Pakati pa mbalame za kunyanja, njira yodzaza ndi moyo ndiyofala kwambiri. Imodzi mwa mbalamezi ndi cormorant. Mbalame yokhala pagulu imakhala yolimba mtima kwambiri ikakhala m'midzi, pamakhala mwayi wopitilira kubereka, komanso mwayi wochepa wogwidwa ndi nyama yomwe imadyedwa nayo.

Zachidziwikire kuti aliyense nthawi ina adamvapo wina mwachipongwe chotchedwa cormorant. Kodi themberero limakhudzana ndi mbalameyo kapena ayi, ndipo ngati itero, ndiye chifukwa chake sizikudziwika bwinobwino. Onse "wamba" amaika patsogolo mitundu yosiyana! Mwanjira ina iliyonse, mitundu yonse ya anthu siyimasiyanaku ndi mbalame zachilendozi.
Padziko lonse lapansi, mitundu ya mbalame za m'madzi - ma cormorants. Iwo ndi a banja looneka momasuka kuchokera kumayendedwe ofanana ndi mafupa am'mimba.

Zachilendo - mawonekedwe wamba

Mwachilengedwe, pali mitundu yopitilira 30 ya mbalamezi, koma pali ena mwa mawonekedwe awo, chifukwa omwe ali pang'ono ngati anzawo. Ma cormorants onse ndi akulu kwambiri, ambiri amakula ngati tsekwe la Khrisimasi kapena bakha wopanda mafuta.

Cormorant (lat.Phalacrocorax)

Kutalika kwa thupi nthawi zambiri kumafikira mita, ndipo mapiko amatha kupitirira mita imodzi ndi theka. Mlomo wowonda, khosi lalitali loonda, miyendo yoluka, nthenga zakuda zokhala ndi chitsulo chachitsulo, komanso kusintha kwa nthenga kawiri pachaka, ndizo mwina zonse zomwe m'bale-cormorants amafanana. Ndipo akazi awo ndiosiyana amuna okhaokha, monga oimira amuna onse ogonana ali ocheperako komanso "ocheperako" kuposa mitu ya chisa.

Cormorants

Nsomba ndi chakudya chomwe amakonda kwambiri, ndipo amatha kupita kukasaka m'magulu akuluakulu, atatenga anzawo a pelican. Khamu la anthulo, amayendetsa nsomba kuti zizipeza madzi osaya, pomwe wina aliyense amawatsitsa.

Cormorant ndi asodzi opatsa mwayi kwambiri.

Cormorant amatha kudya mpaka pafupifupi nsomba tsiku lililonse. Ma cormorants am'madzi oyera amapangitsa kuti zakudya zawo zizikhala zosiyanasiyana ndi nsomba zazinkhanira ndi achule.

Cormorant ndi bambo

Kwa nthawi yayitali, nthumwi za China ndi Japan zidagwiritsa ntchito ma cormorant pophera nsomba. Tsopano miyambo imeneyi imasungidwa m'malo ena ngati kukopa: akatswiri ophunzitsidwa bwino amalowera nsomba usiku, ndipo nyali zimayatsidwa m'mbali mwa gombe.

Kugwira nsomba ndi cormorant.

Izi sizongowoneka zokongola zokha, komanso phindu lodabwitsa, chifukwa munjira imeneyi mutha kusonkhanitsa dengu lonse la nsomba mu nthawi yochepa kwambiri.
Ziphuphu ndizofunikira osati luso lawo, komanso mu chilengedwe chawo. Dontho la mbalame za Guano, lomwe ndi imodzi mwazinthu zofunikira kwambiri feteleza, ndizomwe mbalame imatha kudzitamandira.

Bwenzi kapena mdani?

Khwangwala amathanso kuwaona ngati mdani wa cormorant, yemwe amayesetsa kukoka mazira pachisa, nthawi zina mbalame zam'mimba ndi mbalame za m'madzi zimasaka mazira. Ndipo anapiye ang'onoang'ono atha kukhala ankhandwe a nkhandwe zakutchire, coyotes ndi akambuku.

Ngati mwapeza cholakwika, chonde sankhani gawo ndikusindikiza Ctrl + Lowani.

Chiyambidwe cha mafotokozedwe ndi kufotokozera

Cormorant wochokera ku gulu lachiwonetsero chokhala ngati ziwalo za ziwalo. Mbalame yamadzi iyi ndi imodzi mwasaka bwino kwambiri pamadzi. Pali mitundu yopitilira 30 ya ma cormorants, amafalikira padziko lonse lapansi! Ngakhale m'dziko lathu, mutha kupeza mitundu isanu ndi umodzi ya mbalamezi.

