Extract

There have been few quantitative studies on the role of woodpeckers in control of insect pests. Hutchison (1951) and Wygant (1958) pointed out the importance of these predators in reducing outbreaks of the Engelmann spruce beetle and Knight (1958) established a means of assessing the value of woodpeckers by correlating their activity with beetle survival but made no attempt to measure the numbers of woodpeckers in an area.
