Charlie Sullivan has so far ticked off 86 species and raised £2,000 for the RSPB.

Charlie Sullivan has been a tattoo artist for 10 years and birds have always been the biggest inspiration for his artwork.

The 31-year-old, who works at the Golden Goose tattoo studio in Birmingham, said he had been drawing since he was a child and had always been obsessed with bird watching.

This love has led him to embark on a challenge to complete tattoos featuring every single bird native to Britain.
