Ingwenya yeNayile yisilwane abantu abebesihlonipha futhi besesaba ngasikhathi sinye kusukela ezikhathini zasendulo. Lesi silwane esihuquzelayo sasikhonzwa eGibhithe lasendulo futhi ukubizwa ngaso ngokuthi uLephiathan omubi kutholakala eBhayibhelini. Kungaba nzima esikhathini sethu ukuthola umuntu ongeke azi ukuthi ingwenya ibukeka kanjani, kepha hhayi wonke umuntu uyazi ukuthi siyini lesi silwani, ukuthi siphila impilo enjani, sidlani nokuthi sizala kanjani inzalo yaso.
Incazelo yengwenya yeNayile
Ingwenya yeNayile isilwane esinwabuzelayo esikhulu esingeso somndeni wezingwenya zeqiniso ezihlala e-Afrika futhi siyingxenye esemqoka yezindawo eziphila emanzini neziseduze nasemanzini lapho. Inkulu kunezinye izingwenya ngobukhulu futhi iyilungu lesibili ngobukhulu kulo mndeni ngemuva kwengwenya ehlanganisiwe.
Ukubukeka
Ingwenya yeNayile inomzimba weskwati oyifomethi eyelulwe kakhulu, ephenduka ibe ngumsila ojiyile futhi oqinile, uthinte ngasekugcineni... Ngaphezu kwalokho, ubude bomsila bungadlula ngisho nosayizi womzimba. Imilenze enamandla kakhulu efushanisiwe yalesi silwane esinwabuzelayo isakazeka kabanzi - ezinhlangothini zomzimba ezihlangene. Inhloko, uma ibukwa ngenhla, inesimo sesigaxa esisondela kancane ekugcineni kwesifonyo, umlomo mkhulu, unamazinyo amaningi abukhali, isibalo saso sonke esingaba ngama-68.
Kuyathakazelisa! Ezinganeni zezingwenya ezisanda kuchanyuselwa emaqandeni, ungabona ukuqina kwesikhumba ngaphambili kwesifonyo, okubukeka njengezinyo. Lolu phawu, olubizwa ngokuthi "izinyo lamaqanda", lusiza izilwane ezihuquzelayo ezizalanayo ukuba zingene phakathi kwamagobolondo azo futhi ziphume emaqandeni ngokushesha.
Umbala wezingwenya zeNayile uncike ebudaleni bawo: ama-juveniles amnyama - nsundu yomnqumo ngombala omnyama wesiphambano emzimbeni nasemsileni, kanti isisu saso sinombala ophuzi. Ngokukhula, isikhumba sezilwane ezihuquzelayo sibonakala sifiphala futhi umbala uba mncane - luhlaza okotshani ngombala omnyama, kepha hhayi owehlukile emzimbeni nasemsileni.
Isikhumba sengwenya siwurhabaxa, sinemigqa yeziqu ezibheke phezulu. Ngokungafani nezinye izilwane ezihuquzelayo, ingwenya yaseNayile ayincibiliki, ngoba isikhumba sayo sithambekele ekululekeni nasekukhuleni nesilwane uqobo.
Ubukhulu bengwenya yeNayile
Lesi yisona ngwenya enkulu kunazo zonke e-Afrika: ubude bomzimba onomsila emadodeni alesi silwane bungafinyelela kumamitha amahlanu nohhafu. Kepha, ezimweni eziningi, ingwenya yeNayile ayikwazi ukukhula ngaphezu kwamamitha amathathu ubude. Kukholakala ukuthi lezi zilwane ezihuquzelayo zikhula zisuka emamitheni amathathu kuye kwamane ubude, kuya ngobulili. Isisindo sengwenya yaseNayile naso singaba ngamakhilogremu ayi-116 kuye kwangama-300, kuye ngobulili nobudala bawo.
