It is obvious that Ferruginous Duck has a influence in the bird, but is it a genuine Ferruginous? When we saw it in 2010, we were convinced that it was a hybrid, due to the fact that the bird is very pale.
Ferruginous Duck or Hybrid, on this shot the bid seems to be almost Female Tufted Duck-colored, but note how the white vent seems to reach the side of the pump.
Ferruginous Duck or Hybrid, on this shot it really seems to be bright, and it also seems to have some greyish feathers in the back. Note also the bill, which has a black tip to a all dark greyish bill.
Ferruginous Duck or Hybrid, the headshape is steep in the forehead, and it has a rather big bill. On a genuine Ferruginoud the forehead is normally more rounded and the bill is slimmer.
Ferruginous Duck or Hybrid, again its a dull bird whit a large bill. Note the light marking along the bill.
Ferruginous Duck or Hybrid.
Ferruginous Duck or Hybrid, the wing stripe is in my opinion not all there, it seems to small, and in my opinion it is greyish in the primaries. The belly is however in favour of a genuine Ferruginous Duck, due to it´s clean white appearance.
