Extremely rare bird caught on camera in Aylesbury village
Richard Stevenson took the snap of the rare bird near his home in Witchurch.
The blackcap is a distinctive greyish warbler, the male has a black cap, and the female a chestnut one.
Its delightful fluting song has earned it the name 'northern nightingale'.
Although primarily a summer visitor birds from Germany and north-east Europe are increasingly spending the winter in the UK.
They are known to eat insects and berries.
