tsekwe ndi ya banja la mbalame zam'madzi. Mwa njira yake yamoyo ndi mawonekedwe ake, amafanana kwambiri ndi tsekwe, koma amasiyana ndi mtundu wa nthenga, komanso zikopa zakuda ndi milomo.
Masiku ano pali atsekwe osiyanasiyana, ndipo ena mwa iwo ndi osowa kwambiri kotero kuti si malo onse osungira nyama omwe angakwanitse kukhalamo. Pali nkhani imodzi yodziwika, yomwe idachitika zaka makumi asanu ndi atatu mphambu makumi atatu za zana la makumi awiri, pomwe nthumwi za Soviet Union zidasinthanitsa mbalame ziwiri zazing'ono zapakhosi lofiira kukhala chimpanzi ndi njovu yaku India yolemera matani atatu.
Mawonekedwe ndi malo a tsekwe
Mwachilengedwe, pali mitundu inayi yayikulu ya atsekwe, kuphatikiza: Canada, Wakuda, Wofiira ndi Wofiyira. Wofiira tsekwe - m'buku lofiira la Russia, ndipo pakadali pano ndi pakati pa anthu omwe atsala pang'ono kutha.
Zina mwazisaka zamtunduwu ndi Yamal, Gydan ndi Taimyr Peninsula. M'madera ena, mutha kukumana ndi nthumwi za bakhawo pokhapokha atawuluka kwambiri. Njira zosunthira za atsekwe okhala ndi mabere ofiira zimadutsa kumpoto chakumadzulo kwa Kazakhstan, South-East Ukraine komanso mumitsinje ya Nadym, Pura, Tobol ndi Ob.
Tsekwe zofiira ndi mwini thupi mpaka masentimita 55, ndipo kulemera kwa achikulire nthawi zambiri sikupitilira ma kilogalamu 1.2. Mapiko a mbalame amasiyana kuyambira masentimita 35 mpaka 40, ndipo utoto wake umakhala wakuda kwambiri ndi tizidutswa toyera kapena tofiira.
Maluso osambira bwino komanso kusambira pamadzi. Amakhazikika, monga lamulo, m'malo okwera kwambiri komanso ouma kwambiri m'nkhalango ndi tundra, osati kutali ndi madzi. Mbalamezi zinali pafupi kutha chifukwa cha kusaka kwakukulu komwe anthu akumaloko, omwe amawamenya ndi mfuti ndikuzigwira ndi maukonde apansi, nthenga ndi nyama.
Pachithunzicho muli tsekwe za mawere ofiyira
Barnacle tsekwe zolembedwa mu International Red Book, koma sizili m'gulu la nyama zomwe zatsala pang'ono kutha. Kukula kwa mbalamezo ndikokulirapo pang'ono kuposa atsekwe, ndipo kulemera kwake kumatha kupitilira ma kilogalamu awiri. Amasiyana ndi achibale ena amtundu wa mitundu iwiri, chifukwa amaoneka oyera kuyambira pansi, komanso akuda kuchokera kumwamba.
Khosi, mphumi ndi mutu wake mbali zake ndi zoyera. Amadziwa kusambira, kudumphira m'madzi, kuwuluka komanso kuthamanga mwachangu, nthawi zambiri kuthawa motere ku zoopsa. Amapezeka ku Scandinavia Peninsula, komanso m'mbali mwa nyanja ya Greenland. Kwa malo obisalira, imasankha mapiri okhala ndi miyala ikuluikulu komanso malo otsetsereka.
Mu chithunzicho tsekwe wamkulu
Tsekwe zakuda imawoneka ngati tsekwe zazing'ono, zomwe zimawoneka zakuda kumbuyo ndi zoyera kutsogolo. Amakhala omasuka pamadzi komanso pamtunda, amasambira mwachangu ndikuyenda movutikira pamtunda. Mbalameyi siyidziwa m'madzi, ndipo imatha kungofanana ndi abakha, kugubuduzika mozungulira kuti ipeze chakudya kuchokera pansi.
Mapazi ndi milomo ya atsekwe ndi akuda, dera lam'mimba ndi loyera. Mitunduyi imakhala makamaka pazilumba zomwe zili m'nyanja ya Arctic komanso m'mphepete mwa nyanja zosiyanasiyana za Arctic. Amakonda chisa m'munsi mwa zigwa za mitsinje komanso m'mphepete mwa nyanja zomwe mulibe udzu.
Pachithunzicho muli tsekwe zakuda
Canada tsekwe wopezeka ku United States ndi Canada. Mwa kukula kwake, mbalameyi imaposa abale akuda ndi amphongo ofiira, ndipo kulemera kwake kumatha kupitilira ma kilogalamu 6.5. Mapiko a mamembala awa a banja la bakha ndiwosangalatsanso ndipo amakhala pakati pa 125 mpaka 185 sentimita.
