The results for this year's Big Garden Birdwatch are in - and numbers for small species were dramatically down against the mild winter of 2009, the RSPB survey found. Long-tailed tits were down 27% on 2009, coal tits down 20% and goldcrests down 75%. The long-tailed tit, which is just 14cm long, is particularly vulnerable to freezing weather, but has thrived due to a succession of mild winters and was one of last year's big success stories.
The snowy winter also led to a huge rise in sightings of countryside birds such as thrushes and finches in the UK's gardens. The number of fieldfares was up 73% on last year, redwings up 185% and song thrushes up 51%, though their numbers are still relatively low compared to garden stalwarts such as blue tits and chaffinches.
The full data is below. You can also compare it against 2009's findings, see how we visualised the 2009 data and see how developer Matthew Thorne turned the statistics into a webtool called Beaky birdsearch.
