When females begin incubation, the male abandons the female and clutch and forms flocks with other males. By mid-summer the molting process begins for the male. The male loses his flight feathers all at the same time. This means they cannot fly and are at high risk of predation. During this time they move into remote places that are full of tall reeds where they can hide. This molting process takes up to four weeks. The male will have a more drab appearance and look similar to the female but maintaining bill color.
"First photo was taken at North Tazewell (Clinch River) on March 14, 2015 (migration arrival). The second photo was taken at Burkes Garden (Gose Mill Pond) on June 27, 2015. Note: In the 2nd photo's lower row, the second duck from the left is an example of a male in full molt."
