摘要

2019年5月，在南非中部自由邦省的一个农场大坝上，拍摄到了一些没有飞行毛的圆嘴鸭。虽然在非洲南部的东北部相当普遍，但这显然只是该次区域该物种换羽的第三次记录。

Knob-billed Duck Sarkidiornis melanotos moulting in the Free State

Some Knob-billed Ducks Sarkidiornis melanotos in flightless moult were photographed on a farm dam in the central Free State Province of South Africa in May 2019. Although fairly common in the north-eastern quarter of southern Africa, this is apparently only the third record of this species moulting in the sub-region.
