Ama-Boobies (kusuka kuLat. Sula) - inyoni enkulu yasolwandle, ingeye-oda elifana nePelican, umndeni wakwa-Olushev. Okwamanje, kukhona ama-subspecies ayisithupha anamuhla nezibonelo ezimbalwa ezingasekho. Izinhlobo eziningi kakhulu: "amagannethi asenyakatho"Futhi"ama-boobies abbotยป.
Lezi zinyoni ezinhle zasolwandle zihlobene nama-phaeton, ama-cormorants nama-pelican. Ama-Boobies azizwa emuhle ebusweni bamanzi, kunokuba abe semhlabeni. Ungabuka ukuthi bakhukhuleka ngokuthula ebusweni bamanzi.
Izici nendawo yokuhlala yama-gannet
Inyoni ye-Gannet inobukhulu obukhulu: ubude bomzimba busuka ku-70 kuye ku-90 cm; isisindo - kusuka 0.7 kuya 1.5 kg; amaphiko afinyelela kumamitha amabili. Umzimba uvulekile, uhlanjululwe, intamo yinde, izimpiko zikhulu ngezimpaphe ezinhle.
Inhloko incane ngosayizi, uqhwaku luqinile, luhlangene, luhlaza ngombala. Amehlo mancane, ahamba, anombala ompunga. Endaweni ebunzini, ngaphansi kwesikhumba, kunamakhushini womoya wokunamathisela umzimba ngenkathi ungene emanzini.
Esithombeni i-boobie enyawo olubomvu
Umbono we-gannet uhlukaniswa ngokuqapha okukhethekile, kungumzimba we-binecular, okuvumela ukuthi unqume ngokunembile ibanga lelitshe nobukhulu balo. Le nyoni iphefumula ngomlomo wayo, njengoba ikhala seliminyene ngokuphelele. Ama-paw abekwe emuva kancane, amafushane, anombhede wewebhu. Izimpaphe ziminyene, ziqinile emzimbeni.
Umbala oyinhloko wama-gannet umnyama futhi umhlophe, kepha izithunzi zezimpaphe zingahluka kusuka ku-fawn kuya ku-brown. Konke kuncike kuma-subspecies kanye nobudala benyoni. Ngokuya ngohlobo, izidladla zinemibala eluhlaza okwesibhakabhaka noma ebomvu.
Okuhle kakhulu ngama-gannet ukuthi angamapheshana amahle kakhulu, abatshuzi kanye nababhukudi. Bacwila emanzini kusuka kubude obungamamitha ayi-10-100, ngaphansi kwamanzi - kuya ekujuleni kwamamitha angama-25. Ekufuneni inyamazane engaphezulu kobuso bamanzi, ingafinyelela isivinini esifinyelela ku-150 km / h.
Esithombeni, ama-gannets angena emanzini
Indawo ehlala izinyoni inwebeka ezindaweni ezishisayo nezisenkabazwe emhlabeni wonke. AmaGannet ahlala kuphela ezindaweni zasolwandle nasolwandle. Uthanda amabhishi anesihlabathi eside, iziqhingana ezishiyiwe, izindawo ezinamadwala kancane.
Amakoloni wezinyoni zasolwandle agcwalisa ngokuzithandela iziqhingi zasePacific, e-Atlantic, olwandle lwaseNdiya. Kuneziningi zazo ogwini lwaseMelika, eNingizimu Afrika naseziQhingini zaseGalapagos.
Isimo nendlela yokuphila ye-gannet
Ama-Boobies - ukuhlangana izinyoni zasolwandle, dala amaqembu ezinkulungwane ezingamashumi ezinkulungwane zabantu. Amanye ama-subspecies enza izindiza ezinde. Banomoya ozolile, bamatasa bafuna ukudla usuku lonke, ngokuqapha babheke inyamazane, bekhuphuka ngaphezu kwamanzi.
Esikhathini se-cape gannets
Emhlabathini, zihamba kabi, zifana nokuhamba kwedada. Kepha esibhakabhakeni, bazizwa sengathi bakulutho lwabo, bahlela indiza, bashaye amaphiko abo njengoba kudingeka, ngaphandle kokuchitha amandla futhi.
Bathanda "ukulenga" emisakazweni yomoya, babheke ngokucophelela ekujuleni kolwandle, bese ngokuzumayo, njengetshe, bawele emanzini. Abakwazi ukuchitha isikhathi esiningi ngaphansi kwamanzi, ngakho-ke baphonswa ebusweni bamanzi njengentanta.
Imvamisa ungabona umbono onjengokuthi ama-gannets azulazula ngaphezu kobuso ngaphandle kokunyakaza okukodwa. Unomqondo omuhle kakhulu we-aerodynamics, unekhono lokuzivumelanisa nezinqola zomoya futhi, ngokungathi kunjalo, "unamathela" kubo. Phezulu kwamanzi, inyoni yasolwandle ihlala isikhashana, ayihambi ibanga elide.
