Take part in the RSPB's Big Garden Birdwatch - the world's biggest bird survey.

The survey is simple and fun, and can be done alone, or with family and friends.

Just watch and count the birds in your garden or local park for an hour on either Saturday 29 or Sunday 30 January 2005. Then tell us what you saw.

Results help us to keep track of bird populations right across the UK. In fact, this survey was one of the first to notice the decline in song thrushes since the late 70s.

So, if you have an hour to spare over the weekend of 29-30 January, please join us and make Big Garden Birdwatch 2005 the biggest and best yet!
