It has been a triumph for small birds across the UK as one of the largest mass surveys reports a rise in sightings of Goldcrests, Long-tailed tits and Coal tits compared with last year.

The survey by the The Royal Society for the Protection of Birds, included over 600,000 people reporting bird sightings across the UK - a record breaking number for the Big Garden Birdwatch. Camilla Turner writes today:


"The findings indicate that sightings of goldcrests, the UK's smallest birds, doubled. Long-tailed tits have increased by a third, and coal tits by a quarter. Thousands of people were also lucky enough to see waxwings. These birds flock to the UK from Scandinavia in some years, and this winter there was an influx with more than 7,000 spotted in almost 1,000 gardens, making it the most popular winter for waxwings in more than 30 years."

The results came as a suprise after a harsh winter in 2009 caused a significant drop in numbers for the small birds. Over 10.2 million birds were counted as part of the survey this year, including over 70 species. The results show that Starling sightings have increased by a quarter since 2010 and the house sparrow remains the most highly spotted bird in UK gardens.

The full data can be found below. Comparisons with the 2010 results are in the spreadsheet. What can you do with this data?
