The Effect Of Orientation And Light Intensity On Utilization Of Artificial Wood Duck Nest Boxes

Artificial wood duck nest boxes were surveyed during 1977 on the Bear Creek Waterfowl Management Area in west Tennessee. Box types used were wooden, metal vertical, and metal horizontal. Utilization, height, orientation and hatch success were recorded. Light intensity readings were taken on ten days. Utilization was 15% for wooden, 27 percent for metal vertical, and 0 percent for metal horizontal. Nest success in terms of percent hatch was 73.4 percent for wooden and 84.0 percent for metal vertical structures. The mean angles of utilized and unutilized boxes were not significantly different. There was no difference in light intensity between wood and metal boxes. Utilization was not dependent upon light intensity; rather visibility favored utilization.
