A new study tries to determine what economic value residents in two comparable cities place on having birds in their backyards and parks. Researchers compared two types of common birds -- finches and corvids -- in both cities, asking residents how much they would pay to conserve the species and what they spend, if anything, on bird food. In Seattle, that value of enjoying common birds is about $120 million annually and in Berlin, $70 million.
