Quote from : Great Possessions : An Amish Farmer's Journal Book

The perfect weather that had allowed us to get the oats and corn in ahead of time probably also contributed to the dearth of migrating warblers. With no storms to force the birds down, they overflew this area on their northward journey. At least I hope that is the reason. I fear, though, that the cutting down of the tropical rain forests (the winter home for many warblers) to create ranches that will provide cheap beef for fast-food restaurants in the United States may also be partly responsible for the dearth.
