How Birding is Like Quantum Physics

This gem was posted here by Jerry Blin:

The act of identifying a bird often changes its identify.

The act of locating a bird changes its position – in fact, maybe it was never there after all.

It may no longer be a bird – it may now be something else. Then, again, maybe it never was a bird.

The Red-footed Falcon of yesterday can be something entirely different today – in fact, it can become something entirely different yesterday, too.

And some people think birding is easy!
