Ukutshuza ngeBird Baer (i-Aythya baeri) kungokomndeni wedada, i-anseriformes oda.
Izimpawu zangaphandle zokutshuza kukaBerov.
Idada le-Baer lilinganisa ngo-41-46 cm.Lendoda ihlukaniswa kalula nezinye izinhlobo ezihlobene nekhanda layo elimnyama, ingxenye engenhla entanyeni nasemhlane enombala onsundu ngokubomvu, amehlo amhlophe nezinhlangothi ezimhlophe. Endizeni, iphethini ebonakalayo iyabonakala, njengaleyo yedada elinamehlo amhlophe (A. nyroca), kodwa umbala omhlophe wezimpaphe phezulu awudluli kuze kube manje kuzimpaphe zangaphandle. Iduna elingaphandle kwenkathi yokuzalanisa lifana nensikazi, kepha ligcina amehlo amhlophe
Owesifazane uhlukaniswa yikhanda elimnyama elibusayo eliqhathanisa nemibala entekenteke esinsundu kanye nezimpaphe ezimhlophe, ezihlukanisa kakhulu lezi zinhlobo ezinhlotsheni ezifanayo A. nyroca no-A. fuligula. Ngaphandle, ama-dives amancane afana nensikazi, kepha ahlukaniswa ngumthunzi we-chestnut wezimpaphe, umqhele omnyama ekhanda nomhlane omnyama entanyeni ngaphandle kokubekwa okucacile kwamabala.
Lalela izwi likaBarov dive.
Ukusabalala kokutshuza kukaBarov.
Ukuntywila kweBaer kusatshalaliswa ezitsheni zase-Ussuri nase-Amur eRussia nasenyakatho-mpumalanga yeChina. Izindawo zobusika zitholakala empumalanga naseningizimu yeChina, eNdiya, eBangladesh naseMyanmar. Izinyoni azivamile kakhulu eJapan, eNyakatho naseNingizimu Korea. Futhi naseHong Kong, eTaiwan, eNepal (okuluhlobo olungajwayelekile kakhulu), eBhutan, Thailand, Laos, Vietnam. Lezi zinhlobo zezihambi ezingavamile eMongolia futhi isivakashi esingavamile kakhulu ePhilippines.
Nciphisa isibalo sokudonsela phansi kukaBerov.
Ukuncishiswa kwendawo yedada likaBerov kwaqoshwa eChina ngenxa yesomiso esathatha isikhathi eside ezindaweni zokwakha izidleke. Ngo-2012, amarekhodi okuzalanisa kwalezi zinhlobo awazange enziwe ezingxenyeni eziyinhloko zebanga enyakatho-mpumalanga yeChina naseRussia engomakhelwane. Imibiko yakamuva ikhombisa ukuthi izinhlobo zedada eSifundazweni saseHebei futhi naseSifundazweni SaseShandong, eChina (idatha ka-2014). Abantu ababili babhekwe ebusika buka-2012-2013 eChina naseNingizimu Korea, mhlawumbe izinyoni zokuqala zasebusika. Abantu abangama-65 sebebonke, kubalwa nabesilisa abangama-45, babeyakha izidleke eChina ngo-Agasti 2014.
Owesifazane oyedwa wabonwa amasonto ambalwa eMuravyevsky Park eRussia ngoJulayi 2013, kodwa abukho ubufakazi obuqondile bokuthi kwakhiwa isidleke. Ukwehla okucijile nokuncipha kwenzekile ebusika bobusika bezinhlobo noma yikuphi ngaphandle kwezwekazi iChina, kufaka phakathi ukulahleka kwabantu ngasemfuleni iYangtze River Basin kanye neLake Anhui eChina naseBaichuan eWethan Wetlands.
Ngesikhathi sasebusika sika-2012-2013, kwakucishe kube nezinyoni ezingama-45 (ubuncane abangama-26) eChina, kubalwa nezindawo ezihlasela izikhukhula zeCentral and Lower Yangtze. Izindawo eziningana ezibalulekile zirekhodwe eBangladesh naseMyanmar. NgoDisemba 2014, ama-Baer dives angama-84 abonwa eThaipei Lake esifundazweni saseShandong. Linciphe kakhulu inani lezinyoni ezihamba ngasogwini lweSifundazwe saseHebei, eChina. Isibalo sabantu sokudilika kweBarov manje kungenzeka sibe ngaphansi kwabantu abayi-1000.
Indawo yokuhlala iBarov dive.
