The cuckoo ishiri ine mukurumbira uye inozivikanwa nemaitiro ayo anonyengera. Mushure mezvose, munhu angadana sei maitiro eshiri inokanda zvipembenene mumatendere edzimwe shiri, izvo zvisingabatanidzi chete mukutsamira pamutsipa we "vabereki vokurera", asiwo kuuraya vana vavo chaivo. Uku kuzvitutumadza chaiko. Mwari ngaasadaro munhu akafanana hunhu negaka. Zvisinei, vanaamai vakadaro variko.

Vanhu vazhinji vanofarira kuti cuckoo inotaridzika sei. Bva, mubvunzo unofadza zvikuru uye kuupindura inhau yorukudzo, sokunge zvakadaro. Iyo cuckoo ine chimiro chekutaura, saka haigone kuvhiringika nedzimwe shiri. Kubva pakutanga, iwe unofanirwa kuziva kuti shiri iyi ndeyei, kwainogara, zvichingodaro.

Ndiani cuckoo uyu?

Makuka ishiri inowanikwa munyika. Anogara muAsia nedzimwe nyika. Kunyangwe kuSouth Africa, anogara. Ndosaka anogona kukanganisa hupenyu hwevane minhenga chero kupi zvako pasi pano. Heino shiri yakadaro, inobuda. Kana iwe uchida kutsanangura kuti cuckoo inoratidzika sei, saka hapana chakaoma pamusoro payo. Kuyeuka ruzivo kuri nyore kwazvo. Muhurefu, muviri wake unosvika 40 centimita. Iyi ishiri yakati kurei.

Kana ikatwasanudza mapapiro ayo, ipapo kutambanuka kwawo kuchava hafu yeurefu hwemuviri weshiri iyi. Saka nekubhururuka haambofi ane matambudziko. Pamusana pemaatomical features of the bapiro, hazvishamisi kuti nhiyo dziri pasi pemwedzi dzinokura kusvika pakuti dzinogona kubhururuka kubva mudendere uye kukanganwa nezvevabereki vavo vanovagamuchira nokusingaperi.

Pasinei nehukuru hwakakura, cuckoo ishiri yakareruka. Huremu hwayo hunosvika pahuwandu hwemagiramu zana nemakumi maviri. Kana zvichienzaniswa nezvimwe zvinhu, zvinozoitika kuti huremu hwecuckoo hahuna kunyanya kudarika hwenharembozha. Kana kuti, imwe chete, kana isu tiri kutaura nezve yakajairika nharembozha inogona kuisa mamwe maapplication uye kusefa paInternet. Zviri pachena kuti foni yenguva dzose yakareruka. Asi kune smartphone, uremu uhwu hwakajairwa.

Iyo cuckoo ine muswe wakareba kwazvo. Inobatsirawo shiri pakubhururuka. Kana mapapiro akakosha kuitira kuti arambe ari mumhepo, achisvetuka pamusoro pevhu, ipapo muswe unoshanda sechidzoreso. Ndosaka cuckoo inogona kunzi inogoneka shiri. Zvose, sezvazvinobuda, nekuda kwemuswe. Kureba kwayo kunosvika masendimita makumi maviri. Ndiko kuti, zvinosvika kuti hafu yemuviri weshiri ndiyo muswe. Chimbofungidzira.

Pasinei nekureruka kwemuviri, yakanyanya kukora. Kazhinji, zvinoshamisa kuti shiri yakadaro ine zviyero zvakakura zvakakwana uye muviri wakaoma unoshanduka kuva chiedza. Iyo cuckoo inoratidzwawo nemakumbo ayo maduku. Pamwe inobatsira kurema. Zvisinei, shiri inofanira kuva chiedza. Zvikasadaro, mhepo haingoisimudza uye haizobhururuka. Kungoti shiri dzakakura kudaro dzakareruka, ndizvo zvinoshamisa.

Kazhinji, cuckoo ine muviri wakaoma uye makumbo mapfupi. Uku ndiko kusanganiswa kwezvinhu inoratidza shiri semufananidzo unozivikanwa, uye inonyatsozivikanwa zvokuti kunyange mumutauro weRussia inofarirwa.

Makuka, sedzimwe shiri, pane zvepabonde dimorphism. Kana mumwe munhu asingazivi, saka iyi ndiyo misiyano yekunze pakati pemurume nemukadzi. Sexual dimorphism inoonekwawo nevanhu. Ichi chiratidzo chekukura kwehupenyu hweimwe mhando. Chii chinosiyanisa murume nemukadzi? Kufanana nedzimwe mhuka dzakawanda, hono dzinogona kusiyana nehadzi dzine minhenga. Ngatienzanise varume nevakadzi maererano nehunhu. Asi kubva pakutanga zvakakosha kunyora izvo zvinosiyanisa zvimiro zvevarume pakuonekwa.

1. Musana nemuswe. Muvanhurume, nhengo idzi dzemuviri dzine minhenga yegrey yakasviba. it inoita kuti cuckoo isaonekwe kune dzimwe shiri pasi pemamwe mamiriro. Shiri idzi dzinofanirwa kukwanisa kuzvivanza kwete chete kuti zvikara zvisaone, asiwo kuisa nekuronda dendere. Saka hauzowani mavara akajeka mu cuckoos.
2. Goiter nehuro zvine ruvara rwegrey. Musanganiswa uyu unotaridzika zvakanaka pamwe chete nerima grey mavara emusana nemuswe. Zvinoitika kuti iyi iruvara rushoma, rwunoita kuti cuckoo ive shiri ine shaded.
3. Muviri wese wakachena une mitsetse yakasviba.

