Idada elinamehlo amhlophe (i-Aythya nyroca) noma idada elinamehlo amhlophe elomndeni wedada, i-Anseriformes oda.
Izimpawu zangaphandle zokuntywila ngamehlo amhlophe.
Usayizi womzimba ucishe ube ngamasentimitha angama-42. Iphiko lamaphiko lingamasentimitha angama-63 - 67. Isisindo: 400 - 800 g. Idada elinamehlo amhlophe idada lokuntywila elilinganiselwe, likhudlwana kancane kunetiye enekhanda elibomvu ngokugqamile onsundu. Ezimpapheni zesilisa, intamo nesifuba kugqame kakhulu ngombala onsomi omncane. Ngaphezu kwalokho, kukhona indandatho emnyama entanyeni. Ingemuva, ngemuva kwentamo kumnyama-nsundu ngombala oluhlaza, umsila ongaphezulu unombala ofanayo. Isisu sicishe simhlophe qwa bese siphenduka sibe isifuba esimnyama. Isisu sinsundu ngemuva.
Isethembiso simhlophe qwa, sibonakala kahle lapho inyoni indiza. Imivimbo esezimpikweni nayo imhlophe, imvamisa ayibonakali lapho idada lisemanzini. Amehlo amhlophe. Insikazi inombala ofanayo wezimpaphe, kepha ayiqhathanisi kangako uma iqhathaniswa neyesilisa. Umthunzi onsundu ngokubomvu awukhanyi, ngaphandle kwe-metallic sheen. Umzimba ophezulu unombala onsundu. Umbala wesisu ushintsha kancane kancane kusuka kumbala omnyama esifubeni kuya kwithoni elula. Iris inombala obomvu ngokubomvu kumadada amancane nabesifazane. Kukhona "isibuko" esimhlophe kulo lonke iphiko. Isethembiso sowesifazane simhlophe qwa. Izitho ezimnyama ezimpunga. Owesilisa ovunule ekwindla ubukeka ngendlela efanayo nowesifazane, kodwa amehlo akhe amhlophe. Izinyoni ezincane zifana namadada amadala, kepha ziyehluka ngombala ongcolile, kwesinye isikhathi zinamabala amnyama ahlukahlukene. Idada elinamehlo amhlophe lihlala emanzini hhayi ngokujule kakhulu, njengamanye amadada, ngenkathi liphakamisa umsila walo phezulu. Ekusukeni emanzini kuphakama kalula.
Lalela izwi lokuntywila ngamehlo amhlophe.
Indawo yokuhlala ye-dive-eyed dive.
Ama-diving anamehlo amhlophe ahlala ikakhulukazi emizimbeni yamanzi eyisicaba, atholakala ezingwadule ezisemihlwitha nasemathafeni. Kuyaqabukela, ama-diving anamehlo amhlophe ahlangana ne-steppe. Bancamela ukuhlala emachibini anamanzi anomunyu namanzi amasha, bayama emfuleni i-deltas. Bahlala emathafeni agcwele izimila ezisondele emanzini: umhlanga, i-cattail, umhlanga. Izindawo ezinjalo zilula kakhulu ekudlekeni nasekuheheni amadada ngendlela yokuphila eyimfihlo. Ebusika, izinyoni zihlala eduze nogu lolwandle noma emizimbeni emikhulu emaphakathi nezwe enezimila eziningi ezintantayo.
Ukuzala nokufukama kwedada elinamehlo amhlophe.
Izidleke zamehlo amhlophe zidleke emanzini anamanzi angenasawoti angajulile amanzi acebile ngohlaza kanye nezinambuzane ezingenamgogodla. Lezi zinhlobo zamadada zodwa futhi zishade nenkathi eyodwa kuphela. Isikhathi sokuzalisa siguqulwa kakhulu uma kuqhathaniswa nesikhathi sokuzalisa ezinye izinhlobo zamadada. Amabili afika sekwedlule isikhathi futhi afika ezindaweni zokuzalela maphakathi no-Mashi kahle kakhulu. Izidleke zifihlwe emibhedeni yomhlanga.
Zitholakala ematsheni nasesihlahleni, kwesinye isikhathi ogwini lwedamu. Isidleke sabatshuzi abanamehlo amhlophe ezindlini zemisipha ezishiyiwe kanye nasemigodini yezihlahla. Kwesinye isikhathi amadada ahlala esidlekeni esincane, lapho kwenzeka izidleke ziseduze.
Izinto zokwakha eziyinhloko udoti wezitshalo, ulwelwesi luthambile.
Owesifazane ubeka amaqanda asuka kasithupha kuya kwayishumi nanhlanu anoshukela omhlophe noma obomvu, alinganisa u-4.8-6.3 x 3.4-4.3 cm. Idada kuphela elifukamela imvuthu izinsuku ezingama-24 - 28. Eyesilisa icasha ezimileni esiseduze nesidleke futhi isize ukushayela amachwane amadada ngemuva kokuvela kwamachwane. Iphinde ichithe ngesikhathi sokuzala kanye nensikazi. Abahlukahlukene abanamehlo amhlophe banamazinyane owodwa kuphela ngenkathi. Ngemuva kwezinsuku ezingama-55, amadada amancane aqala ukundiza ngokwawo. Zizala unyaka olandelayo. Ekupheleni kwehlobo, abatshuzi abanamehlo amhlophe babuthana ezikoleni ezincane bese bethuthela ogwini lolwandle iMedithera neCaspian, bese beya eningizimu-ntshonalanga ye-Asia.
