Three-quarters of the world's coffee farms destroy forest habitat to grow coffee in the sun and typically use harmful pesticides （杀虫剂） and chemicals that poison the environment． When forests disappear， migratory （迁徙的） songbirds disappear， too． In order to deal with severe population and habitat loss， Smithsonian scientists created the Bird Friendly certification．
Bird Friendly coffees are shade-grown， meaning the coffee is planted under trees， rather than on the land that has been cleared of all other plants． Coffee experts say shade-grown coffees taste better， because the beans ripen slower than coffee grown in the full sun， resulting in a richer， more complex flavor． Bird Friendly certified coffees grow under bio-diverse shade that provides habitat for migratory songbirds and other wildlife， stores carbon and fights climate change． Bird Friendly coffees are also certified organic， meaning they are grown without pesticides， which is better for people and for the planet．
Bird Friendly producers can also earn more for their crops． The wood and fruit trees on shade coffee farms provide farmers with additional income． Every cup of Bird Friendly coffee purchased rewards these farmers with a little more money for being good stewards of the environment and encourages them to continue conserving Bird Friendly habitat．
Buying Bird Friendly supports the Smithsonian Migratory Bird Center's conservation research aimed at understanding and protecting your feathered friends． You can purchase Bird Friendly certified coffees around the world and protect wildlife and habitat with every cup． Find a store or cafe near you， or better yet， have it shipped to your door when you order online．
