Résumé
As her training at a wildlife centre draws to a close, Joanna finds out if she's passed the test to become a fully-fledged volunteer. But first, she needs to bring the swallows she has been looking after back to the centre for a flight test. She gets to release the tawny owls with all the team watching on. And she does her very first completely unsupervised release - a fox cub back to his family.
