A Study of the Food Habits of California Game Birds and Mammals and Species Affecting Their Welfare. As an integral part of wildlife management studies now in progress in California, it is necessary to obtain information as to the food preferences of game and predatory species. C. M. Ferrel is leader of this project. Project 30-R. A Study of Production, Migration and Wintering Areas of Water- fowl in California. An evaluation is being made of the production and wintering grounds of the principal waterfowl areas of the State, which includes Suisun Marsh and the Sacramento-San Joaquin Delta, the Inyo-Mono and Owens Valley area, and the northeastern section of California. These studies include large scale trapping and band- ing operations of resident and migratory waterfowl. Also, an investigation is being conducted on the effects of reclamation projects and land uses on waterfowl popula- tions. A. W. Miller is the leader of this Trapping and banding waterfowl not only provides information on migration, but also shows rates of harvest for various species. Project 31-R. A Study of the Effects of Brush Removal on Game Ranges in Cali- fornia, will determine sound methods for management of brush areas for wildlife habitat improvement. The project is under service agreement with the University of California, with Dr. H. A. Biswell as leader. Project 33-R. An Evaluation of Quail Development and Management Practices in California. Studies are being conducted to determine the effects of cover planting and water development on quail populations. Types of construction and the value of arti- ficial roosts are being tested. Also, the effects of cover removal, grazing, cultivation, controlled burning, rodent control, predator control, and hunting pressure on quail po
