Grebe nto
Grebe ntoya,cyangwa se dabchick, ni umwe mu bagize umuryango wa grebe w'inyoni zo mu mazi . Izina ryubwoko ryakomotse kuri takhus ya kera yikigereki "yihuta" ikaba ikomoka, mu kilatini " ijosi ". 

iyi nyoni ikaba arimwe muzigize umuryango muto wo mu Burayi mu muryango wacyo. Bikunze kuboneka mumazi afunguye hafi yuburinganire bwayo.

Amatagisi 
Grebe ntoya yasobanuwe numudage Peter Simon Pallas mu 1764 ahabwa izina rya binomial Colymbus ruficollis .    Grebe ya tricolored yabonwaga ko idasobanutse,bamwe mu bayobozi bashinzwe ibidukikije

ntibarasobanukirwa neza.

Grebe akaba ari inyoni nto ikunda kuboneka mumazi cyane,yiganjemo umwijima hejuru hamwe nijosi ryayo, rinini, ijosi n'impande, hamwe n'umuhondo wera. Rufous isimburwa nicyatsi cyijimye cyijimye cyinyoni zitororoka ninyoni.

Greb ikaba ari inyoni ifite ibara ry'umukara n'umweru byera ku matama no ku mpande z'ijosi nkuko bigaragara hepfo.

Ikwirakwizwa 
Iyi nyoni yororoka muri koloni ntoya mu bimera byinshi by’ibiyaga by’amazi meza mu Burayi. Inyoni nyinshi zimukira mumazi menshi yuguruye cyangwa yinyanja mugihe cyitumba, ariko irimuka gusa muribice bigize aho amazi akonja. Hanze yigihe cyubworozi, yimukira mumazi afunguye, rimwe na rimwe akanagaragara ku nkombe mu biyaga bito.

Imyitwarire 
Grebe ntoya ni inyoni nziza kandi ikayobora kandi ikurikirana amafi yayo ninyamaswa zo mu mazi zidafite ubuzima. Ikoresha ibimera ubuhanga nkahantu hihishe.

Kimwe na grebes zose, ziba ku nkombe y'amazi, kubera ko amaguru yayo yashizwe inyuma cyane kandi ntashobora kugenda neza. Ubusanzwe itera amagi 4-7. Iyo inyoni ikuze ivuye mucyari mubisanzwe yitondera gupfuka amagi. Ibi bituma bidashoboka kumenyekana ninyamanswa.  Abakiri bato bava mucyari kandi bashobora koga nyuma yo kubyara. Mu Buhinde, ubwoko bwororoka mu gihe cy'imvura.
