Namuhla sizokhuluma ngenyoni edla inyama yomndeni wakwa-Accipitridae. Imayelana i-marsh harrier. Igama layo lesayensi ngu i-circus aeruginosus futhi ibonakala kakhulu ngokuba nomsila omude namaphiko abanzi kakhulu. Uwagcina emume ngendlela engu-V ngenkathi enza indiza elula emabangeni amade. Yaziwa kakhulu ngamabanga amakhulu engawahamba phakathi nenkathi yokufuduka kwayo. Ngokuvamile, iningi lalolu hambo lwenziwa emanzini, ngokuphambene nezinye izibonelo zohlobo lwayo ezenza kanjalo emhlabeni.
Kulesi sihloko sizokutshela zonke izici, ukusatshalaliswa kanye nokudla kwe-marsh harrier.
Izici eziyinhloko
Kulolu hlobo umuntu angabona uphawu i-dimorphism yocansi eyenza kube lula ukuhlukanisa owesilisa kowesifazane. Futhi ukuthi insikazi inethoni ensundu egqwalile emnyama futhi inkulu kuneyeduna enombala onsundu ngokukhanyayo. Njengoba uhlela imigqa yakho bakha i-dihedral ukwandisa amabanga abakwazi ukuwahamba. Ngokuqondene namaduna, izimpaphe zawo zinsundu ngokubomvu ezinemigqa ephuzi ngokuphaphathekile. Zigqama ikakhulukazi esifubeni. Amahlombe nekhanda kunombala ompunga-ophuzi. Kokubili iris namaphethelo nemilenze kuphuzi. Uqhwaku lumnyama futhi luwugqinsi futhi lunomumo wehhuku. Lo qhwaku oluboshwe lusetshenziselwa ukubamba inyamazane yayo kalula.
Ngenkathi undiza ungabona imibala emithathu yezimpawu ze-marsh harrier yesilisa, ensundu, emnyama kanye nempunga. Ngowesifazane, Inombala onsundu kashokoledi odala umehluko emphinjeni nasengxenyeni engenhla yekhanda. Kuwo wonke amaphethelo kanye nengxenye yesifunda somgogodla ongaphezulu sibona umbala ophuzi ojwayelekile. Indawo yamehlo ishintsha umbala omnyama futhi iyona eyenza iso libonakale ngeso lenyama.
Kokubili iduna nezinsikazi zifana kakhulu nesigaba sazo sabantu abadala lapho zisencane. Nokho, zingaba nsundu ngandlela thize ngemuva futhi zibe phuzi ngokugqwala noma zibe nsundu ngokubomvu ngezansi. Njengoba iveza i-dimorphism yocansi sithola zonke lezi zinhlobonhlobo phakathi kweduna nensikazi. Uma sihlaziya ubukhulu bakho bobabili, siyabona ukuthi ezinsikazi zinobude obungamasentimitha angama-45-50 namaphiko angama-111-122 amasentimitha. Abesilisa banobude obukhulu obungamasentimitha angama-45 kuphela futhi ububanzi bamaphiko buphakathi kwamasentimitha angama-97-109. Lokhu kwenza owesilisa nowesifazane babe nezici ezihlukene.
Isisindo naso asilingani. Insikazi ingakala phakathi amagremu angama-390-600 3030 kanti abesilisa baphakathi kuka-290-390 amagremu kuphela.
Indawo yokusabalalisa nokuziphatha kwe-marsh harrier
Umuntu udale imithelela eminingi engemihle kubantu be-marsh harrier okubangele ukwehla kwenani labantu. Phakathi kwemithelela emibi edala umonakalo omkhulu kubantu ukucekelwa phansi kwendawo abahlala kuyo. Lesi yisizathu esenza amazwe amaningi abalwe njengezilwane ezivikelwe.
Ziyizilwane ezincane ezihlala endaweni okuthi nakuba ebusika izinsikazi ziphethe ukuxosha abesilisa endaweni yokudla, baphumula ndawonye emhlabathini lapho kuyisiteji sokuzala. Akulona uhlobo lokuthulula indawo nezinye izinhlobo zezilwane kodwa kuningi phakathi kwazo. Nakuba ibihamba amabanga amade, inejubane eliphansi lokundiza. Okufanayo kuya ekuphakameni. Iwuhlobo lwenyoni endiza endaweni ephansi. Ukuze usebenzise ngokunenzuzo isiqondiso somoya futhi wonge amandla, ingashibilika kalula futhi iplane. Abesilisa abadala banokundiza okushesha nokushesha kakhulu kunentsha noma abesifazane.
Ngaphezu kokundiza, i-marsh harrier ingagxuma futhi ihambe. Ziyisebenzisa ukuze zikwazi ukunyakaza futhi zibuyise inyamazane yazo. Bangakwazi futhi ukuqoqa izinto ezihlukahlukene abazisebenzisayo ukufuduka noma ukufuna amatshwele adukele kude kakhulu nesidleke.
Mayelana nendawo yokusabalalisa nendawo yokuhlala, siyabona ukuthi isuka eYurophu nase-Afrika, esifundeni esisenyakatho-ntshonalanga, iye e-Asia nasenyakatho yeMpumalanga Ephakathi. Indawo yokuhlala ecekelwa phansi njalo amaxhaphozi emvelo namathafa avulekile. Iningi lazo zonke izakhamuzi ziyafuduka. Abanye bachitha ubusika ezindaweni ezipholile eningizimu nasentshonalanga yezwekazi laseYurophu. Ngokuvamile bahlala ezindaweni ezivulekile njengamathafa, ama-savannah namasimu. Bangatholakala nokho ngokwezinga elincane, ezindaweni eziwugwadule nasezindaweni zezolimo nezingasemfuleni.
Ezindaweni eziningi lapho lihlala khona singabona izindawo ezinohlaza oluphansi kodwa oluminyene kakhulu. Ngenxa yokwakheka kwazo, ikhono lazo lokundiza kanye nemikhuba yazo yokudla, mancane amathuba okuba izithole zonke lezi zibonelo ezindaweni ezinamahlathi nezintaba. Indawo yokuhlala ingahluka kuye ngendawo lapho itholakala khona. Zingatholakala ezindaweni ezifana namaxhaphozi, zincamela zonke lezo zindawo ezinomoba, nakuba zingatholakala nasezinkangala zezindawo eziwugwadule.
Ukondla i-marsh harrier
Sizobona iziqondiso zokudla okunomsoco zalolu hlobo lwenyoni kuye nge-ecosystem. Ukudla kwayo kusekelwe ikakhulukazi kumaxoxo, nakuba nayo ingabamba izilwane ezincelisayo ezincane, izinyoka, izinambuzane nezibankwa. Ingabe inyamazane enkulu namatshwele, amaqanda nezinye izinyoni. Lesi ngesinye sezizathu ezenza le nyoni ingakwazi ukuhlala ezindaweni ezinezintaba. Ikakhulukazi, yonke imithombo yawo yamandla isezindaweni ezihlala emanzini. Lolu hlobo luthatha ithuba lokubamba inyamazane yalo uma igula noma ilimele. Ngale ndlela, benza ukuthwebula kube lula.
Inombono othuthuke kakhulu wokubona, nakuba isebenzisa nezindlebe zayo. Indiza ihamba kancane futhi iphansi kodwa ingatshuza phezu komhlabathi ovulekile namaphiko anomumo ongu-V kanye nemilenze ilenga. Lapho ebona inyamazane i-glide ishintsha ibe ukutshuza okusheshayo ukuze ukwazi ukuyizingela.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana ne-marsh harrier ezicini zayo.
