This is a book about a game ranger (George Adamson) who had to shoot a lioness, and then realised she had cubs. He raise raised one cub-Elsa by hand, with Joy his wife and reintroduced it to the wild.
This contains the first book in the trilogy: Born free (the combined book is out of print)
Joy Adamson was a profilic author and I have many of her books. Currently most of them are out of print, but will add more if I find them online. It is worth searching Amazon for second hand versions of her other books, in particular: the Queen of Shaba and the Spotted Sphinx
In the shadow of man
This is the tale of Jane Goodall at the beginning of her study of the Chimpanzees in Gombe stream. Also sent by Louis Leakey she discovered tool use amongst chimpanzees.
Life on Air
David Attenborough stands above all other wildlife documentary makers worldwide. Having been writing and or narrating some of the biggest for 50 years.
With fascinating encounters with all sorts of animals his memoirs are going to thrill
Adventures of a young naturalist
The stories of David Attenboroughs early travels, back in 1954 when he started working for the BBC. Stories of trekking to catch the Komodo dragons and other creatures for the London Zoo. While this would not be acceptable now, discoveries made then often inform what we do now- in terms of conserving the animals for the future.
