Inzira zo kwimuka buri mwaka, uburyo bwo guhagarara hamwe n'ibikorwa bya buri munsi by'inyoni zo mu bwoko bwa Eurasian Bitterns Botaurus stellaris mu gihe cy'itumba mu Bushinwa.

Ubwoko (Inyoni):Bittern yo muri Eurasian (Botaurus stellaris)

Incamake:

Inyoni zo mu bwoko bwa Eurasian Bitterns Botaurus stellaris zafashwe mu gihe cy'itumba mu burasirazuba bw'Ubushinwa zigwa mu Burasirazuba bwa kure bw'Uburusiya. Kugira ngo tumenye igihe cyo kwimuka, igihe n'inzira, ndetse n'ahantu ho guhagarara, byakoreshejwe na Eurasian Bitterns mu nzira y'indege yo mu Burasirazuba bwa kure bw'Uburusiya no kubona amakuru y'ibanze ku myitwarire n'ibidukikije dukoresheje amakuru akurikira. Twakurikiranye inyoni ebyiri zo mu bwoko bwa Eurasian Bitterns zafashwe mu Bushinwa zifite sisitemu yo gushyira imiterere y'isi/itumanaho rya telefoni mu gihe cy'umwaka umwe n'imyaka itatu, kugira ngo tumenye inzira zazo zo kwimuka n'ingengabihe yazo. Twakoresheje intera yavuye hagati y'impinduka zikurikiranye kugira ngo tumenye imiterere y'ibikorwa byazo bya buri munsi. Izo nyoni zombi zamaze igihe cy'itumba mu Bushinwa bw'Ubushinwa kandi zigenda impuzandengo ya kilometero 4221 ± 603 (mu 2015-17) na kilometero 3844 (2017) kugeza mu mpeshyi mu Burasirazuba bwa kure bw'Uburusiya. Ibisubizo byavuye mu nyoni imwe byagaragaje ko mu myaka itatu yose, inyoni yakoraga cyane ku manywa kurusha nijoro, nubwo itandukaniro rikomeye ryatandukanaga bitewe n'ibihe, ikaba ikora cyane nijoro mu mpeshyi. Umusaruro utangaje cyane wavuye muri iyi nyoni ni uko yashoboraga kwimuka mu mpeshyi no kutagira ubwiza bw'ahantu ho mu mpeshyi. Ubushakashatsi bwagaragaje inzira zitari zizwi zo kwimukiramo z’inyoni zo mu bwoko bwa Eurasian Bittern muri Aziya y’Iburasirazuba, kandi bwerekanye ko muri rusange ubwo bwoko bukunda kwimuka cyane ku manywa mu gihe cy’umwaka wose.
