Do birds fly low expect rain and a blow true or fales?

The saying "Birds fly low, expect rain and a blow" suggests that birds may fly at lower altitudes when bad weather is approaching. This behavior is often attributed to changes in atmospheric pressure and humidity that can precede a storm. While it's not a strict rule, many birds do exhibit alterations in flight patterns in response to weather changes. Thus, the statement can be considered generally true, though not universally applicable to all bird species.
