What does the black bird represent?

[Quan]

Hey gang,

The theme of a black bird (crow, raven, magpie, etc) has come up in my experience as of late and was wondering if anyone here knows of any non-specific symbolic meaning it may have, if that is possible?

Thanks all,

Whatever rings true for you is all that matters.. 
On a side note not sure if you are from or been to Australia, here there is actually a bird called a black bird- its black with orange beak. Name is so simple but it is a amazing song bird and before sun comes up and sun coming down then few other times every day in routine it will sing the most beauitful songs for over 30 minutes sometimes 1 hour or more. Each bird is different, usually you will find them at top of highest tree or point when they sing.   Its songs are one of most beauitful I have heard of any bird, really incredible.
