Namhlanje siza kuthetha ngentaka edla inyama yosapho lwe-Accipitridae. Imalunga umgxobhozo. Igama layo lenzululwazi ngu i-circus aeruginosus kwaye ibonakala ngokuba nomsila omde kunye namaphiko abanzi kakhulu. Uzigcina zigcinwe kwimilo engu-V ngelixa esenza inqwelomoya elula kwimigama emide. Yaziwa kakhulu ngemigama emikhulu enokuyihamba ngexesha layo lokufuduka. Ngokuqhelekileyo, uninzi lolu hambo lwenziwa emanzini, ngokuchaseneyo neminye imizekelo yohlobo lwayo eyenza oko emhlabeni.
Kweli nqaku siza kukuxelela zonke iimpawu, ukuhanjiswa kunye nokutya kwe-marsh harrier.
Iimpawu eziphambili
Kolu hlobo umntu angabona uphawu i-dimorphism ngokwesondo eyenza kube lula ukwahlula inkunzi kwimazi. Kwaye kukuba imazi inethowuni emnyama emdaka enomhlwa kwaye inkulu kunendoda enombala omdaka okhanyayo. Njengoko ucwangcisa imigca yakho benza i-dihedral yokwandisa imigama abakwazi ukuyihamba. Ke zona iinkunzi, iintsiba zazo zibomvu bumdaka ngebala nemigca emthubi. Bagqama kakhulu kwisifuba sabo. Amagxa kunye nentloko inombala ongwevu-tyheli. Zombini iris kunye neziphelo zayo kunye nemilenze tyheli. Umlomo umnyama kwaye ungqindilili kwaye unemilo yehuka. Lo mlomo uhakiweyo usetyenziselwa ukubamba ixhoba lalo ngokulula.
Ngelixa ubhabha unokuyibona imibala emithathu yeharrier eyinkunzi emdaka, emnyama kunye nengwevu. Ngokuphathelele umfazi, Inombala wetshokolethi omdaka owenza umahluko emqaleni nakwindawo ephezulu yentloko. Kuzo zonke iziphelo kunye nenxalenye yendawo ephezulu yomqolo sibona umbala otyheli ngokubanzi. Indawo yamehlo ijika umbala omnyama kwaye yiyo eyenza iliso libonakale ngeso lenyama.
Zombini iinkunzi kunye neemazi zifana kakhulu nenqanaba lazo labadala xa ziselula. Nangona kunjalo, zinokuba mnyama kancinci ngasemva kunye nomhlwa otyheli okanye obomvu omdaka ngezantsi. Ekubeni ibonisa i-dimorphism yesini sifumana zonke ezi ntlobo phakathi kwendoda nebhinqa. Ukuba sihlalutya ubungakanani bazo zombini, siyabona ukuba iimazi zineesentimitha ezingama-45-50 ubude kunye namaphiko angama-111-122 yeesentimitha. Iinkunzi zinobude obuziisentimitha ezingama-45 kuphela kunye nobude bamaphiko phakathi kwama-97-109 eesentimitha. Oku kwenza ukuba inkunzi nemazi zibe neempawu ezahlukileyo.
Ubunzima nabo abulingani. Imazi inobunzima phakathi i 390-600 3030 grams kunye namadoda phakathi 290-390 grams kuphela.
Indawo yokusasazwa kunye nokuziphatha kwe-marsh harrier
Umntu uvelise iimpembelelo ezininzi ezingalunganga kuluntu lwe-marsh harrier ebangele ukuncipha kwabemi. Phakathi kweempembelelo ezimbi ezibangela owona monakalo mkhulu kubemi kukutshatyalaliswa kwendawo abahlala kuyo. Esi seso sizathu sokuba amazwe amaninzi afakwe kuluhlu lwezityalo ezikhuselweyo.
