The Great Plains are a semi-arid place. Water is scarce. So, folks here have for hundreds of years come up with their own methods of predicting the weather. In is poem "How to Foretell a Change in the Weather," Ted Kooser records some of the methods he's heard. They involve the behaviors of cattle, sheep, dogs, cats, pigs, chickens, ducks, geese, pigeons, peacocks, guinea fowl, sparrows and even frogs (among others).
