When does Yuanyang molt?

Yuanyang molts from April to July in summer. According to relevant data, after long summer, male mandarin ducks will shed colorful feathers and replace them with elegant ones, just like female mandarin ducks. There is a process for male mandarin ducks to shed their feathers, first of all, the sail feathers on the side of their wings, then the white and blue epaulettes on the side, and finally the feather crown on their heads. It was not until mid-July that the male mandarin ducks completely faded their gorgeous costumes. Yuanyang: Yuanyang refers to male birds and Yuanyang refers to female birds, so Yuanyang is a compound word. It is a medium-sized suborder duck, ranging in size from mallard duck to green-winged duck, with a body length of 38 to 45 cm and a weight of about 0.5 kg. Hermaphrodite, with red beak and orange feet, bright and gorgeous feathers, gorgeous crown feathers on her head, broad white eyebrows behind her eyes, and a pair of chestnut yellow fan-shaped upright feathers on her wings, which stand on her back like sails, are very strange and eye-catching and easy to identify in the wild. The female bird's mouth is black, her feet are orange, her head and upper body are taupe, her eyes are white, and there is a thin white eyebrow pattern behind her, which is also eye-catching and unique.