Kuyathakazelisa! Abanye abazingeli, kanye nezakhamizi zalezo zindawo lapho kuhlala izingwenya zaseNayile, bathi babone izilwane ezinwabuzelayo zalesi silwane, ubukhulu bazo obufinyelela kumamitha ayisikhombisa noma ngisho ayisishiyagalolunye. Kepha ngenxa yokuthi laba bantu abakwazi ukunikeza ubufakazi bokuhlangana kwabo nesilo esikhulu kangaka, izingwenya ezinkulu, ezingaphezulu kwamamitha amahlanu ukuphakama, manje zibhekwa njengezinganekwane noma ngisho nokusungulwa "kofakazi bokuzibonela".
Uhlamvu nendlela yokuphila
Ngaphansi kwezimo ezijwayelekile, izingwenya azizona izilwane ezikhuthele kakhulu.... Iningi labo, kusukela ekuseni kuze kuhlwe, lihlala elangeni osebeni lwamachibi, imihlathi ivuleke kakhulu, noma isemanzini, lapho isuka khona lapho kuqala ukushisa kwasemini. Nokho, ngezinsuku ezinamafu, lezi zilwane ezihuquzelayo zingahlala ogwini kuze kuhlwe. Izilwane ezihuquzelayo zichitha ubusuku zicwile emfuleni noma echibini.
Lesi silwane esihuquzelayo asikuthandi ukuhlala sodwa futhi, imvamisa, izingwenya zaseNayile zihlala emaqenjini amakhulu, ngalinye lazo lingabandakanya kusuka emashumini ambalwa kuya ezilwaneni ezingamakhulu amaningana ezilwane zalesi silwane. Kwesinye isikhathi zize zizingele ngephakethe, yize, imvamisa ingwenya iyazingela futhi ikhetha ukuzenzela yodwa. Izingwenya zeNayile zingacwila kalula futhi zibhukude ngaphansi kwamanzi, okusizwa yizici zomzimba: inhliziyo enamakamelo amane, njengezinyoni, nolwelwesi olucingayo, olubizwa nangokuthi ulwelwesi oluvikela amehlo esilwane lapho sicwiliswa emanzini.
Kuyathakazelisa! Amakhala nezindlebe zezingwenya zeNayile kunesici esisodwa esithakazelisa kakhulu: ziyavalwa ngenkathi isilwane esirhubuluzayo sitshuza. Izingwenya zeNayile ziyabhukuda ngenxa yomsila wazo onamandla, omise okwegwedla, kuyilapho izidladla, futhi noma kunjalo yizimvane zangemuva kuphela, ezihlonyiswe ulwelwesi, angavamile ukuzisebenzisa lapho ebhukuda.
Ukuphuma emhlabeni, lezi zilwane zingakhasa ngesisu, noma zihambe, ziphakamise imizimba yazo. Uma kufiswa noma kudingekile, izingwenya zaseNayile ziyakwazi nokugijima, kepha zikwenza njalo, kepha ziphishekela nje okungahle kube yisisulu somhlaba noma lapho zibalekela esinye isilwane noma imbangi ebanqobile. Izingwenya zaseNayile, yize zazinenkinga, zibekezelela ukuba khona kwezihlobo zazo eziseduze, kepha ezilwaneni zezinye izinhlobo, ngaphandle kwezimvubu, ezingathathi hlangothi nabo, banolaka olukhulu futhi bavikela indawo yabo ngokuhlasela abantu abangabazi, noma ngabe ukuthi zingeziphi izinhlobo.
Uma kwenzeka kuba nesimo sezulu esisongela ubukhona bazo, njengokushisa okukhulu, isomiso noma ukubanda okubandayo, izingwenya zaseNayile zingamba imithombo yokukhosela emhlabathini zilale lapho kubanda kuze kube imvelo yangaphandle ibuyela kokujwayelekile. Kepha zithathwa ngokwahlukana, izilwane ezihuquzelayo ezinkulu kakhulu, ziyakwazi ukuvuka phakathi nalesi sikhathi sobusika bese zikhasa ziphume ukuze zishiswe yilanga, futhi kwesinye isikhathi zize zizingele, ngemuva kwalokho zibuyela emgodini wazo bese zingena ebusika kuze kufike ukuphuma kwazo okulandelayo.
