Mitundu ya Swan - Mitundu ya Swans

Nkhono ndizodziwika bwino komanso zimadziwika bwino, ndipo pomwe pali mitundu isanu ndi iwiri yokha ya nkhumba padziko lonse lapansi, imafalikira m'makontinenti asanu (palibe swans amapezeka ku Antarctica kapena Africa). Izi zimapangitsa kuti zikhale zina zapamadzi zomwe zimadziwika bwino padziko lonse lapansi, ndipo zingakhale zosangalatsa komanso zolinga zenizeni kuti mbalame zokhumba zowonjezera zikhale zowonjezera mndandanda wa zamoyo .

Chifukwa Chake Timadziwa Zokongola Kwambiri

Ngakhale kuti pali mitundu yochepa chabe ya mbalame, mbalamezi zimatumizidwa kuzilombo, zinyama, minda yamaluwa ndi malo kuzungulira dziko lapansi, zomwe zimapangitsa kuti azidziwika bwino komanso kuzizindikira.

M'madera ambiri, kuthawa nkhuku kumatha kusambira ndi nyanjayi zakutchire, makamaka m'madzi a m'matawuni kapena m'mphepete mwa nyanja, m'mphepete mwa nyanja, m'mphepete mwa nyanja kapena m'madzi ena abwino. Mitundu iliyonse imakhala yosiyana.

Nkhumba zimagwiritsidwanso ntchito ngati mbalame zophiphiritsira pofuna kugonana. Iwo ndi otchuka pazokwati ndipo nthawi zambiri amagwiritsidwa ntchito pa Tsiku la Valentine, zikondwerero ndi maulendo ena achikondi. Ngakhale nkhumba zomwe zimagwiritsidwa ntchito pazinthu zophiphiritsira sizili mitundu yambiri, ngakhale mtundu wa swan umakhala wosiyana ndi wowoneka ngati mbalame imodzi.

Chimene Chimachititsa Kuti Swans Ali Osiyana

Ngakhale kuti mtundu uliwonse wa zinyama ndi wosiyana, onsewa amagawana zinthu zina zomwe zimawonekera kuti ziwoneka ngati nkhumba. Nkhumba zonsezi ndi za banja la mbalame, pamodzi ndi atsekwe ndi abakha, koma sizidzasokonezeka chifukwa cha zidzukulu zawo. Nkhono zazikuluzikulu zam'madzi zimakhala ndi mitundu yochepa kwambiri ya mbalame, mtundu wa swan, wokhala ndi masentimita 101, ndipo mapiko ake amakhala mamita masentimita 152 ndipo amatha kulemera masentimita 8 (3.6-5.4) kg).

Ng'ombe yamkokomo ndi yaikulu kwambiri kuposa mitundu yonse ya nyama, yomwe imakhala yaitali masentimita 152, ndi mapiko a masentimita 241 ndipo imakhala yolemera makilogalamu 6.8-13.6. N'zoona kuti pali kusiyana kwakukulu pakati pa a swans ndi aamuna omwe ali aakulu komanso olemera kuposa akazi.

Ukulu wawo wonse si chinthu chokha chimene chimapangitsa swans kukhala apadera.

Zina kuposa mbalame yakuda, mbalamezi zili ndi mvula yoyera. Zitsimba zawo ndizitali komanso zochepa, ndipo nthawi zambiri zimagwira makosi awo mumakono okongola kapena S-mawonekedwe, kupatula kuthawa, pamene makosi awo atambasuka. Mitu yawo ndi yaing'ono, ndipo miyendo yawo ndi yofupika kuposa momwe zingaganizire mbalame zazikuluzikulu. Pouluka, swans angamawoneke bwino komanso osasangalatsa ndi matupi awo olemera, olemera ndi mapazi aatali, koma ndi okoma komanso okongola pamene akusambira.

Ndi ndalama zowonongeka, nkhumba zimakhala zowonongeka ndipo zimatha kudutsa mumatope, namsongole, udzu ndi madzi kuti akwaniritse zakudya zawo zowonjezera . Amadya tirigu, mbewu, udzu, masamba, rootlets komanso malo amchere a zomera zomwe amatha kuzipeza. Ndi miyendo yawo yaitali, iwo amatha kugwira ntchito m'madzi akuya pamphepete mwa nyanja pamene akufikira zomera zowonongeka. Izi zimapangitsa swans kukwera bwino mu malo omwewo monga mbalame zam'madzi zomwe sizikhoza kufika mpaka swans.

Tsogolo la Achinyamata

Ndiwopindulitsa ndipo ndikutsimikizira kuti palibe mtundu wa swans omwe tsopano akuwoneka kuti akuopsezedwa kapena kuopsezedwa. Izi sizikutanthawuza kuti zowonongeka sizikufunikira, komabe. Mofanana ndi mbalame zonse, swans ali pachiopsezo chachikulu cha kuwonongeka kwa malo okhala, poizoni , kuwononga chilengedwe, ziweto zowonongeka, kuphulika kwa matenda, mitsempha ya nsomba ndi zina zambiri zomwe zingawononge anthu.

Ngakhale masiku ano anthu ambiri padziko lonse lapansi ali ndi thanzi labwino komanso labwino, sizingasinthe kwambiri kuti chiwerengero chawo chikhale chopambana. Ndili ndi mitundu yochepa yokhala ndi mitundu yosiyanasiyana padziko lapansi, nkofunika kutenga njira zowatetezera onse, kapena swans angakhalepo tisanazindikire, ndipo nkhumba zokha zomwe tingasangalale nazo ndizithunzi zophiphiritsira pa mikate yachikondi.
