Bird discussions and identification

Heard a very loud continuous bird song which led to sighting a small yellow bird with bright orange beak sitting on my TV arial. Hunted down my camera and here this little bird is, about the size of a sparrow. Not a sign of it in my guide to European birds and cannot ID it on the internet. Anyone have an idea what this bird is please? Yellow with orange beak and loud continuous song. Fast flyer.