Mayina amtunduwu nthawi zambiri amatengera mawonekedwe akunja, kapena malo omwe amakhala, izi ndi zina mwazo zomwe zingakumbukiridwe makamaka:

• Great Cormorant ndiye mitundu yoyendayenda kwambiri, imakonda ndege, imatha kupezeka ku Russia, Europe, Africa ndi maiko ena ambiri,
• Chijapani - dzina lake malinga ndi malo okhala,
• Crested - wotchedwa dzina chifukwa chodziwika bwino pamutu pake, walembedwa mu Buku Lofiyira,
• Ang'ono - otchulidwa chifukwa cha kukula kwake,

Chochititsa chidwi: palinso mitundu ina ya ma cormorants yomwe sinathere, iyi ndi mtundu wa Steller cormorant, inali mitundu yosawuluka ndipo inafikira ma kilogalamu 6 kulemera.

Habitat

Ziphuphu zazitali zomwe zimakhala ndi nambala yayitali zimakhala ku Western Palaearctic kuchokera ku Norway kupita ku Iceland, Islands Islands, England, Ireland komanso gombe la Atlantic ku Europe kupita ku Iberian Peninsula, m'mphepete mwa nyanja ya Mediterranean ndi Black Sea komanso kugombe lakumpoto chakumadzulo kwa Africa. Ku Russia, mtunduwu umawonedwa ngati wosowa: wopezeka ku Kola Peninsula pagombe la Murmansk komanso ku Crimea.

Nyanja yayitali ya Atlantic imakhala yofala kwambiri pagombe la Kola Peninsula komanso kuzilumba zina za m'mphepete mwa Murmansk. Chiwerengerocho chinapambana pa cormorant wamkulu, koma, chifukwa chosungidwa ndi malo osungirako "zisumbu zisanu ndi ziwiri" mu 1947, kuchuluka kwa ma cormorants kunatsika kwambiri. The cormorant ya Mediterranean ku Dnieper estuary ndiyochepa, koma m'mphepete mwa chilumba cha Crimea ndizofala ndipo nthawi zina zimakhala zochulukirapo kuposa cormorant wamkulu.

Maonekedwe ndi mawonekedwe ake

Chithunzi: Mbalame ya Cormorant

Wacormorant wamba amalemera pafupifupi ma kilogalamu 2-3, wamwamuna nthawi zonse amakhala wamkulu kuposa wamkazi. Achichepere ali ndi mtundu wa bulauni ndi maula owoneka bwino, pomwe achikulire ndi akuda ndipo amawayika mkuwa kumaso kwawo; Ma subspecies ena ali ndi mawanga oyera pathupi. Palinso mitundu ya Cormorant, mumitundu yambiri momwe mumapangira utoto.

Cormorant chimawoneka ngati tsekwe. Thupi la cormorant lalikulu limatha kukula mpaka masentimita 100, koma mapiko ake adzakhala a 150, omwe akuwoneka bwino kwambiri. Mlomo wa cormorant ndiwamphamvu, nthawi zambiri wachikasu komanso wowongoka kumapeto, ngati loko kapena mbewa, amakhalanso ndi miyendo yayikulu ndi nembanemba komanso khosi losunthika, chilengedwe chonsechi chinapatsa Cormorant kuti ikhale yosavuta nsomba.

Kanema: Cormorant

Zimasunthira mumizere yamadzi mpaka 2 metre pa sekondi. Minofu imakhala ndi hemoglobin yayikulu, motero imatha kukhala pansi pa madzi kwa mphindi zitatu. Amakhulupirira kuti kuchuluka kwa ma cormorants kumatha kuchotsa mpweya wambiri, womwe umawathandiza kulowa pansi kwambiri, mpaka ma 15 metres. Chungacho chimaphimba nthenga zake zachilendo kwambiri, chitatsika pansi, chimasunthira kumtunda ndikutambasula mapiko ake kuti posakhalitsa ziume.

Cormorant amatsogolera mosaka, amasaka nyama m'madzi, ali m'madzi opanda kanthu, kapena mutu umodzi amangotuluka, atatsata chandamale, amadzuka mwakachetechete ndikumenya munthu wosauka uja ngati muvi, kenako nkuthyola matupi ake ndi mulomo wake ndi kuwumeza. Liwu la ma cormorants ndilotsika komanso lakuya, zikuwoneka ngati akufuula ndi mtima wonse kapena akungomenyetsa.

