Pāpale kani a i ʻole ʻāpō kani (Aythya collaris) no ka ʻohana duck, kauoha ʻo anseriformes.
Hoʻolahalaha o ka luʻu kani.
ʻO Ringed Duck kahi ʻano neʻe i ka nui. I ka wā hānau, pālahalaha loa ia i ka ʻākau o ka Hema a me Central Alaska. Hoʻopili ka laulā i nā wahi o Central Canada, a me Minnesota, Maine, a me nā ʻāpana o ka ʻākau o ʻAmelika Hui Pū ʻIa. I nā wahi he nui, e like me nā mokuʻāina ʻo Wakinekona, Idaho, a me nā mokuʻāina komohana ʻē aʻe o ʻAmelika Hui Pū ʻIa, ola ke ʻāpō kani i ka makahiki holoʻokoʻa. Hānau pinepine kēia ʻano ma ka ʻākau ʻo Alberta, Saskatchewan, Minnesota, Wisconsin, Michigan, ma Manitoba waena, a ma ka hema o Ontario a me Quebec.
ʻO ka nohona o ka luʻu kani.
ʻO ka nohona o ka ʻāpō kani e loli me ke kau. I ka wā hānau a ma hope o ka wā hānau, makemake ʻo ia i nā wahi wai wai, nā wahi pāpaʻu haʻahaʻa haʻahaʻa haʻahaʻa. I ka hoʻoilo, neʻe nā luʻu apo i loko o nā mākā nui, akā ʻaʻole loaʻa iki i nā wahi me ka paʻakai kiʻekiʻe a me ka hohonu> 1.5 mau mika. ʻO nā kahawai Floodplains o nā kahawai, nā wahi hou a paʻa hoʻi o nā estuaries, a me nā loko wai paʻa a me nā kahawai i paʻa mau i kēia ʻano. ʻIke ʻia nā pēpē kani i nā wahi pāpaʻu me nā lepo momona i uhi ʻia me nā mea kanu, i nā ʻāina mahiʻai i hoʻopiha ʻia, i nā loko iʻa.

ʻO Duck Duck kahi pato liʻiliʻi. ʻOi aku ka nui o ke kāne ma mua o ka wahine. Lōʻihi ke kino o ke kāne ma waena o 40 a 46 cm, a ʻo ka wahine - 39 - 43 knm. ʻO ke kaupaona o ke kāne 542 - 910 g, a ʻo ka wahine - 490 a me 894 g. 63.5 cm ka ʻūheu.
He poʻoʻeleʻele ko ka kāne, ʻāʻī, umauma a me ke kino kiʻekiʻe. ʻO ka ʻōpū a me nā ʻaoʻao he keʻokeʻo-hina. Ma ka ʻēheu pelu, ʻike maopopo ʻia kahi ʻū keʻokeʻo ma ka poʻohiwi, e piʻi aʻe i luna. Hinahina oho hina ka wahine me nā kaha ʻeleʻele ma ka piko o ke poʻo. ʻO ka mua o ke poʻo, ka aʻa, a me ka puʻu he paler maʻamau. Hoʻopuni ʻia nā maka e ke apo keʻokeʻo, ma ka laulā, ʻoi aku ka haʻahaʻa o ka plumage o ka wahine ma mua o ke kāne. He silhouette ko ka pālule kani e like me nā ʻāpō luʻu ʻē aʻe, akā he lōʻihi kona lōʻihi o ka huelo a me kahi poʻo me kahi kualapa pōkole, a hāʻawi iā ia i kahi ʻano kikoʻi a kihi paha. ʻAno like nā manu ʻōpio me nā ʻāpō makua, akā he ʻōuli pulu ko lākou.
ʻO ka hana hou ʻana o ka luʻu kani.
ʻO Ringed Duck kahi ʻano monogamous, hana ʻia nā pālua i ka neʻe ʻana o ka pūnāwai, mai Malaki a ʻApelila. Kū ka wā hānau mai Mei a hiki i ʻAukake, me ka hana piko mai ka waena o Mei a waena o Iulai.
Hōʻike ʻia ka hana mākia i ka neʻe ʻana o ke kino, ʻoiai e luʻu ikaika ana ka luʻu i ka ʻāʻī, hāpai i kona poʻo i luna a pahu i kona nuku i mua. Hana ʻia kēia hōʻike ma ka ʻāina a ma ka wai. A laila hoʻohaʻahaʻa ʻia ka nuku i loko o ka wai me ka ʻole o ke poʻo, a ma hope o ka moʻo ʻana, ʻauʻau nā manu ʻelua i kekahi ʻaoʻao a kiʻekiʻe ke poʻo.
Ke koho ʻana i kahi kahua pūnana, ʻauʻau kekahi manu ʻelua i ka wai ākea o kahi wai pulu.
