"If naturalists go to heaven , I hope that I will be furnished with a troop of kakapo to amuse me in the evening instead of television."

“The purpose of keeping any collection of wild animals in confinement should be threefold; first, to conduct as complete as possible a biological study of every species, especially those aspects which are too difficult or too costly to study in the wild and which may help in the preservation of that species in its natural habitat; second, to aid severely endangered species by setting up, under ideal conditions, protected breeding groups and, eventually, a reintroduction programme, so helping to ensure their future survival; thirdly, by the display and explanation of this work to the public, to persuade people of the vital necessity and urgency for the overall conservation of nature.”

“I said I liked being half-educated; you were so much more surprised at everything when you were ignorant.”

“The Mockery Bird regarded him with a roguish eye, head on one side, and took a few slow steps into the clearing. With its head on one side and its foot tentatively raised, it seemed like some sort of lanky, avian dancing master. It stepped forward among the guava stems with a mincing delicacy and then shuffled its wings like someone shuffling a pack of cards. He noticed that it had very long eyelashes which it raised and lowered over its large gaily-sparkling eyes. … There was another complicated rustle and flurry in the undergrowth and then, projected into the clearing by its own nervous eagerness, came a female Mockery Bird making strange, peeting noises, which became a soothing babble when she caught sight of the male. She went up to her mate and briefly preened his throat feathers as an over-zealous wife will straighten the tie of her consort. … Here in front of him, cossetting each other, were two birds which were thought to be extinct.”

“His pen squeaking like a demented wren as he wrote copious notes.”

“Right in the Heart of the African Jungle a small white man lives. Now there is one extraordinary fact about him that he is the friend of all animals.”

“There would be a dreadful outcry if anyone suggested obliterating, say, the Tower of London, and quite rightly so; yet a unique and wonderful species of animal which has taken hundreds of thousands of years to develop to the stage we see today, can be snuffed out like a candle without more than a handful of people raising a finger or a voice in protest. So, until we consider animal life to be worthy of the consideration and reverence we bestow upon old books and pictures and historic monuments, there will always be the animal refugee living a precarious life on the edge of extermination, dependent for existence on the charity of a few human beings.”
