Grey Teal

This species is often considered a subspecies of Grey Teal (Anas gibberifrons). It does not present any sexual dimorphism. It is a small surface duck with a fairly light brown plumage with very pale cheeks, lower forehead, and front of the neck. The crown and back are a little darker brown than the sides. The eye is red and the bill is pale grey. The juveniles are similar, but paler and their eye is brown.
In flight, these birds present almost black wings with green reflections, a narrow white line in the back, and a wide white (triangular) band in the front. The undersides are white.
In Australia, the Grey Teal can be confused with a female Chestnut Teal (Anas castanea), but this last one does not have the cheeks and neck as pale and does not present any pale zone above the bill. In flight, the distinction is really not easy.
