The RSPB's Big Garden Birdwatch this weekend is the world's biggest wildlife citizen science project.

Half a million people take part - either in their gardens if they are lucky enough to have one, from their windows or in nearby public spaces.

The charity says the survey gives vital insights into the UK's bird population.

Many of our most familiar species have seen steep declines over the survey's 45-year history, including sparrows, starlings and greenfinches.

The RSPB is urging as many people as possible to get involved this weekend. Here's how.

Here are some of our favourites from you so far.
