|Bugs come to light|
In my own barn the female has built a nest between two lights that serve our driveway. She looks like a pilot at the helm of a big machine. At first she flew out each time we crossed into our barn. Seemed like a silly place to nest if you are human phobic. Then one evening as I went to feed the chickens I realized that the lights were attracting insects up into her nest. Food delivered bedside!
For a historical review and fun facts about the symbolism of barn swallows go to symbolism of barn swallows-- here-- "Swallows are often associated with stars and therefore the souls of the dead. Chapter 86 of the Egyptian Book of the Dead specifically instructs the deceased on how to transform into a swallow."
