Can Sun and Moon Charts Predict Wildlife Activity?

Systems claiming to predict fish and wildlife activity based on solar and lunar gravitational forces are popular among sportsmen. If valid, these could have implications for wildlife management. Two such systems, the Solunar TablesĀ® and Fish and Game Forecastet, were evaluated using data from free-ranging and captive birds and mammals. Neither system accurately or consistently predicted activity, although some data sets revealed suggestive relationships.
