FRAZIER Game Management Branch, California Department of Fisin and Game INTRODUCTION The major effort toward habitat improvement for upland game in California has consisted of installation of a Avatering device known as a "gallinaeeons guzzler" in the arid areas of the State where absence or paucity of water was determined to be the limiting factor in the production of game birds.
