Coffee grown under a tree canopy is promoted as good habitat for birds, but recent University of Delaware research shows that some of these coffee farms may not be as friendly to our feathered friends as advertised. “A very common scenario on these farms is to have eucalyptus, pine, mango and citrus,” Tallamy said. “All of these are non-native trees that support few insects — critical food for birds — or not nearly enough insects to make a difference. If you have a substantial amount of land with non-native plants, we’re not helping the birds at all. Biodiversity-wise, it’s a real scourge.”
