BTO reveals England's going for goldfinch

...But song thrush numbers have halved

March 2012: Goldfinches are the star garden visitor for many people in Britain, according to the report on this year's BTO Garden BirdWatch.

The British Trust for Ornithology first carried out the survey 16 years ago, and it has been held every year since. The figures for 2011 show that nearly five times as many gardens are visited by goldfinch as 1995, but the number of song thrushes spotted in gardens has halved over the same period.

Numbers of the dazzling goldfinch in gardens have reached an all-time high. Far more householders saw this species in 2011 compared with 16 years ago. This meteoric rise has seen goldfinches rocket from number 20 in the garden bird ‘league table' to number ten.

Bullfinch is a garden regular in WalesEngland topped the podium for goldfinches in 2011, with 58 per cent of gardens visited during a typical week, compared with 53 per cent in Wales and 49 per cent in Scotland.

Meanwhile, Welsh gardens boasted the highest reporting rate for the handsome bullfinch, an increasingly common garden visitor. Scottish gardens were best for both starling and greenfinch - although numbers of these species in gardens across the UK last year were at their lowest in almost a decade.

Wren and song thrush waningAfter a succession of cold winters, numbers of the diminutive wren visiting gardens have dropped. Compared with the long-term Garden BirdWatch average, as calculated from 1995-2010, around one in three householders have now lost this beautiful songster. Another cherished voice that is ebbing away is that of the song thrush, with half as many gardens visited during a typical week last year compared with 1995.

Brambling boomThrough the year-round recording of BTO Garden BirdWatchers, fascinating seasonal patterns have emerged. These volunteers keep simple weekly records of the birds in their gardens. During late winter in 2011, brambling numbers soared, up by almost 250 per cent on the same period in 2009 and 2010.

Blackbird numbers down 40 per centSpring 2011 saw numbers of goldfinch and bullfinch in gardens rise well above the average of the previous two years, while numbers of siskins spotted in gardens during last summer were up by a quarter. 

Gardens were relatively quiet during autumn and early winter last year, with thrushes particularly notable by their absence - blackbird numbers, for example, were down by 41 per cent compared with the same period in 2009 and 2010.

BTO's Dr Tim Harrison said: ‘Improved foods and feeder designs, coupled with feeding pressures in the wider countryside, appear to be driving goldfinches and other farmland species - such as bullfinch, reed bunting and lesser redpoll - into gardens.

‘Every season and every region has its garden bird highlights. The size of the influx of brambling last winter, for instance, exceeded all previous Garden BirdWatch records. English gardens are the best place to see species such as blackcap and long-tailed tit, Welsh gardens for the blue tit and robin, and Scottish gardens for tree sparrow and coal tit.'

He concluded: ‘For every garden bird success story - such as goldfinch and bullfinch - there is, unfortunately, a species faring less well. Mistle thrush, for example, is really struggling. During 2011 the percentage of gardens visited by this imposing thrush was at its lowest point in the 16-year history of BTO Garden BirdWatch, and it is now largely absent from gardens in Greater London.'
