Helpless raccoon foundlings and tiger babies, young injured otters, manatees in need of care and orphaned bear babies: The "Wildlife Nannies" inform us about animal baby rescue operations in North America and Europe, as well as of the people involved, who passionately intervene to save them. They do more than just carry out their duties as doctors and helpers; they are often on hand for their fosterlings for 24 hours a day and are needed and accepted by the animals as surrogate mothers - or nannies. The "Wildlife Nannies" also tell of the tightrope walk, not to become too attached to wild animal babies, so as to be able to return them to their natural surroundings once fit. But sometimes, it is not possible to release the cute foundlings, who then have to be prepared for life together with their guardians. For the nannies, the work with the animal offspring is more often than not a life task, which they conduct with dedication and passion. The upbringing of the animal babies' calls for much more than just cuddling and petting them; a professional, species-appropriate attitude and care is of the utmost priority. The exciting tales of the "Wildlife Nannies" take us on a journey to the care and foundling stations, to private animal rescuers with a fostering license, as well as to wildlife parks and zoos that strive to ensure the conservation of the animals.
