Warbler Guy: Which wood-warblers benefit from people changing their coffee drinking patterns by buying beans that are “shade grown”....?
Which wood-warbler species' utilize non-breeding season habitat in the tropics that includes "shade grown" coffee farms? In theory, is it correct that
changing coffee drinking patterns favoring "shade grown" coffee could benefit songbirds such as wood-warblers?
The brief answer, Jeremiah (in Rockford, IL)
is to note that several wood-warbler species likely
benefit from changed coffee farming methods that
favor “shade-grown” coffee, including Canada, Wilson's, Black-throated Green, and Cerulean Warbler. Cerulean populations, in specific, have dropped precipitously, perhaps in part due to habitat destruction of their "wintering" grounds (per Breeding Bird Survey trends and results suggested by other monitoring efforts).
