My first thought is how do you know it was placed there? Often when small birds impact with a window they die of the concussion and appear as if they have been placed where they drop.
Not all naturally occurring phenomenon have supernatural explanations. Sometimes a tiny dead bird is just that.
Not all naturally occurring phenomenon can or should be considered an omen or symbol. In this case it is more likely than not the bird died of natural causes (be they be accident, natural predator or illness) and you simply found it. Unless that species of bird is of personal significance to you I would not look further into the meaning.
Not all naturally occurring phenomenon can or should be interpreted as an omen or sign. Most often finding a dead bird in or around a house or building can be attributed to either the bird flying into a window, or a "gift" from the household cat.
Its significance is that you will have lots of luck when times are bad, but when times are good you will have bad luck.
If that somebody is a cat, it means that the cat thinks you are hungry and you need a bird to eat.
Someone from Hawaii wants you dead.

A dead bird is said to be an omen. This is believed by many to be a sign of bad luck.
It flew in when I opened up the door.
You left a door or window open.
Nothing. You have a dead bird.
I would guess it depends on the bird, like a crow or an owl. Granted the poor thing just stuck in your garage and killed itself trying to get out. If you have a cat or a dog then think of it as a gift for the family!
Voodoo is real to some people especially to those who practice it. Some practice it as a religion. If there is a dead black bird at your door, usually it is a threat, or warning. It can sometimes signify death of either you or one close to you.
Means nothing but a dead bird. I suggest that something ate the head or it fell off.
