I once heard it's good luck when one of these fellows come for a visit, today I was feeling a little blue, I went to my special place, and in the lonliness of it all, here the blue heron comes to say everythings going to be ok.
Heron: is associated with morning, and is the first bird to salute the dawn. A heron also tied in with regeneration of life. A heron provides for its young like a stork. It is associated with longevity, silent memory, overcoming danger, indiscretion, dual nature: because of it amphibious nature, and melancholy. The heron is sacred to the Muses and is related to priesthood. Herons are seen as a favorable of men. When heron's leave the marsh and fly above the clouds they announce the coming of a storm.
...signifying the world of life and light, as opposed to that of death and darkness. For the same reason the snow-white heron was much esteemed,... and the blue heron for luck in life.
