For one thing, Woods now believes that deer react to imminent changes in weather patterns that they detect with their heightened senses. These changes won't occur for 24 to 48 hours, but when the conditions are right, deer are driven to feed. "We've tried all the simple correlations--barometric pressure, the moon, weather conditions--and none of them have shown any degree of accuracy," says Woods. "We just don't have the right kinds of data yet that will show exactly what combination of factors deer are sensing, but I'm sure the answer is out there. This is an exciting time to be involved in deer research."
