ʻO ka ʻāpala ʻeleʻele ʻAmelika (Anas rubripes) a i ʻole ke kūʻai ʻeleʻele ʻAmelika no ka ʻohana duck, ke kauoha Anseriformes.
ʻO ka hoʻolaha ʻana o ka ʻehu ʻeleʻele ʻAmelika
He ʻōiwi ʻōiwi ʻAmelika ia ma ka hikina hikina o Manitoba, Minnesota. Holo ka nohona ma ka hikina ma waena o nā mokuʻāina ʻo Wisconsin, ʻIlika, ʻAmelika, Pennsylvania, Maryland, West Virginia, Virginia. Pākuʻi ʻia i nā wahi ululāʻau o Eastern Canada ma Northern Quebec a me Northern Labrador. ʻO kēia ʻāpana pato i nā wahi hema o kona laulā a ma ka hema i ke Kai Kūʻono, Florida a me Bermuda.
ʻO kahi noho pākeke ʻeleʻele ʻAmelika
Makemake ka pālule ʻeleʻele ʻAmelika e noho i nā ʻano ʻano wai wai hou a paʻa hoʻi aia ma waena o nā ululāʻau. Noho ʻo ia i loko o nā wahi kai me nā wahi acidic a me alkaline, a me nā loko, nā loko a me nā auwai kokoke i ka māla. Hoʻolahalaha ʻia i nā kai kūʻono a me nā estuaries. Makemake ia i nā wahi ʻoluʻolu meaʻai, e hoʻopili ana i nā awāwa brackish estuarine me nā ʻāina mahiʻai e pili kokoke ana.
Ma waho o ka wā hānau, ʻākoakoa nā manu ma nā kahawai nui hāmama, ma kahakai, a ma nā kai kiʻekiʻe hoʻi. ʻO nā ʻelele ʻeleʻele ʻAmelika kahi i neʻe hapa aku. Noho kekahi mau manu ma ke Kai Kūʻono Nui a puni ka makahiki.
I ka wā hoʻoilo, neʻe ka hapa nui o ka ʻākau o ka ʻūlū ʻeleʻele ʻAmelika i lalo i nā latitude ma ke kahakai ʻAkelanika o ʻAkau ʻAmelika a neʻe i ka hema i Texas. ʻIke ʻia kekahi mau kānaka ma Pokoliko, Kōlea a me ʻEulopa Komohana, kahi e loaʻa ai i kekahi o lākou kahi noho mau no nā wā lōʻihi.
Nā hōʻailona kūwaho o ka ʻehu ʻeleʻele ʻAmelika
ʻO ka peʻa ʻeleʻele ʻAmelika i ka hānai hānau ʻana he mau wahi ma ke poʻo me nā uaua ikaika o ka ʻeleʻele, keu hoʻi ma nā maka, a ma ka lei o ke poʻo. ʻO ka ʻaoʻao luna o ke kino, me ka huelo a me nā ʻeheu, ʻeleʻele-ʻeleʻele i ke kala.
ʻO nā hulu o lalo he ʻeleʻele, ʻeleʻele - ʻeleʻele me nā ʻulaʻula ʻulaʻula a me nā pā. Loaʻa i nā hulu lele ʻelua he "aniani" iridescent polū me ka ʻāpana ʻeleʻele ma ka palena a me kahi kiko keʻokeʻo keʻokeʻo. He aniani, ʻeleʻele nā hulu lele tertiary, akā ʻo ke koena o ka plumage ʻeleʻele hina a ʻeleʻele ʻeleʻele, a keʻokeʻo silvery keʻokeʻo.
ʻEleʻele ka iris o ka maka.
ʻO ka nuku he ʻōmaʻomaʻo-melemele a melemele ʻōlinolino paha, me nā marigold ʻeleʻele. ʻAlani-ʻulaʻula nā wāwae. He ʻōmaʻomaʻo ʻōmaʻomaʻo a ʻoliva hoʻi ka nuku o ka wahine me kahi kiko ʻeleʻele iki. ʻO nā wāwae a me nā wāwae he brown-ʻoliva.
ʻO ke kala o ka plumage o nā manu ʻōpio e like me ka plumage o nā mākua, akā ʻokoʻa i nā kiko, nā wahi lōʻihi lōʻihi i ka umauma a ma lalo o ke kino. He ākea nā kihi o ka hulu, akā ʻoi aku ka pouli ma mua o nā ʻōlelo aʻoaʻo. I ka lele ʻana, ua like ka ʻūlū ʻeleʻele ʻAmelika me he mallard lā. Akā ʻeleʻele ke nānā aku, ʻaneʻane ʻeleʻele, ʻoi aku ke kū i waho o nā ʻeheu, ʻokoʻa ia i ke koena o nā plumage.
