These birds are migratory.

Mallards are preyed upon by various predators, such as crows, foxes, and raptors.

Also they are hunted by humans for sport and food.

It is also known as the mallard or the wild duck.

It is widely distributed across the world, except for Antarctica.

It can be found in various habitats, such as lakes, ponds, rivers, marshes, swamps, and coastal areas.

The Cryakva has a medium-sized body, with a length of about 50-65 cm and a wingspan of 81-98 cm.

It weighs between 0.7 and 1.6 kg.

It has a distinctive sexual dimorphism, meaning that the males and females have different plumage.

The female, or hen, has a mottled brown and buff plumage, with a blue patch on the wing called a speculum.

Both sexes have a yellow bill and orange legs.

The Cryakva is an omnivorous bird, meaning that it eats both plant and animal matter.

It feeds on seeds, grains, aquatic plants, insects, worms, snails, crustaceans, fish, and frogs.

It uses its bill to filter the water and extract the food.

It can also dive and dabble to find food underwater.

The Cryakva is a social and vocal bird, that often forms large flocks, especially in winter.

It communicates with various sounds, such as quacks, whistles, grunts, and squeaks.

It is also a migratory bird, that travels long distances to find warmer and ice-free areas.

It usually migrates at night, in V-shaped formations.

The Cryakva breeds in spring and summer, depending on the region.

It forms monogamous pairs, that stay together for one breeding season.

It builds its nest on the ground, near water, or sometimes in a tree hole or a nest box.

It uses dry grass, twigs, and feathers to make the nest.

The female lays 5-12 eggs, that are yellowish-gray in color.

She incubates the eggs for 26-28 days, while the male guards the territory.

The eggs hatch synchronously, and the chicks, or ducklings, are covered with yellow and brown down.

They are precocial, meaning that they can walk, swim, and feed themselves soon after hatching.

The female leads them to the water and protects them from predators.

The ducklings fledge, or grow their flight feathers, after 50-56 days.

The male usually leaves the female and the ducklings before they fledge, and joins a group of other males.
