In "The Long Winter" by Laura Ingalls Wilder Pa forsees a very bad winter when the water birds don't stop over in the lake on the way south and the rodents build dens with extra thick walls. The winter turns out to be very bad indeed (they nearly freeze and starve).
Do wild animals predict weather accurately like this? For what time periods? What behaviors predict the weather? Are there any theories about how they do it if so? What are they predicting now?