Ukudla okunomsoco kokuntywila ngamehlo amhlophe.
Amadada anamehlo amhlophe ikakhulukazi amadada adla utshani. Badla imbewu nezitshalo zasemanzini eziqoqwe ngaphezulu echibini noma ogwini. Njengamanye amadada amaningi, afaka ukudla kwawo ngezinambuzane ezingenamgogodla, ezibanjwa khona phakathi echibini: izinambuzane nezibungu zazo, ama-crustaceans nama-molluscs.
Izici zokuziphatha kokuntywila ngamehlo amhlophe.
Ukuntywila ngamehlo amhlophe kusebenza kakhulu ekuseni nakusihlwa. Emini, amadada ngokuvamile aphumula ogwini noma emanzini. Ngokuvamile, baphila impilo eyimfihlo futhi eyimfihlo. Izinyoni zidla uhlaza lwasemanzini nolunamanzi amancane, ngakho-ke, ngisho nasendaweni eseduze, zihlala zinganakwa, okuqinisa umbono wokuthi abatshuzi abanamehlo amhlophe baqaphile kakhulu. Ebusika benza imigqa ebanzi evame ukuxubana nemihlambi yamadada ase-mallard.
Ukusabalala kwedada elinamehlo amhlophe.
Idada elinamehlo amhlophe linobubanzi obumibalabala e-Europe, Kazakhstan nase-Western Asia. Lezi zinhlobo zithathwa njengeziphelile ezindaweni eziningi zokuhlala. Kukhona ukubonwa kwamadada endiza enyakatho ezifundeni zaseningizimu naphakathi zetaiga. ERussia, kunomngcele osenyakatho owedlulele wendawo yokwakha isidleke yedada elinamehlo amhlophe. Eminyakeni eyi-10-15 edlule, indawo yokwabiwa kwalezi zinhlobo yehle kakhulu. Njengamanje, idada elinamehlo amhlophe lihlala esifundeni iLower Volga nasendaweni yase-Azov. Kutholakala eCiscaucasia, ezindaweni eziseningizimu yeSiberia.
Kusatshalaliswe eNyakatho Afrika nase-Eurasia. Le ndawo isuka eningizimu yeNhlonhlo Yase-Iberia iye empumalanga iye ezindaweni eziphezulu zoMfula Ophuzi.
Uhlala eKazakhstan naseMpumalanga Ephakathi naseMpumalanga Eseduze, e-Asia Ephakathi. Umngcele osenyakatho wokufaka izidleke uhluka kakhulu. Abahlukahlukene abanamehlo amhlophe basebusika ogwini lolwandle i-Azov, iCaspian, iBlack neMedithera. Zima emanzini angaphakathi nezwe e-Iran naseTurkey. Zondla ezindaweni ezishisayo zase-Afrika eseningizimu yeSahara nasemilonyeni yemifula ejulile yaseHindustan. Ekufudukeni, kuvela ama-diving anamehlo amhlophe ogwini olusentshonalanga loLwandle lweCaspian, futhi emazingeni okushisa aphansi ebusika ahlala ebusika.
Izinsongo endaweni yokuhlala ye-dive-eyed white.
Ingcuphe enkulu yokuba khona kwalolu hlobo lwedada wukulahleka kwamaxhaphozi. Ezindaweni zayo eziningi, uhla luyancipha. Kuvamise ukuzingelwa ngokungena budedengu, ngamehlo amhlophe. Ukuqothulwa okuqhubekayo kwezinyoni kuholela ekwehleni kwesibalo sabantu.
Isimo sokonga sedada elinamehlo amhlophe.
Idada elinamehlo amhlophe lingelesigaba sezinhlobo ezisongelwa umhlaba wonke, lifakwe kwiRed Book yaseRussia naseKazakhstan.
Lezi zinhlobo zisohlwini Olubomvu, olufakwe eSithasiselweni II seBonn Convention, esiqoshwe kuSithasiselo esivumelwaneni sezinyoni ezifudukayo eziphothulwe phakathi kweRussia neNdiya. Idada elinamehlo amhlophe livikelwe ezindaweni ezigcinwe eDagestan, e-Astrakhan, endaweni yokulondolozwa kwemvelo yaseManych-Gudilo. Ukuze kugcinwe izinhlobo zamadada ezingavamile, izindawo zokuvikela imvelo kufanele zenziwe ezindaweni zokuqongelela izinyoni emzileni wokufuduka nasezindaweni zobusika. Ngaphezu kwalokho, kubalulekile ukuvimbela ngokuphelele ukudutshulwa kwamadiphu angavamile emadamini lapho kudla khona izinyoni.
