i heard a story many years ago that unpon a death that a crow will show up at the location to carry the soul to its final resting place and if there is a second or third crow close that sole is important and is protected by those other crows being guardians.
it came to my attention as a few days ago an old man opposit my house passed away he had lung cancer and had been fighting it for four years but in the end it got the better of him (he was in his late 80's) and there was a crow that was there from the day he died to the day after the wake at his house and ive not seen any crows since.
