No ka ʻohana duck ka pālū pālū ʻulaʻula, ke kauoha ʻo Anseriformes.
Nā hōʻailona kūwaho o kahi ʻāʻī pālū ʻulaʻula
Hiki i ka ʻāpala i hāʻawi ʻia i ka ʻulaʻula mai 43 a 48 cm.
ʻEleʻele ka plumage me nā kaha keʻokeʻo i ke ʻano o nā niho ma ka lihi o ka hulu. Ma ke poʻo he pāpale ʻeleʻele, ka nape o ke kala like, e hoʻohālikelike ana me ka plumage māmā o ka maka. ʻUlaʻula ʻulaʻula ka nuku. I ka wā e lele ai, ʻike ʻia nā hulu lele ʻelua o kahi ʻōniʻoniʻo melemele me kahi ʻāpana ʻeleʻele transverse ma waena o lākou. ʻO ke kala o ka uhi hulu o ka wahine a me ke kāne like. ʻO nā duck ʻulaʻula i hoʻoili ʻia i ka ʻula he paler plumage ma mua o nā manu makua.
Pāhola ʻia ka ʻāʻī Red-bil
ʻIke ʻia ka peʻa ʻulaʻula i ka hikina a me ka hema o ʻApelika. Nui ka laulā o kēia ʻano, e like me Angola, Botswana, Burundi, Kongo, Djibouti, Eritrea. Noho ma ʻAitiopa, Kenya, Lesotho, Malawi, Mozambique, Namibia. Loaʻa ma Rwanda, Somalia, Sudan Hema, Swaziland, Tanzania. Hoʻolaha ʻia ma Uganda, Zambia, Zimbabwe, Madagascar.
Nā hiʻohiʻona o ka hana a ka ʻūlū pālū ʻulaʻula
ʻO nā ʻikena i hoʻoili ʻia i ka ʻulaʻula he noho maʻa a i ʻole nomadic, akā hiki ke lele i kahi mamao, e uhi ana a i ka 1800 km i ke kau maloʻo. Ua loaʻa nā manu i hoʻopaʻa ʻia ma ʻApelika Hema ma Namibia, Angola, Zambia a me Mozambique. ʻO nā pēpē ʻulaʻula ka nohona a me nā ʻano kū i waho i ka wā o ka moʻo ʻana, a i ka hopena o ke kau maloʻo a i ke kau ua mua. Hana lākou i nā huhui nui, kahi e piʻi ai ka nui o nā manu i kekahi mau tausani mau kānaka. Ua manaʻo ʻia hoʻokahi ʻohana ma 500,000 a ua ʻike ʻia ma Lake Ngami ma Botswana.
I ke kau maloʻo, hele nā manu makua i kahi wā molting o 24 - 28 mau lā a ʻaʻole hiki ke piʻi i ka ʻēheu.
I loko o kēia manawa, nui nā ʻikena i hāʻawi ʻia i ka ʻulaʻula i ka pō i ka wā ua. Hānai lākou i ka wai pāpaʻu, e ʻohiʻohi i nā kahakai i loko o ke ao a ʻau i waena o nā mea kanu wai i ka pō.
Kahi noho ʻāpala i hoʻoili ʻia me ka ʻulaʻula
ʻOi aku nā ʻinikū Red-bilhed i nā biotopes pāpaʻu papau me ka nui o nā mea kanu o ka wai hohonu a me ka wai pāpaʻu. ʻO nā wahi noho kūpono i loko o nā loko, nā kahawai, nā kahawai liʻiliʻi, nā loko iʻa i hoʻopaʻa ʻia e nā wai mahiʻai. Noho lākou i loko o nā loko iʻa a me nā māla i hoʻopiha ʻia no kekahi manawa. ʻIke ʻia kēia ʻano pato ma ka ʻāina i ka laiki a i ʻole nā mea kanu ʻē aʻe, keu hoʻi i nā māla ʻōpala kahi e waiho mau ai nā hua kanu ʻole.
I ka wā maloʻo, hānai mau nā ʻāʻī ulaʻula i nā helu liʻiliʻi i nā wahi heleleʻi, maloʻo, manawa pōkole i nā wahi semi-maloʻo, ʻoiai naʻe i kēlā manawa ke hele nei lākou i ke kaʻina hana a noho nui i nā wai hāmama nui i nā mea ulu e ulu nei.
E hanai ana i ka ʻāpala hoʻomāʻulaʻula ʻia
ʻAi nā ʻāpala ʻulaʻula i nā mea kanu wai a i ʻole nā mahina ʻai ʻōpala i ka hapa nui o ke ahiahi a i ʻole ka pō.
ʻO kēia ʻano pato he omnivorous. ʻAi lākou:
- nā hua o nā mea kanu mahiʻai, nā ʻanoʻano, nā hua, nā aʻa, nā rhizome a me nā koʻokoʻo o nā mea kanu wai, ʻoi aku i nā sedges;
- ka wai molluscs, nā ʻeleka (ka nui o nā beetles), nā crustacea, nā ilo, nā ʻenuhe a me nā iʻa liʻiliʻi.
