Mu byo bagaragaje harimo ko ubutinganyi mu nyamaswa bushobora guturuka ku mpamvu zitandukanye zirimo no kuba inyamaswa z’igitsina kimwe zimarana igihe kinini aho ziba, ubuke bw’inyamaswa ngenzi zazo z’igitsina runaka ndetse n’ibindi.

Aha batanze urugero rw’inyoni zo mu bwoko bwa ‘Roseate Tern’, aho muri zo usanga iz’igitsinagabo ari nke cyane ugereranyije n’iz’igitsinagore, ku buryo usanga byoroshye ko iz’igitsinagore zitingana cyangwa se izitabikoze ugasanga zororoka ari nyinshi bigizwemo uruhare n’iy’igitsinagabo imwe.
