“The entire destruction of its luxuriant native forests [Saint Helena Island] by the introduction of goats which killed all the young trees (a destruction which was nearly completed two centuries ago) must have led to the extermination of most of the indigenous birds and insects... Numerous imported birds, such as canaries, Java sparrows, some African finches, guinea-fowls, and partridges, are now wild.

There are no native butterflies, but a few introduced species of almost world-wide range”
