Migration is one of the many adaptations used by birds and other animals to cope with the cold temperatures and scarcity of food that winter can bring. As scientists and naturalists we are interested not only in where birds go in the winter, but in how we know where birds go in search of more hospitable conditions. Traditionally, scientists captured, tagged and released individual birds and hoped that someone, somewhere, would find this bird and report its whereabouts.

The people who manage the Berkeley Pit want to use lasers and cannons to try to save lives of migratory birds. Thousands of geese were killed last fall in the poisonous water of Butteā€™s Berkeley Pit. It was an environmental catastrophe that Mark Thompson hopes is never repeated.
