The Grey Partridge is a rotund bird, 28-32 cm long, brown-backed, with grey flanks and chest. The belly is white, usually marked with a large chestnut-brown horse-shoe mark in males, and also in many females. The only major and constant difference between the sexes is the so-called cross of Lorraine on the tertiary coverts of females - these being marked with two transverse bars, as opposed to the one in males. These are present after around 16 weeks of age when the birds have moulted into adult plumage. Young Grey Partridges are mostly yellow-brown and lack the distinctive face and underpart markings.


Habitat and Distribution

This partridge breeds on farmland across most of Europe into western Asia, and has been introduced widely into North America. They are quite common in some areas of southern Canada and the northern United States. They are also a non-migratory terrestrial species, and form flocks outside the breeding season.


Feeding

They are a seed-eating species, but the young in particular take insects as an essential protein supply.


Breeding

Hens lay up to twenty eggs in a ground nest. The nest is usually in the margin of a cereal field, most commonly Winter wheat.


Calls and Songs

The song is a harsh kieerr-ik, and when disturbed, like most of the gamebirds, it flies a short distance on rounded wings, often calling rick rick rick as it rises.
