This species was originally placed in the genus Anas. A molecular phylogenetic study published in 2009 showed that the genus contained members with different evolutionary ancestors – it was polyphyletic. The genus was split into four new genera. This species and four others were placed in the resurrected genus Mareca. |

| Identifying a Gadwall v Female Mallard Giles Diggle |
|||
About
Uploaded on Mar 8, 2008 I put this video together because I used to find it difficult to identify a gadwall amongst a flock of female mallards. Both the male and female gadwall have a white patch at the base of the hind wing. The female mallard has a blue patch in the same place. This is the easiest way to tell them apart particularly at a distance. Video was taken at Slimbridge WWT in March 2008. Edited in IMovie HD 6.0.4. Filmed on handheld Canon MV880X. |
