Madhadha ishiri. Iwo ane hukama nehanzi uye swans. Kungofanana neizvi, vanowanzogara pedyo nemvura, semuenzaniso, dziva. Chiri kushamisa pamadhadha muromo wakafara. Dhadha rerume rinonzi dhireki, dzimwe nguva zvakare dhireki. Mukadzi anongova dhadha.
Madhadha anotamba anotsvaka zvokudya zvawo mumvura, inonzi gudgeons. Vanotsvaga pasi pevhu kutsvaga zvipembenene zvemumvura, magakanje kana zvisaririra zvezvirimwa. Vanosveta mvura nemuromo wakashama voibudisa nemuromo wakashama. Kumucheto kwemuromo, lamellae kuita sefa. Lamellae mahwendefa nhete, matete anomira mumutsara.
Madhadha anonyura, kune rumwe rutivi, anonyatsonyura pasi. Vanogara ipapo kwehafu yeminiti kusvika kuminiti yakazara. Vanozviita kusvika pakadzika kwemamita imwe kusvika kumatatu. Vanodyawo magakanje nemarara ezvirimwa, pamwe nemamoluska akadai sehozhwa kana kuti squid diki.
Madhadha anozvara sei?
Munguva yekuberekesa, madhadha anogara ari maviri maviri. Zvisinei, vaviri vacho havagari mumakoloni, asi mumwe nomumwe. Hadzi inowanzovaka dendere. Inoshandisa matavi uye zvinhu zvakafanana. Pakupedzisira, inobvisa minhenga kubva mudumbu mayo yoishandisa kupetera dendere racho. Izvi zvinogadzira nzvimbo isina chinhu paganda rake inonzi "brood spot."
Madhiri haabereke. Kazhinji dzine mavara mazhinji muminhenga yadzo, hadzi dzinowanzoita grey kana shava, kuitira kuti vavengi vasadziwana zviri nyore pakuzvara. Zvakawanda zvinoenderana nekuti ndeupi rudzi rwedhadha rauri kutaura nezvaro. A mallard, semuenzaniso, ine clutch imwe chete pagore. Anotakura mazai anenge 7-16 mudumbu make panguva. Mazai edhadha akati kurei zvishoma pane mazai ehuku. Iyo yolk yakakura, asi ine shoma albumen.
Dhadha rinogara pamazai kuitira kuti varare pasi penzvimbo yevana. Nokuti ivo vanobva vabata ganda zvakananga, vane inodziya. Pashure pemavhiki mana, nhiyo dzinotanga kuchechenywa.
Madhadha anogona kusiya dendere rawo mushure memaawa mashoma. Ndiko kusaka vachinzi “zvikara”. Pashure peinenge mwedzi miviri vanogona kubhururuka. Asi vanogara nevanin'ina vavo naamai vavo kwemwedzi miviri. Boka rakadaro rinonzi "Schoof".
Madhadha ane vavengi vakawanda, kusanganisira mbira, makava, hedgehogs, martens, makonzo, imbwa, uye katsi. Dzinorwisa mhepo igora, gunguwo, gull, makondo akasiyana-siyana, peregrine falcon, uye zizi regondo. Otters, pike, nedzimwe hove dzinorwisa madhadha ari mumvura. Nokudaro, kubva kumhuka duku dzakawanda kazhinji, vashoma chete vanosara.
Sei vanhu vachichengeta madhadha?
Vanhu vazhinji vanofarira madhadha nekuti vanoawana akanaka uye vanofarira kuaona mupaki. Ndicho chikonzero nhasi tine marudzi akawanda edhadha akatanga kubva kune dzimwe nyika. Muenzaniso idhadha reMandarin, iro rinobva kuEast Asia.
Zvisinei, kungofanana nedzimwe shiri, madhadha anochengetwawo kuti adye nyama kana mazai awo. Kuti vaite izvi, vanhu vakatora mallard madhadha uye vakachengeta mhuka dzinovaraidza kubva kwavari. Izvozvo zvakaitika makore anenge 3,000 XNUMX apfuura.
Kupfuura zvose, madhadha anoberekerwa minhenga yawo. Dhadha pasi isarudzo yakakurumbira yekupfekedza mapiro. Minhenga yedhadha yaishandiswa kunyora kana miseve kuti ibhururuke yakananga mberi.
