Adult Grey Teal, presumed parent of hybrid ducklings.
观察细节
1 presumed female Grey Teal paired with an immature male Chestnut Teal and with 3 advanced juveniles. It's likely that this is the same mixed pair that had a large number of hybrid chicks several weeks ago. If the same pair, then this could be at least a second brood; the previous brood appeared to be particularly vulnerable to predation from dogs on and off leash. If the same birds, the male Chestnut Teal was originally assumed to be immature as it appeared similar to the current photographed bird weeks ago when it was attending to a large brood of hatchlings. Adult male Chestnut Teal in the area have not apparently moulted to near-female appearance at this stage of the season.
