Big Garden Birdwatch
More than half a million people are expected to take part in the RSPB Big Garden Birdwatch by watching for birds for an hour over the weekend.
The biggest mass participation environmental survey in the world has been providing data on the state of the UK's bird population since 1979
In the last decade the survey has shown a sharp decline in garden birds. Today the song thrush is seldom seen while even the most common birds like sparrows and starlings have dropped in numbers.
However because of the cold weather this winter, the charity are expecting more species including bramblings, siskins, redpolls and yellowhammers that would usually only be seen in the countryside to head to built-up areas in search of food. The cold winter in northern Europe also means birds rarely seen in this country are appearing in gardens looking for food further south.
