Nemapuranga ane simba uye nechigamba chakareba, dhaka tufted yakasiyana. Izvozvi shiri dzinogona kuva dzakaoma kuziva zvakanaka munzvimbo dzakasiyana siyana, zvisinei, nekuda kwehuwandu hwehuwandu hwakawanda nemabhasi akafanana. Nyeredzi dzinodzidza mamwe mashoko pamusoro pebhuru iri reEurasia dzichakwanisa kuzvicherechedza nekuzviona zviri nyore.

Vanhurume vane glossy black allover kunze kwekusiyanisa, zvakanyatsopenya-mavara machena uye mimba chena, uye mushure unogona kuoneka wakachena kupfuura wakatsvuka muvhenekera. Musoro nemutsipa zvinogona kuratidza chivara chepepuru chakasviba kana chemavara mukati mezuva rakajeka. Madzimai ari madema-grey-grey yakazara nechisimba chekushambidza kana kusina kuvhara pamakona, uye zvipfeko zvepfeko zvinopenya nejeri streaking. Madzimai ane shoma shoma shomanana kupfuura varume, uye anogona kuratidza chidimbu checheche chiduku kwazvo pasi pebhadharo, kunyange izvi zvisingaonekwi nguva dzose. Musana unowanzosviba kupfuura wepasi. Pamusoro pemadzimai maviri, maziso ari akajeka endarama, uye makumbo uye tsoka dzakasvibiswa zvine grey-dema.
  
  Vatongi vakafanana nevakadzi vakuru, asi vane zvishoma zvakasiyana uye greyish flanks.

Zvokudya : Mvura yakadzika, amphibians, crustaceans, mbeu, mollusks, zviyo, zvipembenene zvemvura ( Ona: Omnivorous )

Habitat uye Kutama:

Izvi zvinokurudzira madhavhi anosarudza miviri yakadzika yemvura yakadai semakungwa, anonoka-kufamba nenzizi uye zvose zvisikwa uye zvigadziriswe zvidhina. Zvinogonawo kuwanika mumapaki emaguta apo mazamu akanaka kana makungwa aripo.

Mhuru dzinoshandiswa dzinosarudza mvura yakachena, asi inowanikwa kakawanda mumhenderekedzo yegungwa, nzvimbo dzepamusoro kana kuti mvura yakadzika yemakungwa muchando.

Aya matongo anowanikwa gore rose kumadokero kweEurope, kusanganisira United Kingdom. Muzhizha, rutivi rwavo rwokubereka runoenderera kuIceland, Scandinavia uye muRussia yose. Muchando, vanoenda kumaodzanyemba kweEurope nekuchamhembe kweAfrica kusanganisira Nile River valley. Kumabvazuva, nguva yavo yechando inotangira kubva kuMiddle East kuburikidza neIndia kusvika kumabvazuva kweChina neJapan. Izvo zvizhinji zvakanyanya pamhenderekedzo yeItaly, Gungwa reCaspian uye nzvimbo dzakadaro.

Kunyange zvazvo madata aya asingawanzoonekwi mune zvakawanda zveNorth America, nhamba shoma dzinosvika kumadokero kweAlaska gore negore. Maonero ekuona maitiro anogona kunyorwa pamwe chete kuPacific neAlantic kumadokero kwegungwa, kunyanya munguva yechando, uye zvisingaoneki zvisizvo zvinowanikwawo muGreat Lakes.

Vocalizations:

Aya madhanza kazhinji anonyarara, asi ane mhete dzinokurudzira, kuderera kunokamba uye kunyorera mashezha sechikamu chezvemabhuku avo.

Maitiro:

Mhuru dzakasvibirira dzakasiyana-siyana, dzichienda zvakadzika mamita makumi maviri pasi pemvura pamusoro pemvura sezvavanodha. Vanogona kunge vakanyatsogadzirisa mushure mekuberekwa kwemwaka, uye kuungana mumapoka makuru kwazvo ayo angave akavhenganiswa nemamwe mabhasi ekufambisa, zvikurukuru scaups uye mabhendi ane mitsetse.

Kana zvichishamisika, dzichabva pamvura nokukurumidza, dzichimhanya pfupi pamwe chete nepamusoro pepamusoro kuti dziwane nguva yakakwana yekuputika kwemhepo.

Kubereka:

Dhakwai madhanhi ari oga uye anowirirana muchidimbu kuratidzirana kunosanganisira kuvhara musoro uye kubvumirana musangano kubhadhara. Mukadzi anovaka chando chisina kudzika kana pasi pechidziro chine uswa, kuchiputira pasi. Dendere rinowanzomira pasi pegwenzi kana uswa hwakasvibirira hwekukanganiswa. Mazai aya akafanana nemasvondo uye anotarisa kubva kumucheka wakajeka kusvika kune maronda machena kana kuti machena, uye kune mazai 7-12 mumhuri imwe neimwe.

Mukadzi wacho anobata mazai kwemazuva 25-29. Mushure mokunge mapeji avhuvhuta, vanogona kubva kubva mudendere nokukurumidza uye vanotanga kumhanya vachikanda mukati maawa 48. Vabereki vaviri vanotungamirira uye vanochengetedza ducklings, izvo zvichatora rwendo rwavo rwokutanga mumazuva 50-55 akare.

Vakomana vaduku vanamata vanogara nevabereki vavo kwemazuva makumi mapfumbamwe kana vachikura.

Aya madhawi anowanzogadzirisa nemhando dzakasiyana-siyana, kusanganisira scaups makuru, scaups maduku uye mabhendi ane mitsetse. Kupera zvishoma kushandiswa kwehuwandu kwakave kwakanyorerwawo nevarwi vemapurisa nevarlards.

Kukwezva Tufted Dhanki:

Kunyange zvazvo matata aya asiri mhenderekedzo yemashure, anogona kukwezva kune nzvimbo dzakakodzera dzine nzvimbo yakawanda yemvura yakadzika yekudya zvakakwana. Kuchengetedza nzvimbo iyo inokosha pakukwezva madata aya.

Kuchengetedza:

Ava matata akapararira uye akawanda. Mune imwe nzvimbo nzvimbo dzazvo dziri kuwedzera nekuda kwejecha nematombo ematombo anovaka zvigadziri zvinowedzera sevakanaka. Aya madhanhi anotengesa mafuta uye zvimwe zvinokonzera tsvina yemakemikari, zvisinei, uye zvinogona kunge zvakakonzerwa zvikuru neAvian influenza . Mune dzimwe nyika, zvikurukuru Danish, Italy neIrish, madhadha akachengetwa semutambo wemarudzi ekuchengetwa kwakarongeka .

Nyeredzi dzakafanana:

• Ring-Necked Dhaka ( Aythya collaris )
• Greater Scaup ( Aythya marila )
• Zvishoma Zvishoma ( Aythya affinis )
