Crows can actually predict the weather
There is speculation that birds – especially crows – can predict the weather better than a meteorologist. To be more specific, it is said that if a crow flies alone, it means that the weather will be bad, but if they fly in pairs the day will be serene.
But according to some scientists, birds do not fly when a storm is in its way. They will stay on a power line before the rain hits and they will feed in the morning so that there is no need to fly when it is bad weather. So, birds have to migrate because of these climate and atmospheric changes as well.