Zizilwanyana ezincinci ezihlala kwindawo ethi nangona ngexesha lasebusika iimazi zijongene nokususa amadoda kwindawo yokutya, ziphumla kunye emhlabeni xa ikwinqanaba lokuzala. Ayilohlobo lokuthululwa komhlaba kunye nezinye iintlobo kodwa ngakumbi phakathi kwazo. Nangona ibihamba imigama emide, inesantya esiphantsi kakhulu sokubhabha. Okufanayo kuya kubude. Luhlobo lwentaka olubhabha kwindawo ephantsi. Ukuthatha ithuba kwicala lomoya kwaye wonge amandla, inokubhabha ngokulula kwaye icwangciswe. Amadoda amadala anebhabhalaza elikhawulezayo nelikhawulezayo ukodlula amantshontsho okanye amabhinqa.
Ngaphandle kokubhabha, umgxobhozo unokutsiba kwaye uhambe. Ziyisebenzisa ukuze zikwazi ukushukuma ziphinde zifumane amaxhoba azo. Basenokuqokelela izinto ezahlukeneyo abazisebenzisayo ukufuduka okanye ukukhangela amantshontsho alahlekele kude kakhulu nendlwane.
Ngokumalunga nommandla wokusasazwa kunye nendawo yokuhlala, siyabona ukuba isuka eYurophu naseAfrika, kwingingqi yasemntla-ntshona, ukuya eAsia nakwindawo esemantla kuMbindi Mpuma. Indawo yokuhlala esoloko itshatyalaliswa yimigxobhozo yendalo kunye namathafa avulekileyo. Uninzi lwabo bonke abantu bayafuduka. Abanye bachitha ubusika kwiindawo ezinemozulu epholileyo kumzantsi nakwintshona yelizwekazi laseYurophu. Ngokuqhelekileyo bahlala kwiindawo ezivulekileyo ezifana namathafa, ama-savannahs kunye namasimi. Banokufumaneka nangona kunjalo ukuya kumlinganiselo omncinci, kwiindawo ezisentlango nakwimimandla yezolimo neyomlambo.
Kwiindawo ezininzi ehlala kuzo sinokubona iindawo ezinohlaza oluphantsi kodwa oluxinene kakhulu. Ngenxa yokwakheka kwazo, ukukwazi kwazo ukubhabha kunye nemikhwa yazo yokutya, akunakwenzeka ukuba bafumane yonke le mizekelo kwiindawo ezinamahlathi kunye neentaba. Indawo yokuhlala inokwahluka ngokuxhomekeke kwindawo efumaneka kuyo. Zinokufumaneka kwiindawo ezifana nemigxobhozo, zikhetha zonke ezo ndawo zityebileyo kwimoba, nangona zingafumaneka nakwiindawo ezinqabileyo zentlango.
Ukondliwa kwe-marsh harrier
Siza kubona izikhokelo zesondlo zolu hlobo lweentaka ngokuxhomekeke kwi-ecosystems. Ukutya kwayo kusekelwe ikakhulu kumasele, nangona nayo inokubamba izilwanyana ezincinci ezincancisayo, iinyoka, izinambuzane kunye namacilikishe. Ngaba irhamncwa elikhulu namantshontsho, amaqanda nezinye iintaka. Esi sesinye sezizathu zokuba le ntaka ingakwazi ukuhlala kwiindawo ezisezintabeni. Ubukhulu becala, yonke imithombo yawo yamandla ikwiindawo ezihlala emanzini. Olu hlobo luthatha ithuba lokubamba amaxhoba alo xa egula okanye enzakele. Ngale ndlela, benza ukubamba kube lula ngakumbi.
Inombono ophucukileyo wokubona, nangona isebenzisa iindlebe zayo. Inqwelomoya iyacotha kwaye iphantsi kodwa inokutyibilika kwindawo evulekileyo inamaphiko akwisimo esingu-V kunye nemilenze ejingayo. Xa ibona ixhoba Ukutyibilika kuguqula ukuntywila ngokukhawuleza ukuze ukwazi ukuyizingela.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga ne-marsh harrier kwiimpawu zayo.
