Gadwall (Mareca strepera)    Ducks, Geese and Waterfowl (Anatidae)
Knarand ~ Pato Friso ~ Snatterand
Gadwall 1402    (1 photos)
2010-02-14    Parque el Cedazo (Aguascalientes), Mexico

Subspecies: strepera
3 males and 1 female. The males are easy to recognize with the black rump, and the grayish brown general tone to the plumage. The female also has her own more grayish brown touch than female Mallard, and one can almost always be sure that a female accompanying one or more male Gadwall, also will be of this species - even though you don't see details well enough.

2012-11-12    Parque Héroes (Aguascalientes), Mexico

Subspecies: strepera
Female. Even when seen under difficult light conditions the female Gadwall is rather easy to distinguish from the female Mallard: It has a more elegantly shaped head and neck with a distinct grayish tone.

Subspecies: strepera
Female in flight. The white belly in combination with the white mirror reaching the trailing edge of the wing is characteristic for female Gadwall.

2014-03-02    Valle de las Garzas (Manzanillo), Mexico

Subspecies: strepera
Female. The white wing mirror is not visible here, but the slender head and bill with dark toward basis and orange toward the tip are. Not so common in Manzanillo.

Same as 1403. Female.

2014-08-15    Kalvebod Fælled, Denmark

Subspecies: strepera
Difficult to judge the sex on these birds because they are in eclipse plumage. On photo 3 the birds are lined up well for easier comparison. Here it looks like there is a clear difference between the 4 birds in front and the 2 at the rear end: The bill has much more dark on the 4 in front, thus indicating to me that they must be males. Also between the 3 photos the rufous upper wing patch are obvious on these birds. The last two birds therefore should be females, but the two between also look rather different, and it is possible the darker bird in front actually is a male, but then probably a young male because of the bill. I think it is safe to call the last bird a female - without deciding age.

Subspecies: strepera
Twilight mood. 3 with Mallard.


Gadwall 3363    (4 photos)
2020-04-06    Kongelundsområdet, Denmark

Male. Unmistakable and rather exquisite when you get to see it close by.

I suspect that it is a second calendar bird because of the pale mottling where the rump ought to be completely black, and I also suspect that the grayish base to the bill has something to do with age.

This bird paired with the female in 3363, and was a bit of a surprise to find them in the small pond next to Kalvebodhøj near Sydvestpynten. Not a place I would expect to find an 'exclusive' species like this. Less so because there are mallards in there too, and they probably prefer to have the pond for themselves.

2020-04-06    Kongelundsområdet, Denmark

Female. With male in 3363.

The distribution of orange and dark on the bill is characteristic for the species where Mallard normally shows a more irregular dark pattern. The characteristic white patch on the rear part of the gadwalls doesn't show on this bird, but with the more delicate build and the contrasting grayish head compared to the warm buff body you should still be able to suspect a gadwall when seeing a bird like this.
