Below: The green wing speculum of grey duck. Mallards have orange legs and feet. They tend to stay in or near rushes at the edge of ponds and lakes and like other Anas species, feed by upending. The ducklings leave the nest as soon as the brood is dry, and accompany the female for about 7-9 weeks, but feed themselves from the outset. The Grey Duck is similar to a female mallard ducks in appearance, and most birds now show signs of hybridisation with mallards. Marchant, S.J. Finally got around to mounting my NZ Grey Duck that I got in 2012. Developed as a dual-purpose duck, but usually kept for ornamental purposes. The upper wing is brown, with the speculum (on the trailing edge of the inner wing) an iridescent green with a trailing narrow white band (and no anterior band). As a result of rapid decline, the grey duck Anas superciliosa superciliosa was elevated to 'nationally critical' from 'nationally endangered' on the 2008 New Zealand Threat Classification System. The best opportunity to view grey duck is in forested headwater catchments and away from human settlements (where mallards and hybrids occur), in Northland, West Coast (South Island) and Fiordland.
