The phrase, “as the crow flies” means in a straight line. Generally used when discussing distances. Any distance 'as the crow flies' neglects barriers (man-made or natural, such as traffic, mountains, waterways, etc.) that might hinder your travel, it is the shortest route between two points."
Here’s my little crow I picked up at Sweet Annie’s! Only this little crow had to fly around the flooded roadways in order to get to my place!
Crows on the fence mean rain, while crows on the ground mean fine weather.
Whether there is any truth to that or not I don’t know, I do know when I see a crow, it is another one of those things that calls my name. :-)
