Thank you to everyone who contributed to our 2012 house sparrow survey, updating one completed in 2002.

We asked you to tell us where sparrows live in London so we could compare the findings of the two surveys, revealing change over the ten year gap. There's been no dramatic change, in fact the 2012 results reinforce…

With this in mind, what better place to meet and share…