Chosangalatsa: cormorant imawoneka ngati ikuwuluka pansi pamadzi, imatha kugwira ntchito osati ndi miyendo, komanso ndi mapiko ake.

Amuna ndi akazi: kusiyana kwakukulu

Ziphuphu sizikhala ndi gawo logonana. Kusiyana pakati pa amuna ndi akazi ndikuti zakale ndizokulirapo. Mbalame zazing'ono nthawi zambiri zimasiyana mumtundu wamitundu yambiri kuchokera ku mbalame zazikulu. Achinyamata ndi a bulauni, osiyana ndi ma cormorants akuda. Kuphatikiza apo, mitundu yamitundu yambiri ya ma cormorants imasintha pa nthawi yakukula. Kuwala kotalika kwamtunduwu kumawonekera pamutu wa mbalameyo, ndipo malo onse osakhala ndi khungu amatenga mitundu yowala - yobiriwira, yofiyira, yachikaso kapena yamtambo.

Kodi cormorant amakhala kuti?

Chithunzi: Chinyama chambiri

Cormorant ndi mbalame yosamukira ndipo nsomba zikangolowa mu dziwe lomwe amazikonda, limawuluka kumalo otentha, nthawi zambiri imakhala ku Mediterranean kapena kumpoto kwa Africa. Koma ma cormorants aku South Asia anali ndi mwayi, ali ndi nsomba zambiri, ndipo sizinathe, motero sangasamuke.

Ngati ma cormorants adadikirira kuzizirira kwa madzi osungirako komwe amakhala, nthawi yozizira imakhala m'malo otentha, koma ndikubwerera ndi mayendedwe oyamba a chipale chofewa, awa, oyimira mbalame sapezeka m'malo ozizira kwambiri padziko lapansi. Ma cormorants amakhala padziko lonse lapansi ndipo monga chitsimikizo cha izi, nayi mndandanda wa malo omwe mungawawone pafupipafupi:

• Russia
• Australia
• Asia
• Armenia
• Azores,
• Zilumba za Canary
• Mediterranean
• Girisi
• Algeria
• Kumpoto kwa Africa
• Azerbaijan
• Nyanja ya Aral
• Amereka
• Zilumba za Pacific.

Mdziko lirilonse, ma cormorants ali ndi malingaliro apadera, mwa ena amawonongeka, chifukwa chowonongeka, chifukwa ma cormorant samakhala ochezeka, amatha kuwukira bwato ndi kuwugwira ndikuwugwetsa m'madzi, m'masodzi achinsinsi adya gawo la mkango la nsomba.

Chochititsa chidwi: M'mayiko ena, mwachitsanzo, ku Asia, ma Cormorants amagwiritsidwa ntchito ngati ndodo yokhonya ndi nsomba, modabwitsa, mphete imayikidwa khosi la mbalame, thukuta limalumikizidwa ndikumasulidwa kuti afufuze, Cormorant kunja kwazikhalidwe amayamba kuwedza, koma sangathe kumeza chifukwa cha mphete iyi pakhosi! Zotsatira zake, nyamayo imachotsedwa ndi msodziyo ndipo mbalameyo imamasulidwanso kuti ikasaka. Ku Japan, mbalame zachikulire zimatengedwera kukasaka, koma ku China, m'malo mwake, amakonda mbalame zazing'ono ndikuziphunzitsa.

Kufotokozera kwa mbalame

Mbalamezi zimatha kukhala zazitali komanso zazikulu, mpaka kutalika kwa mita ndi mapiko mpaka mita imodzi ndi theka. Ali ndi nthenga zakuda zonyezimira, anthu ena ali ndi nthenga zoyera pamitu yawo komanso mosakhulupirika, ena amakhala ndi mitu. Maonekedwe, amafanana ndi abakha m'njira zina, amathira pansi ndi kusambira mokongola, chifukwa ma thunzi awo ndi amphamvu komanso ali ndi nembanemba.

Thupi la mbalameyi limakhala ndi khosi lalitali komanso mlomo. Pophera nsomba, mulomo ndi wotseguka, mbalameyo imameza nsomba yayikulu. Mlomo wa mbalame ndi wocheperako komanso wautali, kumapeto kwake umakhala wakuthwa ngati mbeza. Mawu a mbalamezo ali ngati kakhola kapena ogontha ogontha, okhala ndi zolemba mokweza mawu. Pamutu komanso mozungulira maso, mbalame zamtunduwu zawulula malo amkanda osaphimbidwa ndi maula, komanso gawo la mmero.

