These species, a group of about 150 ground-dwelling gamebird, are found on every continent apart from Antarctica. They live in a wide variety of habitats from tropical forests, high-altitude alpine zones, temperate forests, open country, to desert environment. Although widespread, little is known of the species occurring outside Europe and North America, but several species are considered at grave risk of extinction. Since publication of the first action plan in 1995 a large increase in the amount and quality of conservation work has taken place. This document provides an update on the current situation, identifies the most threatened species with this group, prioritizes conservation action needed, and outlines project briefs for the most urgent cases.

This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel's, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly popular with naturalists, birders, and other outdoor enthusiasts.
