Gutahura akarere katari kororoka n'inzira y'ubwimukira ya Whimbrels (Numenius phaeopus rogachevae) mu nzira y'indege yo mu burasirazuba bwa Aziya-Ositaraliya.

Ubwoko (Inyoni):Whimbrel (Numenius phaeopus)

Ikinyamakuru:Ubushakashatsi ku Ngurube

Incamake:

Kumenya inzira zo kwimuka no guhuza inyoni zimuka ku rwego rw'abaturage bifasha gusobanura itandukaniro ryihariye mu kwimuka. Ubwoko butanu bw'inyoni bwamenyekanye muri Whimbrel (Numenius phaeopus) muri Eurasia. Ssp. rogachevae ni bwo bwoko bw'inyoni buherutse kuvugwa. Yororokera muri Siberiya yo Hagati, mu gihe akarere kayo katari kororokeramo n'inzira zo kwimuka bitarasobanuka neza. Twakurikiranye ukwimuka kwa Whimbrels zo muri Eurasia zafatiwe ahantu hatatu hatari kororokeramo (Moreton Bay mu burasirazuba bwa Ositaraliya, Roebuck Bay mu majyaruguru y'uburengerazuba bwa Ositaraliya na Sungei Buloh Wetland muri Singapuru) n'ahantu habiri ho kwimuka (Chongming Dongtan na Mai Po Wetland mu Bushinwa). Twasanze aho kororera no gusesengura ubwoko bw'inyoni zashyizwe mu gace ka Aziya y'Iburasirazuba - Australasian Flyway (EAAF) hashingiwe ku buryo buri bwoko bw'inyoni buzwi bukwirakwira. Mu nyoni 30 zashyizwe mu byiciro, inyoni 6 na 21 zororokeye mu bwoko bwa ssp. rogachevae na variegatus, uko zikurikirana; Imwe yororerwaga mu gace gakekwa ko gahinduka hagati y’ubwoko bw’inyoni zororerwamo za ssp. phaeopus na rogachevae, naho ebyiri zororerwaga mu karere hagati y’ubwoko bw’inyoni zororerwamo za ssp. rogachevae na variegatus. Inyoni zororerwaga mu bwoko bw’inyoni zororerwamo za ssp. rogachevae zamaze igihe cyazo cyo kororerwa mu majyaruguru ya Sumatra, Singapuru, East Java n’Amajyaruguru y’Uburengerazuba bwa Ositaraliya kandi ahanini zahagaze ku nkengero z’Ubushinwa mu gihe cyo kwimuka. Nta n'imwe mu nyoni zacu yororerwaga mu bwoko bw’inyoni zororerwamo gusa. Ubushakashatsi bwakozwe mbere bwagaragaje ko inyoni zororerwaga za rogachevae zimuka ku muhanda wa Aziya yo Hagati zikamara igihe cyo kororerwamo mu Burengerazuba bw’Ubuhinde no muri Afurika y’Iburasirazuba. Twasanze nibura zimwe mu nyoni zororerwaga za rogachevae zimuka ku muhanda wa EAAF zikamara igihe cyo kororerwamo muri Aziya y’Amajyepfo y’Uburasirazuba na Ositaraliya. Inyoni zororerwaga za ssp. phaeopus ziboneka gake cyane muri EAAF mu karere k’iburengerazuba, cyangwa se ntizibaho na gato.
