Ospreys are one of our best known and best loved birds and the name Roy Dennis is not only synonymous with the successful return of the osprey to Scotland, but is also renowned for his international work with a variety of species. The book follows the bird's fortunes in Scotland, seeing its numbers rise from that single pair in the 1950s to close to 200 pairs today. Roy's writings, at a time when no one knew whether or not his lifetime's work would succeed, add a sense of history to this personal tale.
