The number of robins visiting UK gardens has hit a 20-year high, according to the latest Big Garden Birdwatch survey. Organised by the RSPB, the citizen science project recorded average robin numbers not seen since 1986, placing the bird seventh in the rankings of most commonly seen species.
The survey, which involved more than 497,000 participants, also reported a 'waxwing winter', with large numbers of these striking migrant birds arriving from Scandinavia. Waxwings, known for their dusky pink colouring and punk-like crest, were spotted in about 11 times more gardens than in previous years, reaching as far west as Wales and Northern Ireland.
RSPB conservation scientist Daniel Hayhow said: 'Flocks of these striking looking birds arrived in the UK along the North Sea coast and will have moved across the country in search of food, favouring gardens where they can feast on berries. With it only happening once every seven to eight years, it will have been a treat for the lucky people who managed to catch a glimpse of one.'
Other migrant birds, including redwing, fieldfare and brambling, also saw increased visits as sub-zero temperatures on the continent pushed them towards the UK's milder conditions. Blackbirds had a good year, rising to third in the rankings and becoming the most widespread garden bird, seen in 93% of gardens.
However, sightings of blue tits, great tits and coal tits declined, likely due to prolonged wet weather in the 2016 breeding season reducing survival rates. Sparrows and starlings remained in first and second place, with slight upturns in numbers compared to last year, though both species have suffered long-term declines.
The RSPB highlighted the positive impact of wildlife-friendly gardens, with 16 of the top 20 species showing increased sightings between 2016 and 2017. Wildlife adviser Claire Thomas said: 'Our gardens can become an invaluable resource for birds – throughout the year birds need food, water and a safe place to shelter. If we all provide these things in our outdoor spaces it will be a huge help to our garden birds, perhaps even playing a role in reversing some declines.'
