Ezindaweni ezinezikhukhula, ifika ngokufuduka, ngoSepthemba noma ngo-Okthoba, kepha ihlala lapho ngemuva kokuthi yomile. Kulezi zindawo, undiza ephansi futhi ahlole ngobuso bomhlaba, kwesinye isikhathi uhlala ezigxotsheni, ezinsikeni noma ezimpini. Ezindaweni ezinezintaba, bahlala kusuka olwandle kuya kumamitha ayi-2100. Azidli ngaphezu kwamamitha ayi-1500.
Ukusabalala kwe-piebald harrier

Izici zokuziphatha kwe-piebald harrier
Izithiyo eziboshiwe zivame ukuba zodwa.
Kodwa-ke, zichitha ubusuku ngamaqoqo amancane, kwesinye isikhathi nezinye izilwane ezihlobene nazo. Kwezinye izimo, nazo zindiza ndawonye lapho zithola indawo enokudla okuningi, nangesikhathi sokufuduka. Ngesikhathi sokukhwelana, bakhombisa izindiza eziyindilinga, zodwa noma ngababili. Iduna lenza ukugxuma okuyisidina lapho liqondiswa nguzakwethu ondizayo, lihambisana nokunyakaza ngokukhala okukhulu. Iphinde ifake nendiza yama-roller coaster engashintshi. Le mibhikisho yezindiza ibanjwa ikakhulukazi ekuqaleni kwenkathi yokuzalanisa. Kulesi sigaba, abesilisa bavame ukuphakela insikazi ukudla.
Ukuzalela i-piebald harrier
EManchuria naseKorea, inkathi yokuzalanisa izithiyo ze-piebald kusuka maphakathi noMeyi kuya ku-Agasti. E-Assam naseBurma, izinyoni bezilokhu zizalisana kusukela ngo-Ephreli. Ukukhwelana kwenzeka phansi, futhi ngaphambi nje kokubeka amaqanda esidlekeni. Isidleke esime njengeplati sakhiwe ngotshani, umhlanga nezinye izitshalo eziseduze kwamanzi. Unobubanzi obungu-40 kuye ku-50 cm ububanzi. Itholakala endaweni eyomile phakathi kwezihlahlana zomhlanga, umhlanga, utshani obude noma izihlahla eziphansi. Isidleke singasetshenziswa izinyoni ngezikhathi ezithile zokuzalela.
I-Clutch iqukethe amaqanda ama-4 noma ama-5, amhlophe noma aluhlaza anamabala amaningi ansundu. Iqanda ngalinye lizalelwa ngemuva kwamahora angama-48. I-clutch ifukanyelwa ikakhulukazi ngowesifazane, kepha uma ifa nganoma yisiphi isizathu, khona-ke owesilisa uzala inzalo uqobo.
Isikhathi sokufukamela singaphezu kwezinsuku ezingama-30.
Amachwane achamisela kungakapheli isonto elilodwa kanti iphuphu elidala likhulu kakhulu kunelincane. Eyeduna iletha ukudla ezigabeni zokuqala zokuchanyuselwa, bese zombili izinyoni zondla inzalo.
Amachwane aqala ukundiza maphakathi noJulayi, kodwa ahlala eduze kwesidleke isikhathi esithile, abazali bawo bawalethela ukudla. Izithiyo ezincane ze-piebald zizimela ekupheleni kuka-Agasti enyakatho nasekupheleni kukaJuni-Julayi emaphethelweni aseningizimu ebangeni. Umjikelezo wonke wentuthuko uhlala cishe izinsuku eziyi-100-110. Ekupheleni kuka-Agasti, izithiyo ze-piebald zibuthana emihlambini ngaphambi kokuhamba kwazo ekwindla, kepha azijabuleki ngalesi sikhathi kunezinye izithiyo.
Ukudla kwe-Piebald harrier
Ukudla kwe-piebald harrier kuncike ku:
- inkathi;
- isifunda;
- imikhuba yenyoni ngayinye.
Kodwa-ke, izilwane ezincelisayo ezincane (ikakhulukazi ama-shrews) yizisulu eziyinhloko.

Ngezikhathi ezithile badla izidumbu.
Izindlela zokuzingela ezisetshenziswa yi-piebald harrier ziyefana nezamanye amalungu ohlobo lwe-Circus. Inyoni edla inyama indiza iphansi ngenhla komhlaba, bese yehla ngokungazelelwe ibambe inyamazane. Ebusika, ukudla okuyinhloko ngamaxoxo ahlala emasimini elayisi. Ngentwasahlobo, i-piebald harrier ibamba ikakhulukazi izilwane ezincelisayo, izibankwa, izinyoni ezihamba phansi nezinambuzane. Ehlobo, izingela izinyoni eziningi ezilingana nemagpie noma igwababa.
Isimo sokonga se-piebald harrier
Indawo ephelele yokusatshalaliswa kwe-piebald harrier ilinganiselwa ukuthi iphakathi kuka-1.2 no-1.6 million square kilometres. Ezindaweni zokuhlala, izidleke zitholakala ebangeni elingamakhilomitha ayi-1 ukusuka komunye nomunye, okucishe kufane nobuningi bezidleke zezinye izilwane ezidla izinyoni. Inani lezinyoni lilinganiselwa ezinhlotsheni eziyizinkulungwane ezingamashumi ezinkulungwane. Indawo yokuhlala iPiebald harrier iyancipha ngenxa yokudonsa komhlaba nokuguqulwa komhlaba wezolimo. Kepha lolu hlobo lusakazeke kakhulu ngaphakathi kobubanzi balo. Inombolo yayo ayivezwa ezinsongweni ezinkulu, kepha ijwayele ukwehla, yize le nqubo ingenzeki ngokushesha okungadala ukukhathazeka phakathi kochwepheshe.
