ʻO kēia mau toadstools me nā nuku pololei, nā ʻāʻī mānoanoa a me nā poʻo "square". I ka wā hānau, he ʻulaʻula ko lākou ʻāʻī a me ka ʻōpū, nā kua hina a me nā poʻo ʻeleʻele me kahi kiko melemele paʻa mai kēlā me kēia maka a i ka hope o ke poʻo. He oho hina-melemele nā manu ʻōpio, keʻokeʻo ka hapa haʻahaʻa o ke poʻo. Hinahina-ʻeleʻele nā poʻe mākua hānai ʻole me ke keʻokeʻo ma ka lalo o ke poʻo a me ka ʻāʻī.
Kahi noho
I ka hoʻoilo, ʻike ʻia ka ʻāʻī poʻo ʻulaʻula i ka wai paʻakai ma nā kahakai kahakai a me nā kahakai ākea, a ʻoi aku ka liʻiliʻi i ka wai hou. I ka wā o ka pūnana, noho i nā loko me kahi hui o nā mea kanu wai ākea a me nā wahi wai.
Kūleʻa kēia manu ma nā ʻaoʻao hānau o Eurasia a me ʻAmelika Hema. Ma loko o ka European Union, hānau wale nā laha i Skotlandia, kahi o ka heluna kanaka he 60 mau hānau hānau. ʻO ka helu nui o nā grebes ʻulaʻula ʻulaʻula o ʻEulopa i koho ʻia ma 6,000-9,000 mau pā hānau hānau ma kahakai o ke Kai ʻĀkau a ma nā loko o ʻEulopa ʻEulopa. I kekahi manawa lele ka manu i ke kai Kaiwaenahonua. ʻOiai nā fluctuations kūloko nui, kūpaʻa ka lehulehu o nā laha.
He aha ka mea e ʻai ai
I ke kauwela, hānai nā manu i nā mea kolo a me nā crustacea, i hopu ʻia i lalo o ka wai. I ka hoʻoilo, ʻai lākou i ka iʻa, crustacean, molluscs a me nā kolo.
ʻO ka pūnana o nā grebes ʻulaʻula-ʻāʻī
Kūkulu pū nā kāne a me nā wahine i kahi pūnana, kahi puʻu lana o nā mea kanu mākū i heleuma i nā mea ulu. Hoʻokomo ka wahine i ʻehā a ʻelima mau hua, a hoʻouluulu ka pālua i nā hua no 22-25 mau lā. Hānai nā mākua ʻelua i ka ʻōpio, hoʻomaka lākou e ʻauʻau ma hope koke iho o ka hānau ʻana a holo ma ke kua o ko lākou mau mākua. I ka wā o ke komo ʻana o ka toadstool ma lalo o ka wai, noho mau nā moa ma ko lākou mau kua a puka aʻe, paʻa paʻa i nā hulu. Lele nā holoholona ʻōpio ma hope o 55 a 60 mau lā o ke ola.
Ka neʻe ʻana i ka neʻe
Ke hoʻokokoke mai nei ka hoʻoilo, haʻalele nā manu i ko lākou pūnana a neʻe i ke kai kapakai a me nā loko nui. Hoʻomaka ka neʻe ʻana o ke kauwela i ka hopena o ʻAukake, me kahi piko ma ʻOkakopa-Nowemapa. Lele nā ʻāʻī ʻāʻī ʻulaʻula mai nā kahua hoʻoilo no ka pūnana ʻana ma Malaki-ʻApelila. Hiki lākou i nā wahi hoʻomoe hua manu, akā ʻaʻole kūkulu i nā pūnana a hiki i ka wā e hemo ʻole ai ka wai o ka hau.
Nā mea leʻaleʻa
ʻAi ka ʻāʻī ʻāʻī ʻulaʻula i kona hulu, ʻaʻole i ʻai ʻia, hana lākou i kapeta ma ka ʻōpū. Manaʻo ʻia ka hulu e pale i ka ʻōpū mai nā iwi ʻoi o ka iʻa i ka wā o ka digestion. Hānai nā mākua i nā holoholona ʻōpio me ka hulu.
