Nesting

Common pheasants nest solely on the ground in scrapes, lined with some grass and leaves, frequently under dense cover or a hedge. Occasionally they will nest in a haystack, or old nest left by other bird. They roost in sheltered trees at night. The males are polygynous as is typical for many Phasianidae, and are often accompanied by a harem of several females. Common pheasants produce a clutch of around 8–15 eggs, sometimes as many as 18, but usually 10 to 12; they are pale olive in colour, and laid over a 2–3 week period in April to June. The incubation period is about 22–27 days. The chicks stay near the hen for several weeks, yet leave the nest when only a few hours old. After hatching they grow quickly, flying after 12–14 days, resembling adults by only 15 weeks of age.

They eat a wide variety of animal and vegetable type-food, like fruit, seeds, grain, mast, berries and leaves as well as a wide range of invertebrates, such as leatherjackets, ant eggs, wireworms, caterpillars, grasshoppers and other insects; with small vertebrates like lizards, field voles, small mammals and small birds occasionally taken.
