Today's the day, folks, it's the RSPB's Big Garden Birdwatch.

All you have to do is spend an hour today or tomorrow watching the birds - whether in your garden, a local park or in the woods. Just record the numbers of the species that you see and send the results in to the RSPB.

The RSPB is hoping that around 500,000 people will be able to record the abindance of birdllife in their gardens, parks and the countryside.