Mu chilengedwe, pali mitundu khumi ndi iwiri yamadzi am'madzi amtunduwu, ndipo cormorant wamkulu amawonedwa ngati woimira banja lalikulu.

Kodi cormorant amadya chiyani?

Chithunzi: Cormorant ndi nsomba

Cormorant amadya nsomba zokha ndikudyetsa anapiye ake, sizimakonda mitundu iliyonse, m'malo mwake, zimatengera komwe mbalameyo ili. Kutengeka ndi kusaka, iye akhoza kumeza nsomba za nkhanu, ndi achule, akamba komanso ngakhale nsomba zazinkhanira, zonse, zomwe zimalowa mkamwa mwake pakasaka.

Cormorant imameza tinsomba kamodzi nthawi yomweyo, kwinaku ikukweza mutu, koma yayikulu ili m'mphepete mwa nyanja, ngakhale kuti mulomo wa cormorant ndi wamphamvu, koma sungathe kupirira. Pali nthawi zina pomwe cormorant amatha kumeza tizilombo touluka, njoka kapena buluzi, koma izi ndizosowa. Cormorant ndi mbalame ya masana, nthawi zambiri amasaka kawiri pa tsiku, pomwe munthu m'modzi amadya pafupifupi magalamu 500 a nsomba, ndipo izi zimangokhala kusaka kamodzi, kilogalamu imodzi patsiku imapezeka, koma nthawi zina zowonjezerapo, chifukwa cha kususuka kwawo sanawakonde.

Kusaka nthawi zambiri kumachitika ndi achibale awo, amawedza nsomba pamadzi, ndi ma cormorants akuya. Ziphuphu zimasaka, zokha komanso m'matumba, zimangotsata nsomba zam'madzi ndikuziyendetsa m'madzi osaya, kwinaku zikupiza mapiko ake mokulira ndi madziwo, zikumuphwanya kale ndipo zikuchita nawo.

Chochititsa chidwi: cormorant kusintha chimbudzi, amatha kudya miyala yaying'ono.

Mbalame yofunda: malo okhalamo ndi zakudya

• Tiyenera kudziwa kuti ma cormorants ndi mbalame zokongola wosasamala chilengedwe chake. Chachikulu ndichakuti payenera kukhala dziwe pafupi, ndipo nyengo sizichita gawo lapadera. Chifukwa cha izi, ma cormorant amatha kupezeka kulikonse padziko lapansi, osati kokha kunyanja kapena kumtsinje, koma ngakhale m'malo omwe mumakhala madambo.
• Monga tanena kale, Chakudya chachikulu cha ma cormorants ndi nsomba (zazikulu zonse zazing'ono ndi zapakatikati - hering'i, sardine, capelin). Kuphatikiza apo, ma cormorants amatha kusaka njoka, nyama zazing'ono zam'madzi, tizilombo, achule ndi crustaceans. Ndipo kusintha njira zawo zopukusa chakudya, iwo kumeza miyala ing'onoing'ono.

Chakudya chachikulu

• Mbalame yolimba imeneyi imatha kudya theka la kilogalamu ya chakudya masana, yomwe, limodzi ndi kuchuluka kwa magulu awo, imasanduka vuto lalikulu chifukwa chakuchepetsa kwambiri kuchuluka kwa nsomba m'matupi amadzi.
• Anthu anazindikira luso la usodzi wa ma cormorants kwa nthawi yayitali ndipo anakopa iwo asodzi. Pachifukwa ichi, aku China ndi Japan adabwera ndi diver yapadera kuti adzaike pakhosi la anthu ena okhala ndi utoto mphete, osaloleza kumeza nsomba, ndipo amabwera ndi mwini wake - nthawi zina, mpaka 100 makilogalamu pa usodzi uliwonse.

Mawonekedwe a machitidwe ndi moyo wawo

Chithunzi: Black Cormorant

Cormorants, kupeza malo asodzi, adzabwereranso kumeneko. Chochititsa chidwi: cormorant amatha kusaka ndi kumakhala m'madzi am'nyanja ndi m'madzi oyera, chinthu chofunikira kwambiri kwa iwo ndi kupeza chisa mu dziwe. Mitundu yaying'ono ya mbalamezi imatha kukhala pamaboti, kukhala ndi mphamvu yayitali, chifukwa cha kukula kwake.
