Ibikona ntibikurikira amasega: ubushakashatsi bwerekanye ko byibuka aho asanzwe yica
Abahanga bemeraga ko ibikona bikurikira amasega ngo bibone ibisigazwa by’inyamaswa yishe. Ubushakashatsi bwo mu kinyamakuru Science bwerekanye ko atari ko bimeze.
Mu myaka myinshi abahanga bemeraga ko ikintu kimwe gisobanura impamvu ibikona bihita bigera aho isega rimaze kwica inyamaswa: bivugwaga ko biba bikurikiye ayo masega. Ubushakashatsi bwasohotse mu kinyamakuru Science ku wa 12 Werurwe 2026 bwerekanye ko iyo nyigisho itari yo.
Imyaka ibiri n’igice bakurikirana ibikona 69
Itsinda ry’abashakashatsi riyobowe n’ikigo cy’ubushakashatsi ku binyabuzima byo mu gasozi cya Kaminuza y’ubuvuzi bw’amatungo i Vienne mu Butiriya, rifatanyije n’Ikigo cya Max Planck gishinzwe imyitwarire y’inyamaswa mu Budage, ryashyize ibyuma bya GPS ku bikona 69, rikurikirana kandi amasega 20 yari yambitswe imikandara ikurikiranwa. Ibyo byakorewe muri parike ya Yellowstone muri Amerika mu gihe cy’imyaka ibiri n’igice.
Inshuro imwe gusa mu myaka ibiri n’igice
Mu gihe cyose cy’ubwo bushakashatsi, abashakashatsi babonye inshuro imwe gusa aho igikona cyakurikiye isega urugendo rurenga kilometero imwe cyangwa igihe kirenga isaha. Ibisigaye byose byerekana ko ibikona bitegera aho inyamaswa yiciwe atari uko biba byitegereje isega.
Ikarita bafite mu mutwe
Ahubwo ibikona byagendaga bisubira mu duce twagaragaye ko amasega akunze kwicamo inyamaswa, aho kujya ahandi. Bimwe byagendaga kugeza kuri kilometero 155 ku munsi umwe byerekeza kuri utwo duce.
Ibi bisobanura ko ibikona bishobora kwibuka ahantu hanini cyane mu gihe kirekire, bikigira nk’ikarita yo mu mutwe y’aho ibiryo bikunze kuboneka, aho kwiringira gukurikira isega imbona nkubone.
Matthias-Claudio Loretto, umwanditsi wa mbere w’ubwo bushakashatsi, yavuze mu Cyongereza ati: “They can fly six hours non-stop, straight to a kill site.” Ni ukuvuga ko bishobora kuguruka amasaha atandatu bidahagaze, byerekeza aho inyamaswa yiciwe.
Icyo bihindura
John M. Marzluff wo muri Kaminuza ya Washington, umwe mu banditsi bakuru b’ubwo bushakashatsi, yavuze ati: “This changes how we think about how scavengers find food—and suggests we may have underestimated some species.” Ni ukuvuga ko ibi bihindura uko dutekereza ku buryo inyoni zirya ibisigazwa zibona ibiryo, kandi bikerekana ko hari amoko twashoboraga kuba twarasuzuguye.