Ama-Baer dives ahlala azungeze amachibi anezimila ezicebile zasemanzini otshanini obuminyene noma kumaqhubu agcwele amanzi ezimfundeni zezihlahla. Esifundazweni saseLiaoning eChina, zivame ukutholakala ezindaweni ezingamaxhaphozi ezisogwini ezinotshani obukhulu noma emifuleni nasemizimbeni yamanzi ezungezwe amahlathi. Zakha izidleke emhumeni noma ngaphansi kwezihlahla, kwesinye isikhathi eziqhingini ezintantayo zohlaza olukhukhulekile, kaningi phakathi kwamagatsha esihlahla. Ebusika zimisa emachibini anamanzi angenasawoti nasemachibini.
Izizathu zokwehla kwenani le-Baer dive.
Ngokwemvelo, kube nokuncipha kwenani labantu okushesha ngokweqile ezizukulwaneni ezintathu ezedlule, ngokususelwa enanini lezinyoni ezirekhodwe ezindaweni zobusika, ezindaweni zokwakha izidleke nasemizileni yokufuduka.
Izizathu zokwehla aziqondakali kahle, ukuzingela nokucekelwa phansi kwamaxhaphozi ezindaweni zokuzalisa, ubusika nezindawo zokudla zokudilika yizona zizathu zokuncipha kwenani lezinyoni. Uma ukwehla kwesibalo sezinyoni kuqhubeka ngejubane elinjalo, khona-ke ngokuzayo lolu hlobo lunesibikezelo esidumazayo.
Kwezinye izimo, i-Baer dives ishiya izindawo ezazibalulekile zokusatshalaliswa ngenxa yamazinga aphansi amanzi noma ukoma okuphelele kwemizimba yamanzi, isimo esinjalo siyabonakala kubantu abahlala ebusika eBaikwang emaxhaphozini aseWuhan.
IMarshes ePhilippines, lapho kutholakala khona lolu hlobo lokuntywila ebusika, isengozini esheshayo yokuguqulwa kwendawo.
Ukuthuthukiswa kwezemidlalo yezokuvakasha nezokungcebeleka kubeka engcupheni izinhlobo zezilwane kwezinye izindawo ezinabantu abaningi. Ukuguqulwa kwezindawo ezingamaxhaphozi ngezinjongo zezolimo nokusatshalaliswa kwezitshalo zerayisi nakho kuyizinsongo ezinkulu ebukhoneni bezinhlobo. Kunemibiko yezinga eliphezulu lokufa kwabantu eBaer ngenxa yokuzingela, kuhlanganisa nombiko ngokudutshulwa kwabantu ababalelwa ku-3 000. Kepha imininingwane, ngokusobala, ihaba, ngoba leli nani lifaka ezinye izinhlobo zamadada adutshuliwe. Amacala okuzingela esebenzisa izingibe ezinoshevu aqoshwe ezindaweni zobusika zokuntywila kweBaer eBangladesh. Ukuhlanganiswa nezinye izinhlobo ezihlobene nakho kungaba yingozi.
Isimo sokongiwa kweBarov dive.
Idada iBaer libhekwa njengezilwane ezisengozini yokuqothulwa njengoba libhekene nokwehla okukhulu kwenani labantu, zombili ezindaweni zokwakha izidleke nasebusika. Kungenzeka ukuthi ayikho noma incane kakhulu ezindaweni zayo zangaphambili zokuzalanisa nobusika. Ukuntywila kwe-Baer kuku-CMS kuSithasiselo II. Lezi zinhlobo zivikelwe eRussia, eMongolia naseChina. Izindawo eziningi kumenyezelwe njengezindawo ezivikelekile futhi zitholakala ezindaweni ezivikelwe, ezibandakanya iDaurskoye, iKhanka neBolon Lake (iRussia), iSanjiang neXianghai (China), iMai (Hong Kong), iKosi (Nepal), neTale Noi (Thailand). Ukutshuza emanzini kuvame ukuzala kalula lapho kuthunjwa, kepha zimbalwa kakhulu emaphoyiseni.
Izinyathelo zokongiwa eziphakanyisiwe zifaka phakathi: ukuhlola ukusatshalaliswa kwe-Baer dive, izici nokuzalanisa nokondla. Ukusungulwa kwezindawo ezivikelwe nokuzalaniswa kwabathunjwa. Vikela izinyoni ezindaweni zokwakha izidleke, kufaka phakathi ukuhlinzeka ngokudla okwengeziwe nokuvikelwa kwesidleke. Ukuhlola okwengeziwe ngesikhathi sonyaka wokuzalela kuyadingeka naseMuravyevsky Park eTseisko-Bureinskaya Plain eRussia Far East ukuze kuqondwe ukuthi ngabe le ndawo ikulungele yini ukuzalela izidleke zezinhlobo. Nweba indawo yesiqiwu esiseduze neLake Khanka (Russia). Kuyadingeka ukumemezela i-Xianghai Nature Reserve (i-China) indawo engayi ndawo ngesikhathi sokuzalela. Lawula ukuzingelwa kwazo zonke izinhlobo zomndeni wedada eChina.