Phambilini, bekunenkolelo esabalele yokuthi ingwenya ibinobudlelwano obungashiwongo nezinye izinhlobo zezinyoni, ezisiza lesi silwane esihuquzelayo ukusula umlomo ngemilomo yaso, sikhiphe izingcezu zenyama ezinamathele phakathi kwamazinyo. Kepha ngenxa yokuthi ubufakazi obunjalo akukwazi ukubhekwa njengothembekile, lezi zindaba, njengezindaba zezingwenya ezinkulu ezingama-7-9 amamitha ubude, zithathwa njengezinto nje ezinganekwane. Ngaphezu kwalokho, kunzima ukusho ukuthi lezi zilwane ezahlukahlukene zingasebenzisana kangakanani nokuthi ubudlelwane bazo buyisivumelwano sangempela yini.
Kuyathakazelisa! Izingwenya zeNayile nezimvubu ezihlala emzimbeni ofanayo njengoba nazo zinobudlelwano obuthandekayo. Ukungathathi hlangothi okungashiwongo kumisiwe phakathi kwalezi zilwane, noma kunjalo, ngasinye asiphuthelwa yithuba lokusebenzisa indawo enjalo ephumelelayo ngezinhloso zazo.
Kwenzeka ukuthi izimvubu zabesifazane, zihambe isikhathi esithile kusukela ematholeni azo, ziwashiye eduze kwezingwenya, ngoba isilwane esihuquzelayo esinamazinyo, okungekho noyedwa kubadli bomhlaba onesibindi sokusondela kuso, singumvikeli ongcono kunabo bonke abantwana bazo. Ngakolunye uhlangothi, amawundlu wengwenya yeNayile, ngenkathi esencane futhi esengozini enkulu, nawo, lapho umama wabo engekho, angafuna ukuvikelwa ezimvubu, agibele emhlane wawo.
Ngokuphikisana nenkolelo evamile, izingwenya zikude nesimungulu: abantu abadala bangenza umsindo ofana nokubhonga kwenkunzi, futhi amawundlu amancane, asanda kuchanyuselwa emaqandeni, ingulube njengamaxoxo nokutshiyoza, njengoba kwenza izinyoni.
Ingwenya yeNayile ihlala isikhathi esingakanani
Njengezinye izilwane ezinwabuzelayo, izingwenya zaseNayile ziphila isikhathi eside ngokwanele: isikhathi esiphila kuzo yiminyaka engama-45, yize ezinye zalezi zilwane ezihuquzelayo ziphila kuze kube yiminyaka engama-80 noma ngaphezulu.
I-dimorphism yezocansi
Abesilisa balezi zinhlobo bacishe babe yingxenye yesithathu enkulu kunabesifazane, kuyilapho lezi zamuva zingaba zikhulu ngokwengeziwe ngenxa yokuthi ubukhulu bomzimba wabo bubonakala bukhulu esibelethweni. Ngokuphathelene nokufaka umbala, inani lezihlangu noma ukuma kwekhanda, bese kuthi ezingwazini zeNayile zabobulili obuhlukile bacishe bafane.
Izinhlobo zezingwenya zeNayile
Kuya ngokuthi izingwenya zaseNayile zihlala kuphi nezici zazo zangaphandle.
Ama-Zoologists ahlukanisa izinhlobo eziningana zalesi silwane esihuquzelayo:
- Ingwenya yaseMpumalanga Afrika.
- Ingwenya yaseNtshonalanga Afrika.
- Ingwenya yaseNingizimu Afrika.
- Ingwenya yaseMalagasy Nile.
- Ingwenya yase-Ethiopia yaseNayile.
- Ingwenya yaseKenya yeNile.
- Ingwenya yaseCentral Frican Nile.
Kuyathakazelisa! Ukuhlaziywa kwe-DNA okwenziwa ngonyaka we-2003 kukhombisile ukuthi abamele izinhlobonhlobo zezingwenya zaseNayile banokuhluka okuphawulekayo ngokwe-genotype. Lokhu kwanikeza ososayensi abathile isizathu sokuhlukanisa imiphakathi yezingwenya zaseNayile kusuka eMaphakathi naseNtshonalanga Afrika ibe yizinhlobo ezihlukile, ezibizwa ngokuthi ugwadule noma ingwenya yaseNtshonalanga Afrika.