Pālua ʻEleʻele Duck
Hoʻomaka ka hānau ʻana i nā ʻāpō ʻeleʻele ʻAmelika i Malaki-ʻApelila. Hoʻi pinepine nā manu i kā lākou mau pūnaewele paʻa mua, a pinepine pinepine wau e hoʻohana i nā hale hoʻopaʻa kahiko a i ʻole hoʻonohonoho i kahi pūnana hou 100 mau mika mai ka hale kahiko. Aia ka pūnana ma ka honua a hūnā ʻia ia ma waena o nā mea kanu, i kekahi manawa i loko o ka lua a i ʻole ke ākea ma waena o nā pōhaku.
ʻO Clutch he 6-10 mau ʻōmaʻomaʻo - nā hua melemele.
Hoʻokomo ʻia lākou i ka pūnana ma nā manawa o hoʻokahi i kēlā me kēia lā. ʻOi aku ka liʻiliʻi o nā hua manu i nā wahine ʻōpio. I loko o ka wā incubation, noho ke kāne kokoke i ka pūnana no kahi o 2 mau pule. Akā ʻaʻole i hoʻokumu ʻia kona komo ʻana i ka hānau hānau. Hoʻokū ʻia ka hoʻouluulu ma kahi o 27 mau lā. ʻO ka manawa pinepine, hāʻule nā hua a me nā moa i nā ʻakaʻaka a me nā lono. Hōʻike nā hua mua i ka mua o Mei, a hatching peaks i ka mua o Iune. Hiki i nā ʻāpō wahine ke ukali i ka ʻāpō i nā hola 1-3. Alakaʻi ka wahine i kāna keiki no 6-7 mau pule.
Nā hiʻohiʻona o ke ʻano o ka ʻūlū ʻeleʻele ʻAmelika
Ma waho o ka wā lūlū, manu manu ʻoluʻolu loa nā ʻeleʻele ʻAmelika. I ke kauwela a me ka puna, hana lākou i nā hipa he hoʻokahi tausani a ʻoi paha manu. Eia nō naʻe, i ka hopena o Kepakemapa, hoʻokumu ʻia nā pālua, lahilahi ka ʻohana a emi iki hoʻi. Hoʻokumu ʻia nā pālua no ka wā hānau a ola no kekahi mau mahina. Kū ka piko o nā pilina hoʻomāinoino i ka waena o ka hoʻoilo, a i ʻApelila, kokoke i nā wahine a pau ka pilina i loko o ka pālua.
ʻAi pā ʻeleʻele ʻAmelika
ʻAi nā ʻāpala ʻAmelika i nā ʻanoʻano a me nā mea kanu o nā mea kanu wai. I ka papaʻai, hana nā invertebrates i kahi mahele kiʻekiʻe.
- nā kolo,
- pūpū,
- crustaceans, keu hoʻi i ka puna a me ke kauwela.
ʻAi nā manu i ka wai pāpaʻu, e mākaʻikaʻi mau i ka papa lepo me ko lākou nuku, a i ʻole huli i ke alo e hoʻāʻo nei i kā lākou mea pio. Luu lākou i kekahi manawa.
Duck ʻEleʻele ʻAmelika - Pahuhopu o ka pāʻani
He mea nui ka American Black Duck i kahi huli holoholona waikaʻu ma ʻAkau ʻAkau no ka manawa lōʻihi.
ʻO ke kūlana mālama o ka ʻūlū ʻeleʻele ʻAmelika
ʻO ka helu o nā ʻeke ʻeleʻele ʻAmelika i nā makahiki 1950 ma kahi o 2 miliona, akā ʻo ka nui o nā manu e emi mau nei mai kēlā manawa. I kēia manawa, ma kahi o 50,000 e noho nei i ke kūlohelohe. ʻAʻole ʻike ʻia nā kumu o ka emi ʻana o nā helu, akā no ka nalowale ʻana o nā wahi noho, ka maikaʻi ʻole o ka wai a me ka maikaʻi o ka meaʻai, ka hahai holoholona ikaika, ka hoʻokūkū me nā ʻano pākī ʻē aʻe a me nā hybridization me nā mallard.
ʻO ka hiʻohiʻona o nā kānaka hapalua e hana i kekahi mau pilikia no ka hana hou ʻana o nā laha a alakaʻi i kahi hōʻemi o ka helu o ka ʻāpala ʻeleʻele ʻAmelika.
ʻAʻole hiki ke ola nui nā wahine Hybrid, kahi e hopena ai i ka hānau ʻana o nā keiki. ʻAʻohe ʻokoʻa ka Hybrids mai nā manu non-hybrid, a eia hou, ua hōʻike ʻia nā noiʻi ʻana e make pinepine nā wahine hybrids ma mua o ko lākou manawa hānau. ʻIke akāka ʻia kēia ma nā hihia o nā keʻa interspecific mai ka ʻeleʻele ʻAmelika i ka mallard.
Ma ke ʻano he hopena o ke koho kūlohelohe, ua hoʻomohala ʻia nā mallard lehulehu i nā ʻano adaptive stable i nā kūlana kaiapuni. No laila, ʻike ka hapa liʻiliʻi o ka American Black Duck i nā mana kūlohelohe. I kēia manawa, he mea nui e hōʻalo i nā kuhi hewa i ka ʻike ʻano.
