ʻO ka merganser i hoʻonui ʻia (Mergus squamatus) pili i ka ʻohana duck, ke kauoha Anseriformes.
Nā hōʻailona kūwaho o kahi scaly merganser.
ʻO ka merganser i hoʻonui ʻia ka nui o ke kino ma kahi o 62 cm, kahi ʻēheu o 70 a 86 cm. Kaona: 870 - 1400 g. E like me nā ʻohana pili pili ʻohana o ka ʻohana duck, hōʻike kēia ʻano i ka dimorphism moekolohe a me nā loli kū i ke kala o ka plumage i haʻi ʻia.
ʻO ke kāne i ka wā lūlū he lōʻihi lōʻihi lōʻihi a kau ʻia. ʻEleʻele ke poʻo a me ka ʻāʻī me kahi ʻōmaʻomaʻo ʻōmaʻomaʻo, kahi mea hoʻohālikelike nani me nā ʻōmaʻomaʻo keʻokeʻo momona me kahi aniani ʻulaʻula ma lalo o ka ʻāʻī a me ka umauma. ʻO Flanks, ʻōpū lalo, sus-tail, Sacum a me hope kahi hoʻonohonoho nui o nā pale keʻokeʻo me nā hina hina hina nui loa ma nā ʻāpana. No kēia hiʻohiʻona o ke kala o ka plumage, ua wehewehe ʻia kēia ʻano he scaly. ʻEleʻele nā hulu uhi o ka ʻāʻī a me ka ʻāpana scapular. ʻOkoʻa ka wahine i ke kala o ka plumage mai ke kāne. He ʻāʻī ʻulaʻula ʻulaʻula kona a me ke poʻo me nā kahakaha keʻokeʻo i hoʻopuehu ʻia ma lalo o ka ʻāʻī, ʻāpana o ka umauma a ma waena o ka ʻōpū. ʻO nā ʻāpana o ka ʻāʻī, nā ʻaoʻao, nā ʻaoʻao lalo o ka ʻōpū a me ka sacum i loaʻa i ke ʻano scaly keʻokeʻo keʻokeʻo. I ke kauwela, nalowale ke ʻano scaly, lilo nā ʻaoʻao a me ke kua i hina, e like me nā pēpē ʻōpio.
ʻO nā mergansers ʻōpio ʻōpiopio e like me nā wahine. Loaʻa iā lākou ke kala o nā manu makua i ka hopena o ka hoʻoilo mua. ʻUlaʻula ka nuku me ka wēlau pouli. ʻUlaʻula nā wāwae a me nā wāwae.
ʻO ka wahi noho o ka scaly merganser.
Loaʻa i nā mergansers scaly ma nā kahawai ʻo nā kapa kiʻekiʻe i kūkulu ʻia e nā lāʻau kiʻekiʻe.
Makemake lākou e noho i nā wahi o nā ululāʻau huikau me nā ʻano deciduous a me coniferous ma nā pali i kahi kiʻekiʻe ma lalo o 900 mau mika.
ʻO nā ululāʻau kumu mua me nā kumulāʻau nunui e like me nā ʻelima, nā lindens a me nā popela, akā ʻo nā ʻoka a me nā pine kekahi e koho maʻamau ʻia. ʻO nā wahi me nā kumulāʻau kahiko mahalo nui ʻia e nā manu no nā ʻano pūnana maikaʻi, ʻoiai he nui ko lākou mau lua.
I ka hōʻea ʻana i nā wahi pūnana, ʻike mua ʻia ka scg merganser ma nā kapa o nā muliwai a me nā loko, ma mua o ka noho ʻana ma kapa o nā muliwai liʻiliʻi no ka pūnana. I Rūsia, koho nā pālolo i nā ʻāina mauna a puʻu paha ma nā kahawai me nā kahe mālie a me nā wai aniani maikaʻi, nā mokupuni, nā ʻiliʻili a me nā ʻeke one. I Kina, ʻaʻole ʻokoʻa loa ke koho: nā kahawai me nā piʻo he nui a me nā meaʻai momona, me ka kahe mālie a me ka wai maʻemaʻe, pōhaku a me ka ʻalu o lalo. I kekahi mau wahi mauna, noho mau ka poʻe wīwī scaly kokoke i nā pūnāwai, ʻoiai ʻaʻohe muliwai nui ma kēia mau wahi.
Ma waho o ka wā hānau, mai ʻOkakopa a Malaki, ʻai nā ʻāpō i nā kapa o nā muliwai nui, ma nā ākea ākea.
Nā hiʻohiʻona o ka lawena o ka scaly merganser.
Noho pālua nā mergansers scaly a i ʻole nā hui ʻohana liʻiliʻi. ʻAʻole paʻa kēia mau hipa no ka mea pili paʻa nā pūʻulu liʻiliʻi o nā ʻāpō ʻōpio. Hoʻohui ʻia, i ka mua o Iune, ke hoʻouluulu nei nā wahine, ʻākoakoa nā kāne i 10 a 25 mau kānaka a hana i nā neʻe pōkole e hoʻoheheʻe ʻia i nā wahi mehameha.
