Preparations underway for 'Big Garden Watch'

The RSPB are gearing up for the thirty-fifth annual 'Big Garden Watch' at the end of this month.

The event sees members of the public up and down the country take part in one one of the world's biggest wildlife surveys.

Since it began in 1979, over half a million people have given up an hour of their time over a specified weekend to count and identify the birds they see in their gardens in order to build up a picture of the health of the populations of some of Britain's most popular garden Bird species.
