Vˇetˇsina kachen poch´

Jako kachny se t´eˇz obecnˇe oznaˇcuj´ı vˇsichni pt´aci z ˇceledi kachnovit´
ych, jsou-li
menˇs´ı neˇz husy nebo labutˇe, kachnou proto m˚
uˇzeme nazvat prakticky jak´

Podle zp˚
usobu obˇzivy se kachnovit´ı dˇel´ı na plovav´e a pot´apiv´e kachny: plovav´e kachny si hledaj´ı potravu v mˇelˇc´ıch vod´ach, pan´aˇckuj´ı“, hlavu maj´ı sice
