Fourth week of September - Chestnut Teal

Continuing with the duck theme from last week (not much else going on when the place is flooded), Jaime and I came across this teal. It was swimming with an obvious Grey Teal, but was slightly bulkier, and much darker, especially around the head. Having grown up on the east coast where Grey Teals are the novelty, it is always nice to pick out the familiar Chestnut Teal from the west coast flocks.

Chestnut Teal - you can see a hint of green above the eye (female or immature male?)
