I'm trying to do a tattoo of every British bird

Charlie Sullivan is a tattoo artist from Coventry and he's set himself a rather unusual challenge: to tattoo images of every single species of bird native to Britain. Charlie Sullivan has already completed over 90 bird tattoos; all the birds are chosen by customers using a gumball machine, and he's raising money for the RSPB along the way. Charlie told BBC CWR's Vic Minett when his love of birds first began.