Haʻalele nā wahine a me nā ʻāpō ʻōpio i nā pūnaewele pūnana mai ka waena o Kepakemapa a i ka mua o ʻOkakopa. ʻO ka neʻe ʻana i ka waena a me lalo o ka muliwai mai nā wahi pūnana ka pae mua i kahi huakaʻi lōʻihi i nā wahi hoʻoilo. Ma hope iki, hele nā manu i nā kapa o nā muliwai nui o Kina waena. E hoʻi i nā pūnaewele hoʻonohonoho i ka hopena o Malaki a i ʻole ʻApelila mua
Palapala hoʻomaikaʻi scaly merganser.
I ka wā hānau, loaʻa nā mea wīwī scaly i ka meaʻai kokoke i ka pūnana, ma loko o hoʻokahi a ʻelua mau mile paha. Hoʻololi mau ka wahi hānai i loko o ka wahi i hoʻopaʻa ʻia, ʻo 3 a 4 paha mau mile ka lōʻihi. I kēia manawa o ka makahiki, 14 a 15 paha mau hola e loaʻa ai ka meaʻai. Mālama ʻia kēia wā hānai i nā hui liʻiliʻi o ʻekolu manu, akā hoʻolōʻihi ʻia i ka wā o ka neʻe ʻana.
Hoʻopili ʻia nā lele lōʻihi me nā wā hoʻomaha pōkole ke palaki nā ʻāpala i ko lākou hulu a ʻauʻau.
I Kina, ʻo ka meaʻai o ka scaly merganser kahi o nā holoholona wale nō. I ka wā o ka pūnana, noho nā larvae ʻohana e noho ana ma lalo o ka ʻiliʻili ma kahi o 95% o ka mea pio i ʻai ʻia. Ma hope o Iulai, hoʻololi nui ka papaʻai o nā ʻāpō, hopu lākou i nā iʻa liʻiliʻi (char, lamprey), kahi e peʻe ai i nā māwae ma waena o nā pōhaku ma lalo o ka muliwai, a me nā crustacea (shrimp and crayfish). Mālama ʻia kēia meaʻai i ka mahina ʻo Kepakemapa, ke ulu a puaʻa ʻōpio.
I ka wā hānau, he kakaikahi nā mea hoʻokūkū meaʻai i nā scaly mergansers. Eia nō naʻe, e hoʻomaka ana i ʻOkakopa, ke lele lākou i ke kapa o nā muliwai nui, ma waho o ka ululāʻau, hānai lākou e hui pū me nā ʻano pākī luʻu ʻē aʻe, he ʻenemi kūpono nā lunamakaʻāinana o ka Anatidae i ka ʻimi ʻana i ka meaʻai.
Hoʻohua a me ka pūnana o ka scaly merganser.
ʻO nā manuā Scaly mergansers he mau manu monogamous maʻamau. Hiki i nā wahine ke oʻo i ka moekolohe a hoʻomaka i ka hānau hou i ka makahiki ʻekolu.
Hōʻike ʻia nā manu ma nā pūnaewele pūnana i ka hopena o Malaki. Hana ʻia ka hui paʻa ma hope koke iho, i ka mahina o ʻApelila.
ʻO ka wā hānau hānau mai ʻApelila a Mei a hoʻomau i Iune i kekahi mau wahi. Noho kekahi pālua pūnana i kahi ma kahi o 4 mau mile ma ke kapa o ka muliwai. Hoʻonohonoho ʻia kahi pūnana manu ma kahi kiʻekiʻena o 1.5 mika a hiki i 18 mika mai ka honua. Loaʻa ka mauʻu a me ka fluff. Hoʻokomo ʻia ka pūnana ma luna o kahi kumulāʻau kahakai e nānā pono ana i ka wai, akā ʻaʻole pinepine ia ma 100 mau mika mai ke kahakai.
I loko o kahi paʻa, aia mai ka 4 a i ka 12 mau hua, ma nā hanana kūʻokoʻa i hiki i ka 14. Ma ke ʻano he rula, he hoʻokahi lālau paʻa nā scaly mergansers i kēlā me kēia makahiki. Eia naʻe, inā make nā moa mua no kekahi kumu, hana ka ʻūlū i ka lua o ka paʻa. Hoʻokomo wale ka wahine i kahi manawa i hiki ke ʻokoʻa mai 31 a 35 mau lā. Hōʻike nā moa mua i ka waena o Mei, akā ʻo ka hapa nui o nā ʻāpō hatch i ka hopena o Mei a me Iune mua. Hiki mai kekahi mau puaʻa ma hope o ka waena o Iune.
Haʻalele nā Chicks i ka pūnana i nā lā he 48-60. Ma hope koke iho, hōʻiliʻili lākou i nā pūʻulu ma kahi o 20 mau kānaka, alakaʻi ʻia e kahi ʻāpua makua. Ke hiki i nā ʻāpō ʻōpio i ka makahiki o 8 mau pule, ma ka maʻamau i nā makahiki he 10 i hala o ʻAukake, haʻalele lākou i ko lākou mau pūnaewele pūnana.
