ʻO ka Laysan teal (Anas laysanensis) no ka ʻohana duck, kauoha anseriformes.
Nā hōʻailona kūwaho o ka Laysan teal.
He kino ka nui o Laysan teal of 40 - 41 cm. ʻO ke kaumaha o kēia peʻa liʻiliʻi 447 gram. Liʻiliʻi ke ʻano o ke kāne a me ka wahine. He nuku brownish-ʻōmaʻomaʻo ʻōmaʻomaʻo ke kāne, kahi kiko ʻeleʻele i ke kumu. ʻEleʻele-melemele ka nuku o ka wahine, ʻalani ʻalani hapa ma nā ʻaoʻao.
ʻO ka plumage o ke kīʻaha Laysan he brownish-ʻulaʻula i ke kala me nā kaha ʻōuli ʻeleʻele i ʻike maopopo ʻia. ʻEʻeleʻele ke poʻo a me ka ʻāʻī me nā kiko keʻokeʻo alternating. Ma kahi kokoke i ka nuku a puni nā maka, ʻike ʻia nā mālamalama like ʻole, a hoʻonui ʻia i kekahi manawa i ka auwae. Ma nā ʻaoʻao o ke poʻo nā wahi keʻokeʻo kaulike o ke keʻokeʻo. Loaʻa i ka kāne nā hulu ʻelua me nā ʻōmaʻomaʻo a uliuli hoʻi, ʻeleʻele i nā wēlau. ʻO nā hulu uhi nui me kahi palena keʻokeʻo. ʻIke ʻia nā wahine makua a me nā ʻōpio e nā hulu kula ʻelua o ʻeleʻele ʻeleʻele a i ʻole ʻeleʻele hina hina a me nā underwings keʻokeʻo.
ʻOi aku ka kala o ka wahine ma lalo o ke kāne ma mua o ke kāne, ʻoiai ka laulā o nā hulu ʻeleʻele i ka hulu. Loaʻa i nā kāne ʻōpio nā hulu o ka huelo i ʻōwili ʻia. ʻAlani nā wāwae a me nā wāwae. ʻEleʻele ka iris o ka maka.
E hoʻolohe i ka leo o ka Laysan teal.
ʻO nā wahi noho keaka ʻo Laysan.
He ʻokoʻa loa nā kuke Laysan mai nā manu ʻāinapuniʻole e ko lākou kūlana, akā ʻano like lākou ma nā ʻano he nui i nā manu ʻē aʻe e noho ana ma nā mokupuni. Loaʻa lākou ʻelua ma ka wai a ma ka ʻāina, e hoʻohana ana i nā wahi āpau i loaʻa ma ka mokupuni ʻo Laysan. Noho kēia ʻano i nā puʻu one me nā mea ulu liʻiliʻi, nāhelehele a me nā wahi o uka, a me nā ulu ulu e hoʻopuni ana i nā loko. Hele kipa aku ʻo Laysan i nā wahi lepo a me nā wahi lepo. Hānai lākou i ke ao a me ka pō, e noho mau ana no kahi manawa lōʻihi i nā wahi kahi meaʻai. ʻO ke kū ʻana o nā kumuwaiwai wai hou kahi kūlana koʻikoʻi no ka loaʻa ʻana o nā tī Laysan.
ʻO ka pālahalaha ʻana o ke koʻi Laysan.
Noho ʻo Laysan teals i kahi wahi liʻiliʻi loa, aia ma 225 km ka mamao ma ka mokupuni kokoke loa ma ka ʻaoʻao komohana komohana o ka pae ʻāina ʻo Hawaiʻi. ʻO kēia ʻāpana ʻāina he mokupuni lua pele ia, aia ka nui ma 3 km a 1.5 km, a ʻaʻole i ʻoi aku kona ʻāpana i 370 maueka.
ʻO nā wahi noho keaka ʻo Laysan.
ʻIke ʻia nā ʻōiwi Laysan ma nā lagoons me ka wai brackish, kahi e noho mau ai lākou.
Nā hiʻohiʻona o ka lawena o ka Laysan teal.
Noho pālua ʻo Laysan i nā hui pālua a i ʻole nā hui liʻiliʻi. Hānai lākou e hoʻoheheʻe ma hope o ka hānau ʻana. Hoʻohana nā manu i kekahi manawa i nā puddles liʻiliʻi o kai kai i koe mai ke kai haʻahaʻa e ʻauʻau, no ka mea ʻoi aku ka maikaʻi o ka wai ma laila ma mua o ka loko. A laila noho lākou i lalo e hoʻomaha i ka pāpaʻu e mahana a pālahalaha i ko lākou hulu ma hope o ka ʻauʻau ʻana, i kēlā mau manawa ʻaʻole loaʻa ka meaʻai. ʻAʻole ʻauʻau mamao loa nā ʻōiwi Laysan mai ke kapakai, pale i nā nalu nui a makemake i nā kahawai mālie. I ke ao, peʻe ka manu i ka malu o nā kumu lāʻau a i ʻole nā laʻalāʻau nui e ulu ana ma nā puʻu.
ʻO Laysan teal.
Ua aʻo ʻia nā kikoʻī āpau o ka loina o ka lawena ʻōiwi Laysan i ke ʻano o nā manu pio, a ʻano like me ke ʻano o ka moena o ka ʻupena mallard. He monogamous kēia mau manu a he pilina matrimonial ʻoi aku ka paʻa ma mua o nā ʻikeke i loaʻa ma ka ʻāina.