Indawo yokuhlala
Ingwenya yeNayile - umhlali wezwekazi lase-Afrika... Ungahlangana naye kulo lonke elase-Afrika eseNingizimu yeSahara. Uhlala naseMadagascar nakwezinye iziqhingi ezincane ezisogwini lwe-tropical Africa. Njengoba igama lisho, ingwenya yoMfula ihlala eNayile, ngaphezu kwalokho, itholakala yonke indawo, kusukela kuma-rapids wesibili nangaphezulu.
Lesi silwane esinwabuzelayo sande kakhulu emazweni aseNingizimu naseMpumalanga ye-Afrika, okungukuthi, eKenya, e-Ethiopia, eZambia naseSomalia, lapho inkolo yezingwenya isathandwa khona namanje. Ezikhathini zangaphambili, lesi silwane esihuquzelayo sasihlala kude kakhulu nasenyakatho - endaweni yaseGibhithe nasePalestine, kepha asisekho lapho, ngoba sisanda kuqothulwa ngokuphelele kulezo zingxenye.
Ingwenya yeNayile ikhetha imifula, amachibi, amaxhaphozi, imihlume njengendawo yokuhlala, futhi lesi silwane esihuquzelayo singahlala emanzini ahlanzekile nasemanzini abilayo. Uzama ukuhlala hhayi ehlathini, kepha kwesinye isikhathi uzulazula echibini lehlathi.
Ukudla kwengwenya yeNayile
Ukudla kwengwenya yeNayile kwenzeka izinguquko ezinamandla kukho konke ukuphila kwalesi silwanyana esihuquzelayo. Amantshontsho angakhuli abe yimitha elilodwa adla kakhulu izinambuzane namanye ama-invertebrate amancane. Okucishe kube yingxenye yawo kukhona amabhungane ahlukahlukene, izingwenya ezincane ezikuthanda kakhulu ukuzidla. Ebusuku, amawundlu nawo angazingela ukhilikithi nojekamanzi, abawabamba otshanini obuminyene osebeni lwemizimba yamanzi.
Ngemuva kokuthi i-reptile ekhulayo ifinyelele usayizi wemitha elilodwa nohhafu, iqala ukuzingela izinkalankala neminenke, kepha lapho nje ikhula ibe ngamamitha amabili ubude, inani lama-invertebrate kwimenyu yalo liyancipha kakhulu. Kuphela e-Uganda kuphela, ngisho nezingwenya ezindala impela kuyaqabukela, kepha zisadla iminenke emikhulu nezinhlobonhlobo zezinkalankala zamanzi angenasawoti.
Inhlanzi ivela ekudleni kwengwenya encane yeNayile ngemuva kokukhula okungenani amamitha ayi-1.2, kepha ngasikhathi sinye iyaqhubeka nokudla izinambuzane ezingenamgogodla: izinambuzane ezinkulu, izinkalankala nezimvu ezifana neminenke.
Okubalulekile! Yizinhlanzi okuwukudla okuyinhloko kwentsha yalolu hlobo, futhi kwezinye izindawo, ingxenye enkulu, abantu abadala abangakafiki kubude bamamitha amathathu bayayondla.
Ngasikhathi sinye, isirhubuluzi sizama ukuzingela inhlanzi esilingana naso ngosayizi. Ingwenya enkulu ngeke ijahe izinhlanzi ezincane emfuleni, futhi, okokuqala, lokhu kungenxa yokuthi ihamba kakhulu kunesibonelo, ikakhulukazi i-catfish enkulu, ethanda ukudliwa yingwenya enkulu yeNayile.
Kepha kungalungile ukucabanga ukuthi izingwenya zaseNayile zidla amashumi amakhilogremu ezinhlanzi ngasikhathi sinye: izilwane ezihuquzelayo ezinokuhamba okuncane zidinga ukudla okuncane kakhulu kunezilwane ezinegazi elifudumele, ngakho-ke, isilwane esihuquzelayo esinesisindo esingaphansi kuka-120 kg, ngokwesilinganiso, sidla okuthile ngosuku. igremu yezinhlanzi ezingama-300. Ngenxa yokuthi kunezingwenya eziningi emifuleni yase-Afrika, kunomthetho wemvelo wenani lezinhlobo zezinhlanzi ezihlala emachibini afanayo, emifuleni nakweminye imizimba yamanzi njengalezi ezihuquzelayo, kodwa umonakalo omkhulu kubantu bawo awubangelwa.
