Maccoa Duck

Oxyura maccoa

Large674 gWetland

As members of the stiff-tailed duck group, Maccoas are often found wading in the water with their tail feathers cocked upwards. As diving ducks, their bodies are specialized for being agile underwater swimmers and thus have sacrificed the characteristics that allow them to move well on land. As a result, their legs are set further back on their bodies which makes them awkward when walking out of water. Voice: When putting on their mating displays, males will often give out short whistles or will produce a prrrr'ing sound for 2 or 3 seconds. When feeling threatened, both males and females will emit low grunts.
