Ondlunkulu - abameleli be-bird squad iningi, elibonakaliswa ngosayizi omncane, uqhwaku olunamandla nobuntu obunomsindo. Lezi zimpaphe azishiyi izindawo zazo zendabuko ngisho nasebusika. Futhi wonke wesihlanu ukholelwa ukuthi akhuthazelela noma yikuphi ukubanda, njengoba behlala ezinkanyezini futhi bengafudumala ndawonye. Kepha eqinisweni, ama-70% ondlunkulu bemindeni iqhwa. Isizathu salokhu amazinga okushisa aphansi.
Ngo-2018, engxenyeni yesibili kaFebhuwari, i-Arctic AnticyClone kanye nokuhlasela kwe-Ultrapolalalar kwafika engxenyeni yaseYurophu yaseRussia, eningizimu yeMpumalanga Ekude, ama-Urals naseSiberia. Ebusuku, izinga lokushisa lehliselwa ku-39 degrees nangaphansi. UMnyango Wezimo Eziphuthumayo ucele abantu ukuthi bangashiyi ekhaya ebusuku. Uma labo ababandayo ngokhahlo bayingozi kubantu, bese kuba yizilwane ezincane ngokufana kondlunkulu - kwakubulalayo.
Ngaphezu kwalokho, ukuvama kwamazinga okushisa anawo anawo-analomalous kwasusa lelo thuba ukuxhuma emasimini afudumele.
U-Alexander Shepel, udokotela we-ornithologist waseRussia ovela ku-perm, kanye nabantu abanomqondo ofanayo, amaseli we-perm avulelwe ukulandela ukunyakaza kwawo ngesikhathi esibandayo. Ngemuva kwesikhashana, i-tit yatholakala eCheboksary. Lokhu kufakazela umbono wokuthi ezimweni ezingezinhle, noma imvamisa izinyoni zobusika zishintsha okwesikhashana indawo yokuhlala.
Okufanayo kusebenza kondlunkulu, ngoba zombili izinhlobo zeqembu elilodwa futhi zinokuziphatha okufanayo. Kepha ngokusatshalaliswa kwamaqhwa abanzi, izinyoni zimane nje zintula izindawo zokundiza lapho ziphuma khona, ezazingenzeke ngo-2018 ngokufakazela ukufa kwabantu ngempaphe.
Ngaphezu kwalokho, isazi se-ornithologist saphawula ukuthi usuku olufushane lwasusa ithuba lokudla okugcwele okugcwele. Amandla anganele aholele ekutheni ondlunkulu bebuthakathaka futhi akazange akhiqize amandla anele okusinda ezimeni zokubanda okuhlala isikhathi eside.
Noma kunjalo, ngesikhathi esijwayelekile, izimpaphe zigcina ngokuzolile zidonsa amadigri angama-40 lapho kubanda kungekudala ngezinsuku ezifudumele nobusuku.
Kuhle futhi ukuphawula ukuthi i-metabolism esheshayo yisici esiyinhloko sazo zonke izimpande, zinosayizi omncane. Badinga ukudla okuningi ngenxa yezindleko ezibanzi zamandla. Kepha usuku olufushane olukhanyayo aluvumeli ondlunkulu ukuba badle izinga lansuku zonke bese beba buthaka.
Ngasikhathi sinye, isithwathwa esisheshayo, ukudla okudingayo. Ngakho-ke, abantu kufanele banake lezi zinyoni ezincane zasemadolobheni futhi bondla labo mabele, amabele nama-oats. Lezi zinhlamvu ziyisisekelo sokudla kwalolu hlobo lwefeka.
Ngakho-ke, ondlunkulu abakwazi ukubhekana nesikhathi eside sokuncipha kwamazinga okushisa. Isikhathi esifushane bayakwazi ukusinda, kepha kuphela ngosizo lomuntu.
