Dr. Kerri Vierling of the University of Idaho Fish and Wildlife Department has been performing research centered upon woodpeckers for more than 14 years
-Habitat selection
-Breeding habits
-Other animals using woodpecker tree cavities
-Predatory information
A topic of concern for conservationists globally
Motivation
1. No data storage2. Unwieldy3. Poor battery life4. Weather dependant
Previous System
-Photos in low light conditions-Continuously powered (4 months)-High data storage capacity
-Triggered by animal presence-Internally mountable
-Functions during extreme weather
