White Feather

I spotted this tiny feather on or back doorstep and according to Mr Google ;- 
Angel expert and author Diana Cooper, 75, says that finding a white feather is a sign that an angel is present. “Angels place feathers to give us hope and encouragement,” she says. 
“The angels are showing you that they are trying to help or guide you.
I hope this is true and not one of our little feathered friends has hit the window.
