Ukadaulo Wotsatira Zinthu Wathandiza Kulemba Kusamuka Koyamba Kwa Ana a Whimbrel Osalekeza Kuchokera ku Iceland Kupita Kumadzulo kwa Africa

Mu sayansi ya mbalame, kusamuka kwa mbalame zazing'ono mtunda wautali kwakhalabe gawo lovuta kwambiri pa kafukufuku. Tengani Eurasian Whimbrel (Numenius phaeopusMwachitsanzo. Ngakhale asayansi afufuza kwambiri momwe anthu akuluakulu amasamukira padziko lonse lapansi, akusonkhanitsa zambiri, chidziwitso chokhudza ana aang'ono sichikupezeka.

Kafukufuku wakale wasonyeza kuti mbalame zazikulu zotchedwa whimbrel zimaonetsa njira zosiyanasiyana zosamuka nthawi yoberekera mu Epulo ndi Meyi zikamayenda kuchokera kumalo awo oberekera m'nyengo yozizira kupita kumalo awo oberekera. Zina zimauluka mwachindunji kupita ku Iceland, pomwe zina zimagawa ulendo wawo m'magawo awiri ndikuyima. Pambuyo pake, kuyambira kumapeto kwa Julayi mpaka Ogasiti, mbalame zambiri zazikulu zotchedwa whimbrel zimauluka mwachindunji kumalo awo oberekera m'nyengo yozizira ku West Africa. Komabe, mfundo zofunika kwambiri zokhudza ana aang'ono—monga njira zawo zosamuka ndi nthawi—zakhalabe chinsinsi kwa nthawi yayitali, makamaka panthawi yoyamba kusamuka kwawo.

Mu kafukufuku waposachedwa, gulu lofufuza la ku Iceland linagwiritsa ntchito zipangizo ziwiri zowunikira zopepuka zomwe zinapangidwa ndi Global Messenger, mitundu ya HQBG0804 (4.5g) ndi HQBG1206 (6g), kuti ziwunikire ma whimbrel 13 a ana. Zotsatira zake zinawonetsa kufanana kochititsa chidwi pakati pa ma whimbrel a ana ndi akuluakulu panthawi yoyamba kusamukira ku West Africa.

Mofanana ndi akuluakulu, anyamata ambiri okonda kuuluka mosalekeza kuchokera ku Iceland kupita ku West Africa adakwanitsa kuchita bwino kwambiri poyenda mosalekeza kuchokera ku Iceland kupita ku West Africa. Komabe, kusiyana kwakukulu kunawonedwanso. Achinyamata nthawi zambiri ankakwera ndege kumapeto kwa nyengo kuposa akuluakulu ndipo anali ndi mwayi wochepa wotsatira njira yolunjika yosamuka. M'malo mwake, ankaima pafupipafupi panjira ndipo ankauluka pang'onopang'ono. Chifukwa cha otsata a Global Messenger, gulu la ku Iceland linajambula, koyamba, ulendo wosamuka wosakhazikika wa anyamata okonda kuuluka ochokera ku Iceland kupita ku West Africa, zomwe zinapereka deta yofunika kwambiri yomvetsetsa khalidwe la achinyamata okonda kusamukira.

Chithunzi: Kuyerekeza kwa njira zowulukira pakati pa mbalame zazikulu ndi zazing'ono za ku Ulaya.. kufuula kwa akuluakulu, gulu b. Ana.
