Like coffee? Is it shade-grown? In winter, Scarlet Tanagers migrate to southern South America. But there has been some loss of important habitat there because forests are cleared for non-traditional full sun coffee plantations. Choosing shade-grown coffee can help these gorgeous birds. Once they return in the spring, in spite of their brilliant plumage, these colorful birds can be hard to find because they prefer the high treetops of the forest canopy. Photo: Penn State
