Baby swans - swan chicks
Swans dzinochochonya kubva mumazai adzo ndiwo magumo anoshamisa ekurindira kwakakweverwa kwakatsungirirwa nevakadzi veshanje kweinodarika mwedzi. Pamusoro pekutsakatika kwakanyanya, peni (uye plunger) iri kutsvagawo chikafu. Vanongopedza mazuva mashoma vari mudendere nevana vadzo vasati vatanga ruzivo rwavo rwehupenyu.
Mwana anozvarwa
Pashure pokunge vatamburira kuti vasununguke kubva muzai, vana vanenge vachiri vakafukidzwa nenamo inovapoteredza mukati mezai uye inovadzivirira pamvura zhinji inoumbwa nezai racho. Kupera kwenamo uku kunovapa kunyorova kwavanoita pavanenge vachangochochonywa, asi kunokurumidza kuparara kwemaawa mashoma anotevera sezvo kunenge kwaoma uye vashoma vanozokwesha pavanenge vachitsikirira mai naamai vavowo zvinhu zvedendere.
Mushure mekuoma, bhinzi riri mucheche rinobva raita gireyi, rakapfava zvinoita kuti macygnet akwezvedze kuvaoni.
Huremu hwemwana weshan panguva yekuchechenya hunosvika 64% yehuremu hwezai pakutanga kukandira (iyo yakashaikwa 36% inosanganisirwa mukurema kwegoko rezai, membranes, mvura / mwando uye kurasikirwa nekuda kwe metabolism) uye zvakare 2,5% yehuremu hwayo hwekupedzisira kana ari munhu mukuru.
Vana swans vari panjodzi zvisingaite panguva ino; Vane zvishoma zvavanotya chero chinhu, saka yavo vanaamai nanababa zvirokwazvo vachapfuurira kurudzi rwavo rwakakotsekana, kunyange ruvengo, runofadza rwekupindira panguva ino.
Chinhu chinoita kuti vese plunger nepeni vanyatso kuziva kufurirwa kubva kunze imhaka yekuti vadiki vavo vanoda kuzvironga kana "kuzvimisikidza" pane chimwe chinhu chavanonamatira zvinotevera zvitanhatu. batisisa ichava mwedzi, inenge.
Vachavimba naamai vavo navanababa vavo kuti vavatungamirire kuzvokudya, kuvapa dziviriro, nokusika chiremera nokuda kwavo migumisiro anogona.
Pashure pokunge mwana aberekwa, amai nababa vanoita matsindo anotevedzana ayo vana vacheche vanoronga kuti vabvume vabereki vavo zvinonzwika. (Imwe neimwe swan inoburitsa yayo yakasarudzika odhiyo, yakafanana ne vanhu vane inzwi ravo. Iyo stylus ine odhiyo yakakwira zvishoma pane iyo plunger.)
Kuchochonya kweshavi ndiko kwatinoti presocial hatching. Izvi zvinoratidza kuti inogona kuona, kufamba, uye kuzvidyisa, pamwe nekuzvichenesa. Ichange iine pasi (inotonhorera-yakafanana nemvere) uye zvirokwazvo haizodi hunenge huwandu hwekubata kubva kuna vanaamai vayo nemadzibaba ayo ingadiwa nenhiyo yehove kana yebhuruu tit.
Kunyange zvakadaro, mwana wemucheche achave anoshanda zvakanyanya kubva pakutanga, kunyangwe ivo vachiri kuda kutarisirwa kwakawanda uye nhungamiro kubva kuvabereki vavo.
Zuva rekutanga remwana mucheche
Zuva rokutanga rehupenyu rinoiswa mudendere naamai nanababa pamwe chete nedzimwe mhuka duku.
Pazuva rekutanga, mwana wembavha achada hake kuramba ari pasi penzvimbo yedumbu raamai kana mumapapiro ake akatambanudzwa zvishoma.
Sezvakakurukurwa muchikamu cheSwans Incubating Eggs, vana swans vanotanga kuita ruzha kwemaawa makumi mana nemasere vasati vachechenya.
Aya manzwi anogadzirwa nekamwana kacheche chikamu chakakosha chekukurukurirana pakati pacho, mamwe mabhinzi emwana uye nevabereki vake.
Hazvina kujairika kuti vana vasingatauri vaberekwe pazuva rekutanga mvura famba. Ivo vachapedza zvamazvirokwazvo maawa avo makumi maviri namana okutanga vari pedyo zvikuru naamai vavo sezvavanopfuurira kuberekesa rudzi rwupi norwupi rwamazai asina kuchochonywa nokuyamwisa vana vavo.
Mhuri yeSwan ine vana 6 vatsva
Muguri kazhinji anoiswa padivi pake - kuti ave nechokwadi chekuchengeteka kwake uye kuti ajairane nemhuri yake itsva.
Nguva nenguva, anofamba munzvimbo iri pedyo nedendere kuti aone kuti hapana “vashanyi” vasingadiwi varipo here.
Zvakare pane yekutanga Zuva richava vana veshani vakazviona kuti vanozvigadzira sei. Kunyange zvazvo iwo ekutanga pasi pasi achidzivirira mvura zvishoma (ivo vanozvarwa vaine downy fluff zvakasiyana neminhenga inozivikanwa), zvinoda kutarisisa uye kutarisa kuti varambe vari muchimiro chakanaka.
Pamusoro pemuswe wavo, swans dzine gland yekuchenesa - mafuta ari mugland iyi anofanira kucheneswa pamusoro kupararira neshiri yose kuchengetedza fluffy layer isapinda mvura.
Chimwe chezvinhu zvekutanga zvavachaita kuramba vachitarisa zvinhu zvakasiyana kuti zvigoneke uye nekudya zvinhu zvishoma, sora diki nezvimwe zvakadaro.
