Good spring for Cornwall's Greenfinches?

No.:  2014-33
June 2014

Despite the fact that they are declining across the country, Cornwall’s Greenfinches seem to have had a very good spring. In order to work out why, the British Trust for Ornithology (BTO) Garden BirdWatch needs the public’s help.

Cornish Greenfinches have experienced similar
results to those in the rest of the country

Cornish Greenfinches have experienced similar results to those in the rest of the country, with the population dramatically declining since 2005 due to a disease known as trichomonosis. The decline has been extremely noticeable in gardens across the country, and BTO Garden BirdWatch average weekly counts for the nation have dropped from between four and five individuals a week, before the disease struck, to fewer than two.

However Greenfinches in Cornish gardens seem to have had a boost this spring with the highest numbers of Garden BirdWatch gardens reporting them since 2010. Whilst the peak percentage of Garden BirdWatch gardens reporting Greenfinches this spring was around 60%, in Cornwall it was 70%. Will they continue to do much better in the west country? We don’t know – and that’s why your help is needed!

BTO Garden BirdWatch is the world’s largest year-round survey of garden birds, having run every week since 1995. Anyone who enjoys watching the highs and lows of their garden birds is welcome to get involved in this simple survey, and your sightings can contribute to our knowledge of how birds like Greenfinches are faring. 

Clare Simm, of the BTO Garden BirdWatch team commented: "Watching birds in your garden can be like watching your own mini soap-opera. The squabbles, the friendships, the family bonding – it’s incredibly interesting and fun to discover."

She added: "If you spend a few minutes each week watching what birds get up to in your garden, then you are already doing enough to take part in the BTO Garden BirdWatch. Get in touch with us for a free magazine and information pack on how to take part."
