Izi si funso chabe, chifukwa m'madera ena amaona amangokhala, pamene ena amati iliyonse yozizira, Ptah ili kwinakwake ntchentche.

Mu nkhani imeneyi, ndipo kwenikweni si yapafupi. Asayansi akukhulupirira kuti ulendo wake kupambana kuzungulira wagtail dziko kuyamba penapake mu Africa. Makamaka anthu onse kuti zimene zikuchitika pa izo kuchokera kwinakwake kum'mwera. Choncho, amene amenewa wagtail: zosamukasamuka mbalame kapena ayi?

Ornithologists kuti ochuluka osiyanasiyana waukulu mbalame izi zimawapangitsa flights yozizira zonse. Koma kum'mwera kwa Ulaya ndi ku Africa pali anthu amene ali paliponse mu yozizira musati amauluka.

Nkhani ndi malo nyengo kusintha zingachitike chifukwa chakuti mwa mtundu uwu wa amaposa wa polymorphism, pamene mbalame ku malo osiyana kuyang'ana yosiyana. Iwo akhoza kusokonezedwa ndi mitundu ina, ndi chifukwa mkangano.

Mu dziko lathu, ndi wagtail - mbalame zosamukasamuka amene anabwerera kunyumba pa chiyambi cha kutsegula kwa mitsinje ya madzi oundana. Monga ulamuliro, izo zimachitika penapake kumapeto kwa March.

Mwa njira, atangotha kubera mbalame amakonda kukhala pafupi ayezi kupita ndi mtsinje thawed, kuwapangitsa anthu mwanthabwala kunena kuti chimaswa ayezi wagtail. Zosamukasamuka mbalame kapena ayi - ife tadutsa kale asanaganize, koma zimene zimachitika mu mabacteria kusintha a ku Central Asia?

Sitikudziwa mosadziwa ukukhudza nkhani imeneyi. Kumadera amenewo nyengo wankhanza kwambiri (ngati zachilendo mmene zingamvekere). chakuti miyezi yotentha nthawi zambiri yodziwika ndi kutentha silifooketsa anthu ofuna ndi dzuwa, pamene yozizira mulole, pa ukulu wake Timasangalalanso Siberians ngakhale mbadwa.

A chitsanzo chapadera - Mongolia. M'chilimwe kutentha angayandikire madigiri 60 Celsius m'nyengo yozizira kupita kutali pansi pa chizindikiro madigiri 20. Popeza khalidwe mbalame wagtail (zithunzi za amene m'nkhani) wotere?

Zinali ndiye kuti amasonyeza wapadera zake zonse! Mu Mongolia chomwecho, pali pafupifupi khumi subspecies wa kholo mbalame, umenenso maonekedwe awo ndi zizolowezi ndi wosiyana kwambiri ndi iye.

Choncho, ena mwa iwo ali pafupifupi kuderako, m'nyumba zawo zokha pa nkhani ya nyengo wankhanza kwambiri, ndipo ena wagtails kupanga ndege mtunda wautali, ngakhale chilimwe, n'zosavuta kupanga hybrids latsopano.

Khalidwe chabe chimene chimagwirizanitsa mamembala onse a mitundu ya padera ndi kukopa awo zachilendo kwa anthu, ndi opangidwa mitunda. Ngati pafupi ndi malo a m'derali pali mzinda waukulu, pafupifupi onse mbalame kukhazikika mu mzere wake.

Mwa njira, pali oddity wina: m'midzi lalikulu wagtail zambiri kusintha makhalidwe awo, ndi mbali ya anthu, ngakhale m'nyengo yozizira amakhalabe pamalo omwewo. Ndithudi, izi zingathe kufotokozedwa ndi chuma cha chuma chakudya, koma kuti mbalame zina musati muzichita zimenezo!

Apa pali mkazi, wagtail. Zosamukasamuka mbalame kapena zovuta kunena motsimikiza, monga izo zingakhoze bwanji zinthu zingapo.
