Ukukhala akunzima. Idada likaSviyaz liyisisulu esilula sabaqaphi bezinyoni. Ngokubeka amathegi ezinyoni ukulandelela imizila yokufuduka, ososayensi babhekana nobunzima bokubamba izinyoni. "Ukuzwa" ukuthi kukhona okungahambi kahle, izilwane zikhuphukela emoyeni.
Idada liyazulazula
Sviyaz ayihlali ikwazi ukundiza njalo. Njengommeleli wehansi, idada likhipha ngokushesha, lilahlekelwe yizo zonke izimpaphe zokundiza ngasikhathi sinye. Ezinye izinyoni zizilahlekisela kancane kancane. Ngenkathi ezinye ziwa, ezinye ziyakhula. Umthakathi, elahlekelwe yikhono lokukhuphukela emoyeni, ucasha ezihlahleni. Yilapho-ke abakhala khona inyoni.
Incazelo nezici zedada le-sviyaz
Idada liyazulazula - inyoni enosayizi ophakathi nendawo efinyelela kumasentimitha angama-51 ubude futhi enesisindo esilingana nekhilogremu. Izimpiko ezinamaphiko zingamasentimitha angama-76-90. Osayizi bamaphakathi phakathi kwe-mallard ne-teal. Lawa amanye amadada amabili ajwayelekile eRussia.
Iduna lesilisa (kwesokudla) neduna lesivyaz
Esithombeni iwigi ibonakala njengenyoni enhle. Izimpaphe ezibomvu-mpunga zifakwe imicu. Ngesikhathi sokuzala, umbala uyashintsha kwabesilisa. I-goiter iba mpunga ngokubomvu, isisu simhlophe, futhi okuthengiswayo nezinhlangothi kumnyama.
Inhloko nangemuva kudwetshwe i-chestnut. Zonke ezinye izimpaphe zihlala mpunga. Kunophawu olubanzi kusuka emlonyeni kuya kuNape wenyoni. Imhlophe, igolide, iphuzi. Ngakho-ke udrake embethe kusuka entwasahlobo kuye phakathi nehlobo. Ngemuva kwezinyoni molt. I-dimorphism yezocansi iyeka ukubizwa.
Umzimba wedada uqinile futhi uminyene. Iqhawe lendatshana lehlukaniswa namanye amadada ngesiphongo esiphakeme, intamo emfushane uma iqhathaniswa nezihlobo, umsila omude, okhonjwe, kanye noqhwaku kufushane ngamadada.
Ukufika komthakathi emanzini
Lapho amadada evula amaphiko awo, imigqa yezimpaphe ze-emerald iyabonakala. Kunamabala amhlophe ngaphezulu. Lokhu kuwuphawu lwabesilisa abavuthiwe ngokocansi. Kodwa-ke, kubantu abadala, amamaki amhlophe njengeqhwa ayanyamalala.
Indlela yokuphila nendawo yokuhlala
Nyakazisa inyoni okhulumayo. Imisindo eyenziwe yizilwane iqhathaniswa nokukhala kwento yokudlala yenjoloba. Abesilisa banezwi elihlukile, linamandla ngokwengeziwe. Lolu ucingo lomshado. Kungazwakala phakathi neqhwa elincibilikayo. Lesi yisikhathi sokufika kwamadada avela emazweni afudumele.
Izwi lomthakathi kwaba yisizathu phakathi kwabantu sokubiza idada ngekhwela. Abanye babiza i-heroine yalesi sihloko ngokuthi imifino. Lokhu kungenxa yokudla kwama-wiggles. Udla izimila kuphela.
Lalela izwi ledada elizulazulayo
Idada alifuni ukutshuza ulwelwe, ukuhlala eduze nezinye izinyoni zamanzi. Umthakathi ucosha utshani obuphansi obubambe emilenzeni yama-swans, noma bamane nje abakuboni njengokudla kwabo.
Umthakathi endizeni
Ziphindela ezweni lazo, izinyoni zihlala emadamini amancane emifuleni yezikhukhula. USviyaz, ngasendleleni, ubizwa ngenye indlela ngokuthi idada lomfula. Ukhetha amadamu avulekile ngaphandle kweziminyene.
Izinyoni ikakhulukazi zikhethe amachibi eWestern Siberia, izindawo ezisezansi zemifula i-Ob, iVolga ne-Ural. Kukhona amadada akhetha amadamu ane-duckweed. Amanye amakoloni amadada akhethe amachibi e-tundra yolwandle. Kodwa-ke, izinyoni nazo ziyafika e-Arctic. Amadada andiza lapho, azulazule efuna ukudla.
Izinhlobo zedada leSviyaz
I-heroine ye-athikili ayinayo i-subspecies. Kodwa-ke kukhona idada elihlobene, elicishe lingahlukaniswa neqhawekazi le-athikili. Ama-ornithologists kuphela angahlukanisa abesifazane. Imayelana ne-wiggler yaseMelika. Izinhlobo zaseRussia zibizwa nge-Eurasian.
