These are the birds most regularly spotted in London's gardens. We've shown them in relative proportion. So, for example, blackbirds (centre-right) are roughly four times as common as jays (bottom-right). Most common of all are the woodpigeons (trooping across the top of the image), closely followed by the plucky house sparrow, whose numbers are nevertheless in decline.
The image is based on the most recent Big Garden Birdwatch, an annual survey of the nation's avian populations. The survey data is for the whole of Greater London, not just the centre, and is based on thousands of observations by Londoners.
Here they are in order of abundance (roughly top to bottom in the image).
