Kuzindikira dera lomwe silikuswana ndi njira yosamutsira mbalame za Whimbrels (Numenius phaeopus rogachevae) ku East Asian-Australasian Flyway.

Mitundu (ya mbalame):Whimbrel (Numenius phaeopus)

Magazini:Kafukufuku wa Mbalame

Chidule:

Kudziwa njira zosamukira ndi kulumikizana kwa mbalame zosamukira pamlingo wa anthu kumathandiza kufotokoza kusiyana kwa mitundu yosiyanasiyana ya mbalame zosamukira. Mitundu isanu ya mbalame yadziwika ku Whimbrel (Numenius phaeopus) ku Eurasia. Ssp. rogachevae ndi mtundu wa mbalame zomwe zafotokozedwa posachedwa. Imabereka ku Central Siberia, pomwe chigawo chake chosaberekera ndi njira zosamukira sizikudziwikabe. Tinatsata kusamuka kwa mbalame za ku Eurasian Whimbrels zomwe zinagwidwa m'malo atatu osaberekera (Moreton Bay kum'mawa kwa Australia, Roebuck Bay kumpoto chakumadzulo kwa Australia ndi Sungei Buloh Wetland ku Singapore) ndi malo awiri oimikapo mbalame (Chongming Dongtan ndi Mai Po Wetland ku China). Tinapeza malo oberekera ndipo tinapeza mitundu ya mbalame zomwe zatchulidwa ku East Asia - Australasian Flyway (EAAF) kutengera kufalikira kodziwika kwa mitundu iliyonse ya mbalame. Mwa mbalame 30 zomwe zatchulidwa, mbalame 6 ndi 21 zinaberekera m'gulu la ssp. rogachevae ndi variegatus, motsatana; Mbalame imodzi inaberekedwa m'dera lomwe limaganiziridwa kuti ndi losinthasintha pakati pa mitundu yoberekera ya ssp. phaeopus ndi rogachevae, ndipo ziwiri zinaberekedwa m'derali pakati pa mitundu yoberekera ya ssp. rogachevae ndi variegatus. Mbalame zomwe zinaberekedwa m'gulu loberekera la ssp. rogachevae zinakhala nyengo yawo yosaberekera kumpoto kwa Sumatra, Singapore, East Java ndi Northwest Australia ndipo makamaka zinaima m'mphepete mwa nyanja ya China panthawi yosamukira. Palibe mbalame zathu zomwe zinaberekedwa m'gulu loberekera la phaeopus subspecies. Kafukufuku wakale adaneneratu kuti mbalame za rogachevae whimbrels zimasamukira m'mphepete mwa Central Asian Flyway ndipo zimakhala nyengo yosaberekera ku West India ndi East Africa. Tapeza kuti mbalame zina za rogachevae whimbrels zimasamukira m'mphepete mwa EAAF ndipo zimakhala nyengo yosaberekera ku Southeast Asia ndi Australia. Mbalame za ssp. phaeopus sizimapezeka kwambiri m'chigawo chakumadzulo kwa Asia, kapena mwina sizimapezeka konse.