Iwigi yaseMelika
Isangoma saseMelika sisabalele ezwenikazi laso njengaleso lase-Eurasia emazweni aso. Phakathi kwamadada kukhona iRed Book, kepha i-heroine yalesi sihloko ayibhalwanga ngisho nasezincwadini zesifunda. Lokhu kudlala ezandleni zabazingeli. Njengoba benelayisense, bazingela bezulazula ngaphandle kwesithiyo.
Ukuzingelwa Kwabathakathi
Ukuba sengozini kwedada ngesikhathi se-molting akusetshenziswanga kuphela ngama-ornithologists. Abanye abazingeli nabo basebenzisa lesi sikhathi. Kwabanye, umoya wezemidlalo ungaphezu kwakho konke. Zizingela izilwane zisencane, ngokuqinile ephikweni.
Khweza amadada kufakiwe. Ekuzungezeni ukukhohlisa abazalwa kabusha yenza njengesimemo sokujoyina. Umzingeli kufanele agcwalise isilwane esigxishiwe ngokukhala okuyisici samadada. Kuyisayensi ephelele ukubalingisa. Ngakho-ke, abazingeli abaningi bathola ukukhohlisa ngomthakathi... Njengemfoloko yokuhlenga, inika ngokunembile "inothi" lenyoni.
Abathakathi abakhohlisayo
Iningi lama-decoy libiza kusuka kuma-ruble ayi-1200. Kodwa kukhona izinguqulo isabelomali kubiza ruble 600. Izitolo zokuzingela nazo zinikela ngezifundo zevidiyo zabazingeli. Noma kunjalo, kukhona izinto ezifanayo kwi-Intanethi.
Ividiyo isitshela ukuthi ungayakha kanjani i-skradok. Kufanele itholakale eduze kwedada lokukhohlisa. Kulokhu, i-wigon yangempela akufanele ibone umzingeli. Yena, endaweni yakhe yokukhosela, kufanele athathe isikhala esincane, kodwa abe ntofontofo ukuze adubule ngesikhathi esikahle.
Kwesinye isikhathi kuyadingeka ukucasha endaweni yokucasha ebusuku. Uma kucatshangelwa ukuthi ukuzingelwa komthakathi kuqala ekuqaleni kwentwasahlobo, bagqoka amabhulukwe agwedlile bathathe namajakhethi oboya.
Ukuze bangalindeli ize, baya emadlelweni agcwele izikhukhula. Kufanele ukufihlwa kubo phakathi kwamaqhubu angonakalisiwe wokufinyelela okuncane. Amadamu ahlolwa kuqala ezikebheni.
Ukuzingelwa Kwabathakathi
Ekukhetheni izindawo ezithile zemizimba yamanzi, idada elinyakazayo alikwazi ukubikezela. Emachibini, abazingeli baqondiswa "izibuko" okunzima ukufinyelela kuzo phakathi kwamahlathi emithi. Kubo umdlalo ushiya esimweni sezulu esinomoya.
Lapho bengayitholi indawo eyomile abangacasha kuyo, abazingeli, njengezinyoni, bacasha emihlangeni esikebheni. Kubalulekile ukuzingela amadada akhohlisayo lapha entwasahlobo. Umsindo we-drake decoy uthathwa njengokukhala kowesifazane.
Ngakho-ke, ekuzingeleni kwentwasahlobo, ikakhulukazi amadada abesilisa ayazingelwa. Ehlobo nasekwindla, abazingeli bamane balinde kuze kuvele izilwane emanzini noma zindiza phezu kwendawo.
Ukuzala kanye nesikhathi sokuphila
Izidleke ezizulazulayo zitholakala osebeni oluvulekile nolunezitshalo, ezimfundeni zase-taiga. Lapho izinyoni zithola izindwani zotshani namahlumela okulala. Ubuningi besidleke buphansi. Amadada ayithatha emzimbeni wayo.
Umama uzulazula ngamadada
Amaqanda azulazulayo ayi-beige noma ukhilimu. Esinye sezici zempumelelo nokwanda kwalezi zinhlobo eziningi zezingane. Amadada azalela amaqanda ayi-10-12 ngasikhathi sinye. Ubude, zifinyelela kumasentimitha ayisithupha.
Amaqanda amadada
Amachwane avela emaqandeni ezinsukwini ezingama-22-25. Ukunakekela inzalo kulele kunina. Imibiko yokubamba iqhaza ekufukameleni nasekukhuliseni inzalo yamadrake ayivelakancane. Uma amaphuphu ekwazi ukusinda ebuntwaneni bawo futhi angabanjwa abazingeli, ama-wiggles afinyelela eminyakeni engu-13-15 ubudala.
