What is the meaning of a thrush flying into your window?

Not all naturally occurring phenomenon can or should be interpreted as omens.

In the case of a bird appearing to try to get in via a window, there are several reasons why this may be happening.

- in some light conditions a window's surface can become reflective (like a mirror) and the bird may be trying to get into the reflection of the garden or landscape behind it.

- it may see its own reflection as a rival for territory and be trying to chase itself away.

- the bird may have become disoriented and be trying to escape.

The only time when this behavior should be interpreted as an omen is if the kind of bird (raven, robin, hummingbird, etc) is significant to you personally and if the window is to your own personal space. In which case the interpretation is individual and not a "general" omen.
