidwe wosungira tiyi wa Salvadori

Teal Salvadori amadziwika ndi IUCN ngati mtundu wosatetezeka (IUCN). Chiwerengero cha anthu padziko lonse lapansi pakadali pano chikuyembekezeka kukhala pakati pa 2,500 ndi 20,000 achikulire ndipo kuchuluka kwa mbalame zosowa zikuyembekezeka kupitilira kuchepa chifukwa tiyi wa Salvadori wasinthidwa kukhala malo apadera kwambiri, chifukwa chake ziwerengero zake zidzakhalabe zochepa.

Zifukwa zochepetsera kuchuluka kwa teal Salvadori

Chiwerengero cha matumba a Salvadori chikuchepa pang'onopang'ono.

Kuchepa kumeneku kumadza chifukwa cha kuwonongeka kwa malo okhala, makamaka chifukwa cha kusefukira kwa mitsinje, makamaka pambuyo pomanga makina opangira magetsi komanso kutukula kwa migodi ndi kudula mitengo. Ngakhale izi zimawoneka m'malo ochepa okha. Kusaka ndi kusaka agalu, mpikisano wamasewera pakusodza nawonso kumawopseza kukhalapo kwa mitunduyo. Kulima nsomba zam'madzi mumitsinje yoyenda mwachangu kumatha kubweretsa chiopsezo ku teal yosowa chifukwa cha mpikisano wazakudya.

Njira zosungira tiyi wa Salvadori

Teal Salvadori Mitunduyi imatetezedwa ndi malamulo ku Papua New Guinea. Abakha amtunduwu ndi omwe amafufuzidwa mwapadera. Pachifukwa ichi ndikofunikira:

  • Chitani kafukufuku wamitsinje m'malo omwe mumapezeka tiyi wa Salvadori kuti mupeze kuchuluka kwa momwe anthropogenic imakhudzira mbalame.
  • Kuti muwone kuchuluka kwakusaka kwa kuchuluka kwa abakha ochepa.
  • Fufuzani momwe mphamvu zamagetsi zamagetsi zimakhudzira mtsinjewo kumtunda ndi kutsika, komanso zotsatira za kuwonongeka kwa zinthu kuchokera kumigodi ndi kudula mitengo.
  • Fufuzani mitsinje ndi nsomba zochuluka kwambiri kuti mupeze zotsatira zakupezeka kwa nsombazi pamitengo yambiri.
  • Onani zomwe zimakhudza chilengedwe panyanja ndi mitsinje.
