Details
Netta erythrophthalma (Southern Pochard) has two subspecies.
The gray-billed duck is slow and not afraid of people. Not good at tweeting, often in pairs or small groups of activity, sometimes also integrated hundreds of large groups. When resting, many groups stop in the beach and the island in the middle of the lake with water grass, and the flight is cumbersome and slow.
The breeding period of the gray-billed duck is April to June. Pairs are usually formed at the wintering ground, and nest building begins when they arrive at the breeding ground in mid-April. They usually nest on the island in the middle of the lake where there are many reeds and rushes, in the grass and dry reeds at the edge of the water, and sometimes in the dry reeds at the lake. It's usually well hidden. The nest is made of reed leaves and trichosis, and is padded with soft, fine grass and feathers. Each clutch lays 6-15 eggs, the eggs are light gray or pale green, the incubation period is 26-28 days, mainly by the female birds incubated eggs, but when the female birds leave the nest to feed, the male birds also undertake the task of incubating eggs, and the chicks can be hatched in early June.