E like me ka nui o nā ʻāpō, kūkulu nā ʻōlapa ʻo Laysan i kahi pūnana mai nā mea kanu. Liʻiliʻi, ʻōpuni a hūnā pinepine ʻia i waena o nā mea kanu.
Kau ʻia ka uhi e ka wahine mai lalo. He lōʻihi ka wā pūnana, akā he loli ka manawa, no ka hoʻololi paha i ka pae o ka wai. Hoʻohana maʻamau nā ʻōiwi Laysan i ka puna a me ke kauwela, mai Malaki a Iune, a mai ʻApelila a Iulai. ʻOi aku ka akahai o ka nui o ka paʻa, aia ma kahi o 3 a 6 mau hua i ka pūnana. Hoʻokomo ka wahine i ka lālau ma kahi o 26 mau lā.
Alakaʻi ʻia a hānai ʻia ka pua e ka wahine, ʻoiai kokoke ke kāne i kekahi manawa. He mea nui ka hatch o nā moa i loko o nā pule ʻelua, no ka mea hiki i ka ua nui ke make i ka pua. Pale aku ʻo Chicks i kahi pēpē makua a hiki i ko lākou kūʻokoʻa ʻana. Malia paha, ka hoʻohui ʻana o kekahi mau broods o nā makahiki like ʻole, i hana pinepine ʻia.
ʻO kaʻai kā Laysan teal.
Makemake nā ʻōlapa ʻo Laysan e hānai i nā invertebrates no ka hapa nui o ka makahiki.
I ke kauwela, wehe nā manu makua i kā lākou mea pio mai ka silt a me ka lepo me ko lākou nuku me nā neʻe ʻoi.
Nānā pū lākou i nā kupapaʻu manu make e huki i nā larva o nā nalo a i ʻole nā mea kolo ʻē aʻe. ʻO Shrimp, ka mea nui i ka loko, kahi waiwai pū kekahi o nā meaʻai. Ke holoholo nei nā ʻōiwi Laysan o nā makahiki āpau i ka pō ma nā wahi kiʻekiʻe o ka mokupuni e ʻimi ana i nā ʻenuhe o nā ʻano moth, i nui i ka lepo one. ʻAʻohe mea kanu wai no ka meaʻai i loko o ka loko, paʻakikī loa ka limu e ʻai ʻia. ʻAʻole maopopo i kēia manawa nā ʻanoʻano a me nā hua a nā Laysan teals e ʻai ai. Hoʻohana ʻia paha nā ʻanoʻano sedge. ʻO kahi mea ʻai nui ʻo Scatella sexnotata, ka nui o ia mau mea e hoʻonui ai i ka hānau hou ʻana o ka Līthan teal.
Ke kūlana mālama o ke kō Laysan.
Hoʻokaʻawale ʻia ke kīʻaha Laysan me he mea lā hoʻoweliweli. Ua ʻōlelo ʻia kēia ʻano i ka CITES Appendix. Noho ʻo ia i ka National Wildlife Refuge ma Hawaii.
Ka pale ʻana i ke koʻi Laysan.
No ka mālama ʻana i ke kī ʻo Laysan, ke hoʻokō ʻia nei kahi papa hana hoʻihoʻi manu piha e ka US Fish and Game Services. I ka makahiki 2004-2005, ua neʻe ʻia he 42 mau manu hihiu mai Laysan Island a i Midway Atoll. ʻO ka papahana, e hana nei ma Midway Atoll, e pili ana i ka nānā ʻana, ka noiʻi kaiaola a me ka lāhui kanaka o ka laha, a me ka hoʻomaikaʻi ʻana o ka wā kahiko a me ka hana ʻana i nā ʻāina wai hou. ʻO ke kumumanaʻo e alualu ʻia nei e hoʻopili ana i ka hoʻokomo ʻana i ka wai i kēlā me kēia makahiki, ka hoʻokahe ʻana a me ka hoʻomaʻemaʻe ʻana i ka wahi paʻa e hoʻoneʻe i nā ʻōpala i hōʻiliʻili ʻia, e hoʻohana ana i nā mīkini kaumaha a me nā pauma lawe e hoʻomaikaʻi i ka maikaʻi o ka wai.
Hoʻopili nā hana mālama i ka hoʻonui ʻana i nā pūnaewele pūnana a me ke kanu ʻana i nā mauʻu sodoma kūloko.
Ke lawe nei i nāʻiole mai kahi moku one e luku i nā mea kanu. Hoʻonohonoho hou ka Ecosystem i kahi hou o ʻekolu mau lāhui hou aʻe o nā ʻāpō kaka ʻole. E hōʻoia i ka mākaʻikaʻi mākaʻikaʻi e pale i ka hoʻolauna wale ʻana o nā mea kanu exotic, invertebrates a me nā holoholona i hiki ke hoʻopilikia maoli i ke kī ʻo Laysan. Lawe i ka lawe hou ʻana aku i nā moʻo e hoʻonoho hou i nā manu i ko Hawaiʻi pae ʻāina ʻē aʻe. Loiloi i ka loli ʻana o ka nohona o nā lehulehu a hoʻohui i nā mea hou. Ke loiloi ʻia nei ka lāʻau ʻana i nā ʻāpala ma Midway Atoll e pale aku ai i ka hoʻolaha ʻana o ka botulism avian.