Madzimai ane brownish tones, kusiyana nevarume. Ndivo kuti mhuka imwe inogona kusiyaniswa kubva kune imwe. Zvisinei, kana vose varume nevakadzi vari vaduku, ipapo kusiyana kwavo kwemavara epabonde hakusi kunyanya kuoneka. Havasati vagadzira pigment, saka ruvara rweshiri duku rwakajeka grey uye kune mavanga muviri wese. Kazhinji, isu takafunga kuti cuckoo inotaridzika sei. Zvino ngatimbotaura zvishoma nezvezvimwe zvinhu zvoupenyu hwake.

upenyu

Mutsara wekuti "wolf wolf" inogona kutsiviwa zvachose ne "lone cuckoo". Icho chokwadi ndechekuti mapere anowanzo tungamira mararamiro emagariro, ane mapaketi umo mune yakajeka hierarchy. Chii chisingagoni kutaurwa nezve cuckoos. Vanorarama hupenyu hwega. Dzinotsvaka zvokudya kweupenyu hwavo hwose uye dzinokurukura nedzimwe shiri chete kana dzichifanira kukwirana. Havavaki matendere. Munhu wose anozviziva makudo anokandira mazai uye kumanikidza dzimwe shiri kuti dziyamwise nhiyo dzadzo.

Iyo cuckoo inongobatikana mukutsvaga chikafu chega. Haisi nguva yekutandara inonakidza, handizvo here? Zvakadaro, ichi ichokwadi. Zvakare, shiri idzi dziri kutsvagira nhiyo dzadzo vabereki. Vanonyatsotarisa matendere edzimwe shiri kwenguva yakareba, nekuda kwekuti maitiro akawanda e psychophysiological anoonekwa mumuviri wavo, nekuda kwekuti mazai akafanana nemuvara seaya akakandwa mazai.

Chii zvino chinobatsira cuckoo? Uye chokwadi chekuti anodya makonye kana zvimwe zvipembenene. Izvi zvinobatsira sango zvakanyanya. Panguva imwecheteyo, shiri dzinodya dzinogona kuparadza zvikuru hupenyu hwe cuckoo. Saka kudzorwa kwehuwandu hwevanhu kunoitika nekuda kwekuvapo kweshiri dzinodya mudondo.

Kubereka

Hukama hwewanano hunoita makudo hunonzi polygyny. Murume anodana cuckoos ane ruzha runokosha, nekuda kwekuti shiri dzinokanda mazai 4-5 pagore. Chaizvoizvo, kutaurirana pakati pecuckoos kunoitika panguva yekubereka. Kuburikidza nekutaurirana hakurevi kutaurirana zvakanyanya sekudyidzana. Kukurukurirana mumhuka ndiko kuchinjana kwezviratidzo, uye kudyidzana ndiko kupanana kwezviito.

Mushure mekunge zai rapinda mudendere, rinokura mavhiki mashoma nekukurumidza, nekudaro makuko anozvarwa, avo vakakura nekanoverengeka kupfuura vabereki vavo vokurera, vanofanira kudyisa ichi chishamiso. Mazai asina kufanira cuckoo anoraswa. Chokwadi ichi takadzidziswa kuzvikoro. Asi mazuva makumi maviri gare gare, makuka akakura anobva mudendere uye haachaoni vabereki vavo.

Makuchi ecuckoo anoita sei mumatendere?

Cuckoos vanozvibata, zvinozoitika, zvine hutsinye zvine chekuita kwete nemazai chete, asiwo kuvabereki vavo. Ivo vakanyanya kufanana nevechiri kuyaruka mapenzi avo vakatopfuura vabereki vavo muhukuru, asi panguva imwecheteyo, uropi hahuna kunyanya kusiyana nevana. Ndizvo zvimwe chete nemakuko. Vanoda zvine hasha kutariswa kwese kwavari.

Ndeapi maitiro ehunhu hwe cuckoo maitiro?

1. Shiri iyi haina hasha pachayo. Kunyangwe maitiro ehuku dzemhuka iyi inogona kutsanangurwa nekuti ivo vanofanirwa kurarama neimwe nzira pasina amai.
2. Cuckoos vakasimba vega uye vanozvida. Zvisinei, vanogona kurarama zvakanaka.

Sezvo zviyero zve cuckoo zvakakura zvakanyanya kupfuura zvemamwe huku, saka vanoda zvimwe zvokudya zvakawandakupfuura mamwe nhiyo kuchengetedza hupenyu hunogutsa nehuremu hwemuviri hwakakodzera. Naizvozvo, huku dzehuku dzinovhimawo kuti dzitore chikafu kubva kune dzimwe huku dzakakwanisa kurarama. Heino shiri yakadaro inofadza - cuckoo. Hunewo zvakanakira. Kana huwandu hwemhuka ipi neipi yakakura kwazvo, saka izvi zvakaipa. Uye cuckoos inokanganisa huwandu hwedzimwe shiri kwete kunyange kuburikidza neketani yekudya, asi nenzira inonakidza yakadaro.

Hakuna mhuka dzisina basa. Pane zvakavanzika chete zvisina kuwanikwa zvepasirese mhuka.