Koho ka wahine i kahi kūpono kūpono ʻoiai ke kāne e noho kokoke ana. ʻIke ka pato i kahi maloʻo a maloʻo paha kokoke i ka wai, pinepine me nā mānoanoa o nā mea kanu. Kūkulu ka wahine i ka pūnana no 3 - 4 lā. Ua like ia me kahi pola, a ma ka lā 6 e ʻikea ke ʻano mōakāka. ʻO ka mauʻu, lalo, hulu nā mea kūkulu.
Hoʻomoe ka wahine he 6 a 14 mau hua i kēlā me kēia kau. ʻO nā hua he oval i ke ʻano me kahi ʻoluʻolu, ʻokoʻa ke kala o ka pūpū i ke kala: ʻoliva hina i ka ʻoliva brown. Hoʻomaka ka Incubation ma hope o ka paʻa ʻana o ka paʻa a paʻa mau i nā lā he 26 a 27 paha.
Hānau ʻia nā Chicks mai ke 28 a 31 g. Uhi ʻia lākou i lalo a hiki ke hāhai i nā mākua a hānai iā lākou iho ma hope koke o ka hoʻomaloʻo ʻana. Holo ʻo Ducklings ma hope o 49 a 56 mau lā a kūʻokoʻa i 21 a 56 mau lā ma hope o ka heʻe ʻana. Hānau ka poʻe ʻōpio ʻōpio i ka makahiki mua.
Noho ka luʻu lipe i ke kūlohelohe no 20 mau makahiki.
Nā hiʻohiʻona o ka lawena o ka luʻu kani.
ʻO nā luʻu kuni ke neʻe mau, lele, lele, ʻauʻau, a luʻu paha. Puka lākou mai ka wai a kū i luna o nā mea lana i ka wā hoʻomaha. Wikiwiki ka lele o kēia ʻano pato. Piʻi koke ka ʻohana he iwakālua mau kānaka i ka lewa a lele i kahi puʻu paʻa. Hiki i nā Duck ke luʻu i ka hohonu o ʻumi mau mika e hoʻohana nei i ka neʻe ʻana o ka wāwae. Hoʻomaʻemaʻe mau nā luʻu kani i nā hulu, e kīloi ana i ko lākou mau wāwae a me ka ʻauʻau ʻana. Ke hoʻomaha a lulu paha ka lā, noho lākou i ka mālie, ka wai hāmama, i nā wahi i pale ʻia e ka makani.
ʻAʻohe mea hōʻike i ka territoriality o kēia ʻano, akā i ka wai hāmama e pale ke kāne i ka hakahaka me kahi radius ma kahi o 2 - 3 mau mika a puni ka wahine. ʻAʻole loaʻa i nā mea ʻoni āpau āpau ke loaʻa i kahi hoa ma muli o ka ʻaihue ʻana i ka lakene moekolohe, ʻo ka maʻamau he nui nā kāne ma mua o nā wahine a ʻo kēia lakio he 1.6: 1. No laila, noho mehameha kekahi mau kāne a hana i nā hui liʻiliʻi o 6 a ʻoi paha mau mea liʻiliʻi. Ma waho o ka wā lūlū, mālama ʻia nā luʻu kani i nā pūʻā a hiki i 40 mau manu. I ka wā o ka neʻe a me ka hoʻoilo, ke nui ka meaʻai, hiki i nā hipa ke helu i nā kānaka he 10,000.
E ʻai ana ka luʻu lū.
Hānai nui nā luʻu lūlū i nā ʻano mea kanu a me nā paipu, a ʻai i nā invertebrates wai. I kekahi manawa hopu ʻia nā pepelu. ʻAi nā pēpē makua i nā ʻano mea kanu wai, ʻai i ka pondweed, nā līlia wai, a me nā hornwort.

Makemake lākou i ka ʻai pāpaʻu o ka wai, ʻoiai hiki iā lākou ke luʻu, hiki i ka lalo, waiwai i nā ʻōpala ʻokanika. ʻO nā Duck, ma ke ʻano he rula, e kiʻi i ka meaʻai i ka wā e bapetizo ʻia ai i ka wai, akā lawe ʻia ka mea pio i ka ʻili i mea e loaʻa ai ke kino o nā mollusks mai ka pūpū a i ʻole e wehe i ka chitin mai ke kino o ka kolo.
Loaʻa nā nui o ka prey mai ka 0.1 mm a i ka 5 cm. ʻAi nā Ducklings i nā invertebrates, kahi e 98% o ka nui o ka papaʻai. Mālama nā wahine i ka ʻai i nā invertebrates ma mua o ka wā maʻamau i ka wā hānau, ke koi ʻia nā protein protein e hoʻomoe i nā hua. ʻO ka pio nui no nā pēpē annelid ʻo nā ilo, nāʻe, nā mollusc, nā dragonflies a me nā lele caddis.
