If the sparrow makes a lot of noise, rain will follow. When parrots whistle, expect rain. Fish bite best before a rain. When fish break water and bite eagerly, expect rain. When porpoises sport and play, there will be a storm.
Trout jump high when a rain is nigh.
If anthills are high in July, winter will be snowy. If the first week in August is unusually warm, the coming winter will be snowy and long. For every fog in August, there will be a snowfall in winter. If a cold August follows a hot July, it foretells a winter hard and dry. Squirrels gathering nuts in a flurry will cause snow to gather in a hurry.