Khosi ndi mutu wa atsekwe aku Canada ndi akuda ndi zonyezimira. Mtundu wa thupi nthawi zambiri umakhala wotuwa, koma umatha kukhala ndi chokoleti kapena ma wavy. Malo okhala mbalame amakhala makamaka ku Alaska ndi Canada komanso kuzilumba za Canada Arctic Archipelago.
Kujambula ndi tsekwe waku Canada
Chikhalidwe ndi moyo wa atsekwe
Atsekwe, ngakhale atakhala amtundu wanji, ndi mbalame zachilengedwe ndipo amakonda kukhala pagulu. Pamodzi, mbalamezi zimauluka kupita kumalo ozizira ndi kumbuyo, zikulumikizana nthawi yayitali ndipo sizisakanikirana ndi mitundu ina ya atsekwe ndi abakha. Amuna nthawi zambiri amapita molt kuposa akazi.
Nthawi ya molting imadziwika ndi atsekwe chifukwa cholephera kuuluka; chifukwa chake, kuti adziteteze kwa anthu osiyanasiyana oyipa, mbalame zimayenera kukhala m'magulu akulu. Adani akuluakulu a atsekwe panthawi yachisa ndi osaka ndi nkhandwe, zomwe zimawononga zisa ndikugwira anapiye ndi akulu omwe. Nthawi zambiri mbalameyi imathawa kwa olakwa chifukwa chothamanga, yomwe ndi yabwino kwambiri.
Pakudya, mbalamezi zimangokhalira kulankhulana, kulankhulana. Liwu lawo limamveka kwambiri ndipo limamveka bwino ngakhale kutali. Mofanana ndi kukhosomola kapena kuguwa kwa galu. Goose wofiira, monga mitundu ina, imamanga chisa chaka ndi chaka m'malo omwewo, pomwe mpaka magulu awiri ndi theka amasonkhana nthawi yomweyo.
Kudyetsa mbalame
Zakudya za atsekwe ndizochulukirapo, ndipo zimaphatikizapo mitundu yosiyanasiyana ya herbaceous zomera ndi molluscs, tizilombo ta m'madzi ndi nkhanu. Mbalamezi zimakonda msondodzi wakum'mwera (catkins ndi masamba), zokwawa clover, sedge, bluegrass ndi mitundu yonse ya ndere.
Zakudya za atsekwe zimadalira nyengo yake, chifukwa nthawi yodyetsa chakudya cha mbalame chimakhala masamba, ndipo panthawi yosamukira m'mbali mwa nyanja, amakonda kukola nyama zawo kuchokera m'madzi.
Kuswana ndi chiyembekezo cha moyo wa atsekwe
Momwe miyoyo ya tsekwe makamaka m'malo ophatikizira misika yawo, mtunda wa pakati pa zisa nthawi zambiri sumapitilira mamitala angapo. Mbalame zimakula msinkhu wa zaka ziwiri. Pafupifupi nthawi yomweyo, awiriawiri amapangika.
Mwambo wokutira ndiwosangalatsa komanso wamphokosomo: amuna amalira mokweza ndikutenga mawonekedwe owoneka bwino kwambiri kuti akope chidwi cha akazi. Mkazi akugwira ntchito yomanga chisa. Amapezeka nthawi zambiri pamapiri otsetsereka ndi m'matanthwe m'malo osafikika nyama zolusa.
Zida za chisa ndi ndere, moss ndi udzu wouma. Pansi, atang'ambidwa ndi wamkazi kuchokera pachifuwa chake ndi m'mimba mwake, amafalikira mpaka pansi. Mu zowalamulira imodzi, yaikazi imaikira mazira mpaka asanu, ndipo anapiye ake amatuluka patatha milungu inayi.
pafupifupi moyo wa zaka mbalame atsekwe ali ndi zaka pafupifupi 25, komabe, milandu yambiri imadziwika pomwe mbalame zomwe zidagwidwa zimakhala zaka 30 kapena kupitilira apo.
Chitetezo cha tsekwe
Kusaka atsekwe akuda, amabere ofiyira komanso nkhokwe lero nkoletsedwa. Anthu okhala mdera la Russia, nthawi ina, adazunzika kwambiri pakukula kwa mafuta ndi gasi.
Popeza mbalamezi zimangokopa, izi sizinawapindulitse, ndipo anali atatsala pang'ono kutha chifukwa cha kuwonongedwa kwakukulu ndi alenje ndi opha nyama mosayenera. Chifukwa chake, pakadali pano, ndikosavuta kuwona tsekwe pachithunzichi kapena pitani kumalo osungira nyama kumene kuli mbalamezi.
