Figure 13. The "Gallinaceous Guzzler." This is a device to supply water to quail 

 and other small game in arid areas in California. This self filling watering unit is inex- 

 pensive to install and requires little or no maintenance. The "Guzzler" is filled by winter 

 rainfall and stores water underground for summer use by quail. The birds get the water 

 by descending a ramp. 



Figure 14. Cutaway of "Gallinaceous Guzzler." This shows the details of con- 

 struction of the "Gallineaceous Guzzler." All construction is of concrete. The underground 

 tank holds about 750 gallons of water. Concrete roof and bafHe slabs retard summer 

 evaporation. The rain collecting apron is made of concrete covered with asphalt emul- 

 sion ; the size of the apron is calculated on the basis of the minimum recorded rainfall 

 for the area in which the "Guzzler" is installed.
