[92] [94] The ducklings are precocial and fully capable of swimming as soon as they hatch. [95] However, filial imprinting compels them to instinctively stay near the mother, not only for warmth and protection but also to learn about and remember their habitat as well as how and where to forage for food.

Like most waterfowl, hooded merganser hatchlings are precocial and usually leave the nest within 24 hours after they hatch; this is about long enough to accommodate synchronous hatching. Once they leave the nest, the young are capable of diving and foraging, but remain with the female for warmth and protection. [16]
The hen alone incubates the eggs for 22 to 24 days before they hatch. The precocial downy chicks are then led by the female to the nearest body of water, where they feed on dead insects on the water surface. The chicks fledge in 46 to 47 days after hatching, but stay with the female until she has completed moulting. [12]

The family Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These birds are adapted to an aquatic existence with webbed feet, bills which are flattened to a greater or lesser extent, and feathers that are excellent at shedding water due to special oils. Forty-five species have been recorded in Illinois.
The eggs hatch in about 24–29 days, [5] The downy ducklings are grey, with paler upperparts, [19] and a white band on the neck, [14] and weigh 22–38 g (0.78–1.34 oz) within a day of hatching. Like all ducklings, they are precocial and leave the nest after a day or so, but the parents protect them until they fledge around nine weeks later. [5]
