Koikoi

Koikoi ni ndege wakubwa wa jenasi Ardea katika familia ya Ardeidae wenye miguu mirefu na domo refu na nyembamba. Hupinda shingo yao wakiruka angani. Ndege hawa wana rangi nyeupe, kijivu na nyeusi. Spishi zenye rangi ya kahawiachekundu huitwa pondagundi pia. Spishi mbili nyeupe kabisa zinaitwa msuka na yangeyange. Zamani msuka ilikuwa imeainishwa ndani ya jenasi Egretta na yangeyange ndani ya jenasi Bubulcus. Kuna spishi nyingine za yangeyange ndani ya jenasi mbalimbali. Koikoi hupenda kula samaki lakini hula wanyama wadogo pia, kama vyura, mijusi, nyoka na panya. Hujenga matago yao kwa matawi juu ya miti. Jike huyataga mayai 2-6.
