True blue?

If you've been reading the mag, you'll probably have read about the "blue sparrow mystery". A guy in Sydney, Australia, spotted what he described as an unusual-looking bird in his garden. It looked just like a sparrow, he said, but it was blue. Surely this can't be right...can it? Experts are baffled. Could it be a new type of bird? Or is there a perfectly logical explanation? Perhaps it's the lighting, some say, or maybe it's been eating some sort of blue food that has affected its colouring. Click here to see the photo yourself and tell us what you think.
