Like partridges they are basically monogamous, though the male has far less interest in the young. If they female population in an area is greater than the male, some males will have two females in their territory. Common quail normally fly north from Africa to Europe to breed, though some may stay in north Africa for their first brood and then fly north for a second brood. Quails eat a higher proportion of insects and other invertebrates, are smaller then partridges and have been introduced into North America and New Zealand. There are over 100 species of quails and partridges.
Female pheasants are all much duller than their male partners.
Pheasants, like all the game birds have calls which are not particularly musical to the human ear and in many cases are quite harsh. Pheasants are essentially polygamous with the male calling and displaying to attract females and playing no part in nest building, incubation or protecting the young. Mated females make a nest of a small depression scraped in the soil and lined with dead vegetation into which she lays about 7-15 eggs which take about 4 weeks to hatch. The young are precocious but stay with their mother for some time after hatching - at least until they can fly. Like the rest of the Galliformes, Pheasants are ground-feeding omnivorous birds, feeding mostly on insects, seeds and fruit.