Izingwenya nazo zingazingela izilwane eziphila ezweni nasemanzini nezinye izinhlobo zezilwane ezihuquzelayo... Ngasikhathi sinye, amaxoxo abantu abadala awadli, yize izilwane ezincane ezikhulayo zizidla ngokujabula. Futhi ezihuquzelayo, izingwenya zaseNayile zidla ngisho nezinyoka ezinobuthi, njengemamba emnyama. Izimfudu nezinye izibankwa ezinkulu ikakhulukazi, ezifana ne-Nile Monitor, nazo zidliwa yizilwane ezindala. Izingwenya ezincane nazo zizama ukuzingela izimfudu, kodwa ngenxa yokuthi kuze kube yiminyaka ethile ubudala azinawo amandla anele okuluma ngegobolondo lofudu, ukuzingela okunjalo akunakubizwa ngokuthi kuphumelele.
Kepha izinyoni ezikumenyu yezingwenya azivamile futhi, ngokujwayelekile, zakha kuphela u-10-15% wenani lokudla okuphelele okudliwe yisirhubuluzi. Ngokuyinhloko, izinyoni ziba yizisulu zezingwenya ngengozi, njengoba, ngokwesibonelo, kwenzeka ngezinkukhu ezincane ezisencane eziwela ngephutha esidlekeni zingene emanzini.
Abantu abadala abakhulu, osayizi wabo ongaphezu kwamamitha ayi-3.5, bakhetha ukuzingela izilwane ezincelisayo, ikakhulukazi ama-ungulates, eza emfuleni noma echibini ukuzophuza. Kepha nezilwane ezincane esezifike ebangeni elingamamitha ayi-1.5 sezingaqala ukuzingela izilwane ezincelisayo ezinobukhulu obukhulu kakhulu, njengezinkawu ezincane, izinhlobo ezincane zezinhlwathi, amagundane, ama-lagomorphs namalulwane. Kukhona okungajwayelekile njengama-pangolin kwimenyu yabo, abuye abizwe nangokuthi izibankwa, kepha awana lutho ngezilwane ezihuquzelayo. Izilwane ezincane ezinjengama-mongoose, ama-civet, nama-servals nazo zingaba yizisulu zengwenya ekhulayo.
Izingwenya ezindala zikhetha ukuzingela inyamazana emikhulu enjenge-Kudu antelope, i-wildebeest, i-eland, i-zebra, i-buffalo, indlulamithi, izingulube zasehlathini, futhi ikakhulukazi izinhlobo ezinkulu zingazingela obhejane nezindlovu ezisencane. Baze bazingele nezilwane eziyingozi ezifana namabhubesi, izingwe kanye nezingwe. Kaningi, ukudla kwesirhubuluzi kugcwaliswa ngenyama yamafisi nezinja zefisi, nazo eziba yizisulu zazo eduze nezindawo zokunisela.
Kubhekwe namacala ezingwenya zaseNayile ezidla imfuyo nabantu. Uma ukholelwa ezitatimendeni zabakhileyo ezigodini zase-Afrika, khona-ke abantu abaningana baqinisekile ukuthi bazodonswa futhi badliwe izingwenya kanye ngonyaka. Ekupheleni kwesihloko mayelana nokudla kwezilwane ezihuquzelayo zalolu hlobo, singangeza nokuthi izingwenya zaseNayile nazo zabonakala ekudleni kwabantu, lapho abantu abadala bedla amaqanda ezihlobo zabo noma amawundlu ohlobo lwabo, ngaphezu kwalokho, lesi silwane esihuquzelayo sikwazi ukudla imbangi eyabulawa empini.
