Oliver doesn't only snap birds; his camera shutter also clicks closed for the play of light across rippling water, the mist rising off a wood in early spring and the rolling Somerset hills where he was raised. But birds are a favourite subject of his, and his camera never fails to do them justice. Oliver's sensitivity to lighting, colour contrast and mood imbues each picture with a unique atmosphere, resulting in precise shots of professional quality. The birds' glossy eyes, their beaks, the intricate patterns on their feathers and the texture of their down have all been captured with a patience and skill that is admired by dedicated fans from all across the world.
