To my knowledge there is no symbolic meaning of the action.
It was an old practice to hang a game bird by its neck to "ripen" the meat, when the bird fell, the meat was ready to be cooked.
Birds die like any other animal. There is no need to look for symbolic meaning in ordinary events.
Means nothing but a dead bird. I suggest that something ate the head or it fell off.
you will regret that (your dead)
it drowned
It's not alive anymore.
well if a really creepy lady live near your house then yes it means she is a witch if not then its just a dead bird
you have a catBird could have died of the West Nile virus
It means you need to toss it in the garbage.
It means an owl has died and that is where it has landed. Either because it was roosting in a tree nearby or it was flying overhead and died above your property by chance. There is nothing creepy or supernatural or symbolic going on, its just a dead bird. It could have landed anywhere, but it happened to land in your "abundance corner".
Either a bird has died or been killed on the driveway, or it sdead body has been moved there (for example by wind or carried by another bird).
If a bird breathed when it was dead, then the bird wouldn't be dead. So, no.
It means bad luck is going to come your way
