Inyamaswa zisubiza ibidukikije ku munzani utandukanye buri kimwe gisaba ingamba zitandukanye zo kubungabunga ibidukikije. Inyoni zo mu mazi ni ibintu byingenzi byerekana ibinyabuzima byo mu gishanga cyugarije isi yose ariko uburyo bwabo bwo guhitamo ahantu hatandukanye ntabwo bwakunze kwigwa. Twifashishije amakuru yo gukurikirana icyogajuru hamwe na moderi ntarengwa ya entropiya, twize uburyo bwo gutoranya aho amoko abiri y’inyoni agabanuka, Ingagi nini y’imbere y’imbere (Anser Albifrons) na Tundra Bean Goose (A. serrirostris), ku munzani itatu: ahantu nyaburanga (30, 40, 50 km), kurisha (km 10, 15, 20 km) Twakekereje ko guhitamo ahantu nyaburanga hatoranijwe hashingiwe cyane cyane ku bipimo nyaburanga bigereranijwe, mu gihe ibisobanuro birambuye by’imiterere byafashwe ingamba zo guhitamo aho gutura no gutura. Twabonye ko amoko y’inyoni y’amazi yahisemo ahantu hafite ijanisha ryinshi ry’ibishanga n’amazi ku gipimo cy’imiterere y’imiterere, amazi y’amazi akusanyirijwe hamwe n’ibihingwa bitatanye ku gipimo cy’ibihingwa, hamwe n’ibishanga bihujwe neza hamwe n’amazi meza hagati y’amazi meza ku gipimo cyo koroha. Itandukaniro nyamukuru mu guhitamo aho amoko yombi yabereye ahantu nyaburanga no kurisha; ibintu ku gipimo cyo guswera byari bisa. Turasaba ko ibikorwa byo kubungabunga ibidukikije bigomba kwibanda ku kuzamura igiterane n’umuhuza w’amazi n’ibishanga, no guteza imbere ubutaka bw’ibihingwa bidakusanyirijwe hamwe. Uburyo bwacu bushobora kuyobora uburyo bwo kubungabunga inyoni zo mu mazi no gucunga ibishanga dutanga ingamba zifatika zo kuzamura ireme ry’imiturire imbere y’imihindagurikire y’ibidukikije iterwa n’abantu.
