Birds fly! Basic Fact!
This gives them an incredible perspective on the world, a detachment from the everyday, a global overview.

They also come through very strongly as messengers if we choose to listen. The most significant of these is when a bird appears at the time of passing over of a loved one. They seem to appear in various forms and I do get commissioned to paint these messengers. Very special.