Ukuzala nenzalo
Izingwenya zeNayile zifinyelela ekuvuthweni ngokocansi zineminyaka engaba yishumi ubudala... Kulokhu, owesilisa ubude bungamamitha ayi-2.5-3, kanti ubude besifazane buyimitha elingu-2-2.5. Isikhathi sokukhwelana salezi zilwane ezihuquzelayo ngokuvamile siwela ekupheleni konyaka, lapho kuqala isikhathi semvula e-Afrika. Ngalesi sikhathi, abesilisa bazama ukudonsela ukunaka kwabesifazane, okuthe lapho beshaya amanzi ngomlomo wabo, bahoxe futhi babhonge. Njengomthetho, owesifazane ukhetha umlingani omkhulu futhi onamandla kunabo bonke ngokuzala.
Ngemuva kokuthi “inenekazi” selizikhethele lona, imidlalo yokuqhamuka iyaqala, equkethe iqiniso lokuthi izingwenya ziyahlikihla ngezinhlangothi ezingezansi zesifonyo futhi zenze imisindo ekhetheke kakhulu ezenziwa yilezi ezihuquzelayo ngesikhathi sokuzala. Ngokukhwelana, okuthatha umzuzu owodwa noma emibili kuphela ngesikhathi, izigaxa zezilwane ezihuquzelayo zicwila phansi echibini, ukuze yonke inqubo yenzeke ngaphansi kwazo.
Ngemuva kwezinyanga ezimbili kudlulile ngemuva "kosuku" nendoda, insikazi imba umgodi ojule cishe u-50 cm esihlabathini esisogwini ebangeni elingamamitha amaningana ukusuka emanzini, lapho izalela khona amaqanda ayishumi nambili, angafani kakhulu nosayizi nokuma kwezikhukhukazi. Lapho inqubo yokubekela amaqanda isiqediwe, insikazi ifafaza isidleke ngesihlabathi bese izinyanga ezintathu, kuyilapho izingwenya ezincane zikhula ngaphakathi kwazo, iseduze futhi ivikela inzalo yesikhathi esizayo kunoma yiluphi usongo olungaba khona. Kuyenzeka ukuthi eyeduna ibuye ibe seduze sonke lesi sikhathi, ukuze izingwenya ezimbili zaseNayile ziqaphe i-clutch.
Okubalulekile! Ngesikhathi zilinde ukuvela kwenzalo, lezi zilwane ezihuquzelayo ziba nolaka ikakhulukazi futhi zishesha ngokushesha kunoma ngubani osondela ngokwanele esidlekeni sazo.
Kepha, phezu kwakho konke ukunakekelwa kwabazali, amaqanda amaningi abekelwayo ayanyamalala ngezizathu ezahlukahlukene, noma impilo yamathole akhula ngaphakathi kuwo ifa ngaphandle kwesizathu esizwakalayo, ukuze kuthi kuphela i-10% yezingwenya ezincane zesikhathi esizayo zisinde kuze kube zichanyuselwa.
Amantshontsho aphuma emaqandeni ngokwawo, asebenzise ukukhula okukhethekile okuqinile esigaxeni somlomo, aphula ngawo amagobolondo aqinile ngokwanele, noma abazali babo bayabasiza ukuphuma. Ukwenza lokhu, ingwenya yesifazane noma yesilisa yeNile ithatha iqanda liye emlonyeni wayo, lapho ingane ingeke iphume khona, bese liyikhama kancane ngomlomo wayo, ngenkathi libambe iqanda hhayi emazinyweni alo, kepha liphakathi kolwanga nolimi.
Uma konke kuhamba ngaphandle kwezinkinga futhi amawundlu wengwenya yeNile aphuma emaqandeni uqobo, aqala ukwenza imisindo efana ne-twitter. Ukuzwa ukukhala kwabo, umama umba isidleke, ngemuva kwalokho usiza amawundlu ukuthi afike emgodini ongajulile awukhethe kusengaphambili, lapho izingwenya ezincane zizokhula futhi zivuthwe khona: ukhombisa izingane indlela, ngasikhathi sinye ebavikela ezilwaneni ezingaphikisi ukudla izilwane ezihuquzelayo ezisanda kuzalwa, noma uma izingane zakhe, ngasizathu simbe, azikwazi ukwenza lokhu zodwa, uziyisa lapho, uzigcina ngokucophelela emilonyeni yazo.
