Vorona

Ny vorona dia zavamananaina ao amin' ny zana-pisampanan' ny Vertebrata (biby manana hazondamosina), izay mamorona ny kilasy Aves. Mafana ra sady manatody izy ireo. Rakotra volom-borona ny tenany sady manana rantsam-batana ambany roa sy elatra roa ary tsy misy nify. Misahana anjara asa telo ny volom-borona: ny fisidinana sy ny fifehezana ny mari-pana ary ny fisehoana. Poaka aty ny taolan' ny vorona ka izany no mampaivana ny lanjany. Mafana vatana izy ireo ka mampiasa hery betsaka. Noho izany dia mihinana sakafo be dia be izy ireo raha oharina amin' ny lanjany. Karazam-borona samihafa mihoatra ny 9 000 no efa fantatra.

Hita ao amin' ny kôntinenta rehetra eto amin' izao tontolo izao ny vorona. Afaka miaina amin' ny tontolo mangatsiaka ny karazam-borona samihafa, ary misy ny afaka miaina amin' ny toetany mafana. Hita any anaty ala, eny amin' ny kijana, eny amin' ny harambato, eny amin' ny moron-drenirano, eny amin' ny vato amoron-dranomasina, eny amin' ny tampon-tranon' olona ny vorona.vignette|Vorona|302x302pxMihinana sakafo isan-karazany ny vorona. Mihinan-kena ny ankamaroany. Maro ny mihinana bibikely na trondro. Mihinana karazam-bibilava na voalavo na koa karazam-borona hafa ny sasany. Misy koa ny vorona mihinana fatim-biby. Ny vorona toa ny boloky dia mihinana voamadinika sy voankazo.
