ʻO ka Galapagos Buzzard kahi manu nui, ʻeleʻele-ʻeleʻele i hopu ʻia mai ka geneo Buteo. He nui kona ʻēheu nui: mai 116 a 140 cm a me ka nui o ke kino o 56 knm. ʻOi aku ka pouli o ka plumage o ke poʻo ma mua o ke koena o nā hulu. Hinahina-ʻeleʻele ka huelo, hina-ʻeleʻele i ke kumu. Flanks a me ka ʻōpū me nā kiko ʻulaʻula. Nā hulu huelo a undertail me nā kaha keʻokeʻo koʻikoʻi. ʻIke pinepine ʻia nā māka keʻokeʻo ma ke kua. Ua hoʻolōʻihi ʻia ka huelo. Ikaika nā paws. ʻO ke kala o ka plumage o ke kāne a me ka wahine like, akā ʻokoʻa nā kino o ke kino, aia ka wahine ma ka awelika 19% ʻoi aku.
He pulu ʻeleʻele eleele nā ʻōpio Galapagos Buzzards. ʻEleʻele nā kuʻemaka a me nā kaha ma nā papalina. Pālahalaha ka hana ʻana i nā pāpālina. Paʻa ka huelo, ʻeleʻele ke kino. Koe wale no ka pahu, keʻokeʻo i ka leo. ʻO nā koena o nā ʻāpana haʻahaʻa ʻeleʻele me nā kiko kukui a me nā kiko. ʻAʻole hiki ke huikau ka helehelena o ka Galapagos Buzzard me kekahi manu manu ʻio. I kekahi manawa lele ʻo osprey a me peregrine falcon i nā mokupuni, akā ʻike nui ʻia kēia ʻano a ʻokoʻa hoʻi mai ka buzzard.
Hoʻolaha o ka Galapagos Buzzard
ʻO ka Galapagos Buzzard kahi hopena o ka pae moku ʻo Galapagos, aia ma waenakonu o ka Moana Pākīpika. A hiki i kēia manawa, aia kēia ʻano ma nā mokupuni āpau, koe wale no nā ʻĀkau o Culpepper, Wenman a me Genovesa. ʻO ka helu o nā manu ma lalo nui ma ka moku waena nui o Santa Cruz. Ua pau loa ka Galapagos Buzzard ma 5 mau moku liʻiliʻi e pili ana (Seymour, Baltra, Daphne, Chatham a me Charles). 85% o nā kānaka e kia ma 5 mau mokupuni: Santiago, Isabella, Santa Fe, Espanola a me Fernandina.
ʻO Galapagos Buzzard wahi noho
Hoʻolālā ʻia ka Galapagos Buzzard i nā wahi noho āpau. ʻIke ʻia ia ma kahakai, ma waena o nā pūnaewele pele ʻole, e kau ana ma luna o nā piko kuahiwi. Wehe ʻia nā wahi noho, nā wahi pōhaku e ulu ana me nā nāhelehele. Noho i nā ululāʻau deciduous.
Nā hiʻohiʻona o ka hana a Galapagos Buzzard
Noho wale ʻo Galapagos Buzzards a i ʻole pālua paha.
Eia nō naʻe, i kekahi manawa ʻākoakoa nā hui nui o nā manu, ʻumeʻume ʻia e ke kino. I kekahi manawa ʻike ʻia nā hui kamahaʻo o nā manu ʻōpio a me nā wahine hānau ʻole. Eia kekahi, i nā manawa pinepine, i nā buzzards o Galapagos, he mau kāne 2 a 3 mau kāne paha me hoʻokahi wahine. Hoʻokumu kēia mau kāne i nā hui e pale i ka ʻāina, nā pūnana a me ka mālama ʻana i nā moa. Pau nā lele moena āpau i ka lewa, a hele pū me nā ʻuwā. Luʻu pinepine ke kāne mai kahi kiʻekiʻe loa me kona mau wāwae i hoʻohaʻahaʻa ʻia a hoʻokokoke i kahi manu ʻē aʻe. ʻAʻohe o kēia ʻano manu lele i kahi nalu e like me ka "lani-hula".
Holo ʻo Galapagos buzzards i nā ʻano like ʻole:
- hopu pio i ka lewa;
- e nānā mai luna mai;
- hopu ʻia ma ka ʻili o ka honua.
I ka lele lele ʻana, loaʻa nā ʻiʻo hulu i ka mea pio a luʻu iā ia.
