The best-known avian omen is the albatross in the poem, "The Rhime of the Ancient Mariner" by Samuel Taylor Coleridge", The albatross is an enormous ocean-flying bird that can fly for miles and miles without landing and is considered a favorable omen among seafarers. In the poem, the ancient mariner kills the albatross that has been following the ship and it is beset with woe.... Clarification: The above mentioned belief is for a specific bird (the albatross) and it's being seen as a good omen when it "follows" ships. There is, to my knowledge, no omen connected with an unspecified wild bird actually landing on you. The good luck is in that you were lucky enough to be out in nature, and either still enough or patient enough for one of nature's creatures to land on you, otherwise, a bird landing on you is not an omen of any kind. SINCE wild birds do not generally land on humans, it is an attempt to draw your attention to the bird, which is trying to get you to think about it. Have seen this when spiritual people pass by. the "helper" birds will fly towards them. Often you will have an ancestral connection to this bird, or there is a spiritual message that is trying to reach you.