Ukudla kwe-Gannet
Ukudla okuyinhloko kwama-gannet olwandle, izinhlanzi nama-cephalopods. Bathanda i-squid kanye nabamele i-herring (ama-anchovies, ama-sardine, i-herring, i-sprat, i-gerbil). Ukuzingela inyoni akunzima, ngenxa yokubona kwayo okubukhali nangoqhwaku oluqinile. Kuyaphawuleka ukuthi le nyoni ibamba izinhlanzi hhayi ngesikhathi sokuntywila, kepha lapho ikhuphuka, ibona isisu senhlanzi.
Bayakujabulela ukubamba izinhlanzi ezindizayo ngaphezulu kolwandle; ziningi zangempela isithombe amagannethi... Zizingela ekuseni ngovivi noma kusihlwa kakhulu. Kwesinye isikhathi bangahlukanisa ukudla nge-algae encane egezwe osebeni ukuze bagcwalise izinqolobane zamavithamini nezinto ezincane.
Ngokuthakazelisayo, ama-gannet ngokuvamile ahambisana namahlengethwa nemikhomo lapho ejaha izikole zezinhlanzi. Lapho izikole zezinhlanzi zizinza ebusweni bamanzi, zihlaselwa izinyoni zasolwandle ezi-agile. Ngakho-ke, isikole sezinhlanzi cishe ngaso sonke isikhathi sibhujiswa.
Ukuzaliswa kanye nesikhathi sokuphila sama-gannet
Izinyoni zidla ogwini, eziqhingini ezinesihlabathi, izindawo ezinezinsalela ezincane kanye nokuzamazama okuncane. Isikhathi sokushela siwumbono omuhle, insikazi iphendula kakhulu kumbala wezidladla zesilisa kanye nesimo sokuzinaka kuyo. Ukukhwelana kwenzeka kanye ngonyaka.
Ama-gannet aseNyakatho ayakhathazeka komunye nomunye ngesikhathi sokukhwelana. Bathola indawo ecashile, bemi maqondana, baphakamise imilomo yabo bese bebawela. Isithombe siyancomeka, lo mbhangqwana ungama isikhathi eside unganyakazi.
Ama-boobies ezinyawo eziluhlaza okwesibhakabhaka baphakamise nemilomo yabo phezulu, kepha bashintshe inqubo ngokunyusa okunye kwezidladla. Lokhu kwenzelwa ukuthi insikazi ikwazi ukubona umbala ohlaza okwesibhakabhaka ogqamile wolwelwesi. Kungalesi sizathu lapho owesifazane enquma umlingani wakhe. Isibonelo, owesilisa onezidladla ezimpunga eziphaphathekile akasamthandi.
Esithombeni kukhona i-booby enyawo oluhlaza okwesibhakabhaka
Lo mbhangqwana uhlela ndawonye isidleke, okubalulekile ngamahlumela omile, izitshalo ezomisiwe noma ulwelwe. Inqubo yokwakha isatshalaliswa ngokuqinile: owesilisa uphatha impahla yokwakha, owesifazane uyayibeka phansi. Kuvamile ukuthi omakhelwane bantshontshelane izingxenye zesidleke.
UGannet wesifazane izalela amaqanda ayi-1 kuya kwayi-3, isikhathi sokuchanyuselwa sisukela ezinsukwini ezingama-38 kuye kwezingu-44. Bobabili abazali bayabandakanyeka kule nqubo, babamba ibamba kakhulu, ukuvimbela ukushintsha kwamazinga okushisa. Amaqanda afudunyezwa ngezidladla zawo, hhayi ngezimpaphe zawo. Amachwane azalwa enqunu ngokuphelele, ngosuku lwe-11 kuvele kuphela ukubhoboka.
Ama-boobies anezinyawo eziluhlaza okwesibhakabhaka achamusela amachwane kuphela. Isibonelo, amanye ama-subspecies adla kuphela anamandla kakhulu. Abantu abadala bondla amatshwele ngokudla okugaywe ngengxenye, kuthi kamuva kube nenhlanzi ephelele. Umbala wezinyoni ezincane unombala onsundu. Zishiya izidleke kusukela ezinyangeni ezintathu ubudala.
Esithombeni kunephuphu le-gannet bird
Emvelweni odokotela bazingelwa izinyoni ezidla inyama, kodwa lokhu akuvamile ukwenzeka, ngoba izidleke zisezindaweni okunzima ukufinyelela kuzo. Izingane ezingakwazi ukundiza zihlaselwa oshaka.
Inani elikhulu lodoti (i-guano) elishiyelwa o-gannet linenzuzo kwezolimo. IGuano icebile nge-phosphorus, edingeka kakhulu kwizitshalo ezikhulayo. Emvelweni wemvelo impilo ye-gannet uneminyaka engama-20-25 ubudala.