ʻO Galapagos Buzzard ka hoʻohua
Hāpai ʻo Galapagos Buzzards i loko o ka makahiki, akā kānalua ʻole ka wā kiʻekiʻe aia i Mei a mau a ʻAukake. Kūkulu kēia mau manu manu i kahi pūnana ākea mai nā lālā i hoʻohana hou ʻia no kekahi mau makahiki i ka lālani. ʻO ka nui o ka pūnana he 1 a me 1.50 mau mika i ke anawaena a hiki i 3 mika ke kiʻekiʻe. Hoʻopili ʻia ka loko o ka pola me nā lau ʻōmaʻomaʻo a me nā lālā, ka mauʻu a me nā ʻāpana o ka ʻili. Aia ka pūnana ma kahi kumulāʻau haʻahaʻa e ulu ana ma ka lihi pele, ka ʻalā pōhaku, ka pōhaku i waho, a i ʻole ma ka honua i waena o nā mauʻu kiʻekiʻe. Aia he 2 a ʻekolu paha mau hua i loko o kahi paʻa, i hoʻouluulu ʻia nā manu no 37 a i ʻole 38 mau lā. Hoʻomaka ka lele ʻana o Young Galapagos Buzzards ma hope o 50 a 60 paha mau lā.
ʻOi aku ka lōʻihi o kēia mau manawa ʻelua ma mua o ka hoʻomohala ʻana o ka moa e like me nā ʻano o ka ʻāina nui.
Ma ke ʻano he kūlana, hoʻokahi wale nō moa e ola i ka pūnana. Hoʻonui ʻia ka likelihood o ke ola ola ʻana e ka mālama pūʻulu ʻana i nā buzzards makua, nā mea e kōkua ai i nā manu ʻelua e hānai i nā buzzards ʻōpio. Ma hope o ka haʻalele, noho lākou me ko lākou mau mākua no kekahi mau mahina 3 a 4 paha. Ma hope o kēia manawa, hiki i nā buzzards ʻōpio ke alualu iā lākou iho.
E hānai ana i ka Galapagos Buzzard
No kekahi manawa lōʻihi, ua manaʻo ka poʻe loea he maikaʻi ʻole nā buzzards Galapagos i nā fringillidae a me nā manu. Manaʻo ʻia ʻo kēia mau manu lele e alualu wale lākou i nā moʻo liʻiliʻi a me nā invertebrates nui. Eia nō naʻe, he mau māiʻuʻu ʻoi loa nā buzzards o Galapagos, no laila ʻaʻole ia he mea kupanaha ke hōʻike ʻia nā noiʻi hou e pili ana nā manu kai a kahakai e like me nā nūnū, nā mockingbirds a me nā fringilles. Hopu pū ʻo Galapagos Buzzards i nā moa a peck i nā hua o nā manu manu ʻē aʻe. Alualu lākou i nā iole, nā moʻo, nā iguana ʻōpio, nā kuhukukū. Hoʻouka lākou i nā keiki i kēlā me kēia manawa. E hoʻopau i nā kupapaʻu o nā sila a i ʻole nā capridés. I kekahi manawa hōʻiliʻili ʻia ka iʻa kūpaʻa a me nā ʻōpala o ka hale.
Ke kūlana mālama o ka Galapagos Buzzard
Ma hope o ka helu kanaka hou ʻana, helu ka 35 ʻo Galapagos Buzzard ma Isabella Island, 17 ma Santa Fe, 10 ma Espanola, 10 ma ka mokupuni ʻo Fernandina, 6 ma Pinta, 5 ma Marchena a me Pinzon, a he 2 wale nō ma Santa Cruz. Noho kekahi poʻe 250 ma ka pae ʻāina. Inā mākou e noʻonoʻo i nā kāne ʻōpio ʻaʻole i hānau, huli ʻia ma kahi o 400 - 500 mau kānaka.
I nā makahiki i hala iho nei, ua emi iki ka heluna kanaka e pili ana i ka ʻimi manu ʻana o nā manu e nā naturalist amateur, a me nā pōpoki e hānai a holo wale ana ma nā mokupuni. I kēia manawa ua kū ka hāʻule o ka helu o nā buzzards laha ʻole, a ua kūpaʻa ka helu o nā kānaka, akā hoʻomau ka ʻimi manu ʻana iā Santa Cruz a me Isabela. Ma ka ʻāina nui o ka mokupuni ʻo Isabela, he liʻiliʻi ka helu o nā manu laha nui o ka manu ma muli o ka hoʻokūkū no ka meaʻai me nā pōpoki hānai a me nā mea ʻino ʻē aʻe.
Hoʻokaʻawale ʻia ʻo Galapagos Buzzard ma ke ʻano he Vulnerable ma muli o kona palena o ka mahele o ka mahele (ma lalo o 8 kilomika kilomika).
