The ancient Germanic people used the eagle, crow, and raven to foretell the future of specific issues and also to predict the weather. Should, for instance, you hear crows cawing in the morning, there is rain or snow on the way. If you hear the cooing of doves, then the day will turn out beautifully. I have used birds as a weather indicators for the past two years. I have run several experiments and kept notes to determine their accuracy. They are not often wrong. You also can control the weather by either cawing like a crow into the wind to bring rain, or coo like a dove to bring better weather.
When working with birds, it is best to form a relationship with those that are indigenous to your area. It is necessary for you to do some vision questing or meditation for several mornings and evenings, a few minutes at a time to connect with the birds around you. Setting up a bird feeder and bath is a delighful way to meet your birds and assist in protecting and caring for them. Since they are giving you answers to your questions, you should give them something in return.
Generally, the following birds predict fortunate outcomes: blackbirds, doves, ducks, hummingbirds, orioles, quail, pheasant, ravens, robins, sparrows, and wrens. Owls depict wisdom; the cry of the loon represents sadness. Numbers play an important role in dealing with birds. Once can count their actual number or the number of their calls. Even numbers are considered favorable, and odd are thought to be unfavorable. When listening, one or two calls are a positive omen; four or more are negative. If there are a multitude of cries, the answer is not yet determined.