Ma ʻApelika Hema, i ka wā hānau, ʻai nā manu i nā ʻanoʻano o nā mea kanu terrestrial (millet, sorghum) i kāwili ʻia me kekahi mau invertebrates.
Pālaka ʻulaʻula i hoʻoulu ʻia
Mālama nā ʻāpana ʻulaʻula i ʻAmelika Hema mai Kekemapa a ʻApelila. ʻO ka wā maikaʻi loa i nā mahina kau wela. Akā hiki ke hoʻololi i ka manawa o ka pūnana i ka pae o ka wai i nā waihona i ka wā ua. Hoʻomaka ka hoʻomaka ʻana o ka Nesting i ka wā pulu. Kūkulu nā pālua no ka manawa lōʻihi, akā ʻaʻole ka poʻe āpau i kahi pilina paʻa.
ʻO ka pūnana kahi kaumaha i loko o ka puʻu mauʻu a aia ma ka honua i waena o nā mea ulu nui, ma kahi kokoke i ka wai.
Mālama ke kāne i kekahi manawa i ka pūnana a pale i ka wahine a me ka paʻa. Hoʻomoe ka wahine i 5 a 12 mau hua. Hoʻokomo i nā paʻa mai 25 a 28 mau lā. Ua holo holoʻokoʻa ʻo Chicks ma hope o ʻelua mau mahina.
Ka mālama ʻana i kahi pālule ʻulaʻula i ka pio
Mālama ʻia nā pālule ʻulaʻula i nā pā manuahi i ke kauwela. ʻO ka liʻiliʻi o ka lumi ma kahi o 3 mau mika kūlike. I ka hoʻoilo, pono kēia ʻano pato i nā kūlana ʻoluʻolu hou aʻe, no laila, hoʻoneʻe ʻia nā ʻāpala ʻulaʻula i kahi hale manu insulated, kahi e iho ai ka mahana ma kahi o + 15 ° C. Hoʻokomo ʻia nā perches mai nā lālā, nā kaʻa a i ʻole nā perches. E hoʻokau i kahi ipu me ka holo a hoʻomaʻamaʻa mau paha i ka wai i ka hale manu. I nā wahi hoʻomaha, waiho lākou i ka mauʻu mai nā mea kanu lau nahele.
ʻAi ʻia nā ʻāʻā ulaʻina i nā ʻano palaoa, nā kulina, nā palaoa, nā palaoa. Hiki iā ʻoe ke hāʻawi i ka oatmeal, bran palaoa, sunflower a me ka ʻai soybean. Hoʻohana ʻia ka iʻa, mauʻu, ʻiʻo a me ka iwi, nā pūpū liʻiliʻi, kapelu, gammarus i ʻaʻahu luna. I ke kauwela a me ke kauwela kau, hiki iā ʻoe ke hānai i nā manu me nā greens like ʻole - ka lettuce, dandelion, plantain. Ulu maikaʻi nā manu i nā meaʻai pulu i hana ʻia mai nā kāloti i kālai ʻia me ka hoʻohui o ka bran a me nā sereala like ʻole.
I ka wā hoʻoulu holoholona a i ka wā hoʻoheheʻe, hāʻawi ʻia nā ʻāʻī i hāʻawi ʻia i ka ʻula a me ka iʻa i hoʻokaʻawale ʻia. Hui pū kēia ʻano pato me nā ʻano ʻē aʻe i ka lumi like a me ka loko iʻa like. I ka pio ʻana, ma kahi o 30 mau makahiki ke ola.
Ke kūlana mālama o ka ʻāpala i hāʻawi ʻia i ka ʻulaʻula
ʻO ka peʻa ʻulaʻula i kanu ʻia he ʻano laha ākea ia ma nā wahi o kona laulā. I ke kūlohelohe, aia kahi hōʻemi iki o ka helu o nā kānaka o kēia ʻano, akā ʻaʻole wikiwiki e hōʻike i nā mea hoʻoweliweli i ka ʻāpala i hāʻawi ʻia i ka ʻulaʻula. Aia kekahi makaʻu weliweli mai ka parasitism o nā leech Theromyzon cooperi a me Placobdella garoui, ka mea e hoʻopili ai i nā manu a alakaʻi i ka make.
I Madagascar, hoʻoweliweli ʻia ka nohona o nā laha e ka loli noho.
Hoʻohui ʻia, manaʻo ʻia ka ʻāʻī pālū ʻulaʻula i mea lawaiʻa a me nā holoholona haʻuki, kahi e hōʻino ai i ka nui o nā manu. Wahi a nā pae hoʻohālikelike e pili ana i nā ʻano laha ʻole, ʻaʻole e hāʻule ka ʻāʻā pālū ʻulaʻula i ka mahele nāwaliwali.