Ubude bewundlu elisanda kuzalwa lengwenya yeNayile bucishe bube ngamasentimitha angama-30. Izingane zikhula ngokushesha okukhulu, kepha umama uyaqhubeka nokuzinakekela eminye iminyaka emibili. Uma izingwenya zesifazane eziningana zahlela izidleke eduze komunye nomunye, kamuva babambisana ekunakekeleni inzalo, bakha into efana nenkulisa yengwenya.
Kuyathakazelisa! Ubulili bezingwenya ezincane abunqunywa yizici zofuzo, kodwa ngamazinga okushisa esidlekeni ngenkathi izingane zikhula ngaphakathi kwamaqanda. Ngasikhathi sinye, ibanga lokushisa lapho kuzalwa khona izingwenya zaseNayile lincane kakhulu futhi lisuka kuma-31.7 kuye kuma-34.5 degrees.
Izitha zemvelo
Kungabonakala sengathi i-superpredator efana nengwenya yeNayile, ehlala endaweni ephakeme endaweni yayo, ayinakuba nezitha zemvelo, kepha lokhu akulona iqiniso ngokuphelele. Uma ingwenya endala ingazesaba nje izimvubu, lapho ngezikhathi ezithile iba nezimpi ezibulalayo, ngisho nomuntu, amawundlu akhe anezitha eziningi emvelweni. Ngasikhathi sinye, usongo olukhulu ekukhuleni kwezinto ezihuquzelayo luvela ezinyonini ezidla inyama: i-goliath herons, i-marabou nezinhlobo ezahlukahlukene zama-kites. Futhi izingwenya ezindala azikwenqeni ukudla amaqanda noma inzalo esanda kuchanyuselwa yizihlobo zazo.
Kuyenzeka ukuthi nezingwenya ezindala, ingasaphathwa eyezincane, ziba yizisulu zezilwane ezincelisayo, ezifana namabhubesi, izingwe, izimpisi nezinja zempisi. Ngaphezu kwalokho, uma abamele abakhulu bomndeni we-feline bekwazi ukubhekana nengwenya yeNayile yodwa, khona-ke izimpisi nezinja zempisi, ukuze zinqobe lesi silwane esihuquzelayo, zidinga ukusebenza ndawonye nawo wonke umhlambi.
Inani labantu kanye nesimo sezinhlobo
Ngenxa yokuthi ngeminyaka yo-1940 kuya kowe-1960 ingwenya yeNayile yayiyinto yokuzingelwa kwezemidlalo, inani layo, ebelilikhulu nje phambilini, lehlile ngokusobala, ukuze kwezinye izindawo kube nosongo lokuqothulwa kwalolu hlobo. Kodwa-ke, inani labantu bezingwenya zaseNayile likhulu ngokwanele ukuba liqokwe njengezinga elincane lokukhathazeka.
Ingwenya yaseNayile iyisilwane esikhulu kunazo zonke ezidla i-Afrika ezihlala emanzini ahlanzekile noma abilayo. Lesi silwane esihuquzelayo sinikeza isithombe sokuhamba kancane nokungagijimisi: empeleni, sikwazi ukuphosa umbani ngokushesha, futhi emhlabathini ingwenya ihamba ngokushesha okukhulu. Lesi silwane esihuquzelayo besatshwa futhi sihlonishwa abantu ekuqaleni kwempucuko, kepha inkolo yezingwenya isasinda kwezinye izindawo e-Afrika kuze kube namuhla: ngokwesibonelo, eBurkina Faso, ingwenya yaseNayile isabhekwa njengesilwane esingcwele, naseMadagascar lezi zilwane ezihuquzelayo zigcinwa emachibini akhethekile futhi ngezinsuku zamaholide ezenkolo bahlabela imfuyo kubo. EGibhithe lasendulo, izingwenya zazigcinwa ethempelini futhi ngemuva kokufa, njengofaro, zazingcwatshwa ngezihlonipho zasebukhosini emathuneni akhiwe ngokukhethekile.
