Nothing it probably couldn't see and landed on you because you were so still. (A few years ago a bird pooped on my head, then some years later another bird pooped on my head). So I strongly advise you to make sure one doesn't land on you and make sure your not standing underneath a bird when they need a moment, and DON'T STAND UNDER A TREE either.
Head of a woman and body of a bird? I believe you happen to mean a hagraven or a harpy.
Means nothing but a dead bird. I suggest that something ate the head or it fell off.
Could be that the one bobbing its head is a baby and the bird is begging for food from the other bird.
Birds like having a lookout point. If a bird lands on your head, it may think you make the perfect perch to see the going ons around them. If you mean a 'pet' bird, it could also just be the bird's desire to be close to you, as birds do form attachments to their owners.
Nothing. You are being used as a bird roost.
The bird's nest on a grave could be representative of the story of Kevin of Glendalough who it is said, during Lent, fed a blackbird which landed in his hands. The bird eventually gave birth to hatchlings at the end of Lent.
a dead pigeon with its head chopped off was left on my patio
If by "they" you mean Apollo 11, they landed on Mare Tranquillitatis.
It means that the bird hit your window so hard that it died.
Bird in French is l'ouisseau. (phonetically: la'wazo)
The mean bird is Nigel He is a cockatoo from Austalia
I don't think so. At least, he didn't use to be, I mean, he bit a bat! And he ripped off a bird's head with his mouth!
