Disappearance of song birds
Nature
Song birds are negatively affected by urbanization and intensive management. The single greatest threat to the songbird's survival is the surge in aggressive sun-grown coffee production, now the most popular method of growing coffee in Latin America. Sun-grown coffee requires clearing the forest and removing the natural shade used by the songbirds and other creatures. It is a high input process useing chemical fertilizers and pesticides to enhance production. Migratory songbirds are dying by the thousands as a result of these practices. Shade-grown/organic coffee, on the other hand, used the forest's natural shade to produce coffee in the traditional manner from the natural, shade- loving coffee shrub. Many of the overstory trees are nitrogen fixers, enriching the soil which reduces the need for chemical fertilizers. Migratory birds thrive in this environment. By 1990, over half of the traditional coffee farms in Latin America had been converted to the sun-grown method of coffee production, permanently destroying songbird habitat and thousands of hectares of rainforest. Fewer than ten percent of the birds that thrive in shade- grown coffee farms can survive in sun-grown plantation environments.
Background
Migrating songbirds need large tracts of undisturbed forest but have been forced to live in small, pocket-sized woodlands. As a result, their eggs are frequently eaten by forest-edge birds such as grackles, crows, and cowbirds. In addition, their eggs are eaten by cats and dogs from nearby urban areas, and by opossums, skunks, raccoons, and foxes, which avoid deep forests and thrive in suburban areas. Migrating songbirds, searching for undisturbed forests, expend excess time and effort. Further, dislocations make it difficult for them to fill all their needs, raise their young, and prepare for their winter migration.
Claim
If only 10% of all American coffee drinkers demanded coffeegrown by traditional methods, approximately 135,000 hectares of coffee producing land in Northern Latin America could be converted back to the shade-grown/organic method. This conversion would give the displaced songbirds new habitat in which to live and flourish.
