bill, a useful bit of information often omitted in bird books. Also included are brief sections on Habits (again often omitted in bird books), Voice (if heard in Hong Kong), Habitat, World Range, and Records for Hong Kong (where, when and how frequently seen).
A lecture given by Major Macfarlane in 1960 to the Hong Kong Branch of the Royal Asiatic Society is reproduced. This shows the distinctive features of Hong Kong as seen by the bird watcher, such as its wide range of habitats within a small area and the fact that being on the northern limit of the tropics it is in a zone where northern birds and tropical birds overlap to some extent. It is also on a migration route and in spring or autumn one may see many species on their way to or from their breeding grounds in the Arctic.
The illustrations in black and white by Commander A. M. Hughes are excellent and there is also a useful map at the end showing most of the places mentioned in the book. It is clearly printed on good paper and will fit easily into the pocket.
Another very useful feature is a chapter on bird-watching areas by J. L. Cranmer-Byng. It is easy in Hong Kong to walk in the country for some hours and see hardly any birds. One must know where to look and in describing the best areas Mr. Cranmer-Byng makes clear the threat now faced by the ever "encroaching tide of human activities" which has already driven many birds out of places where they were abundant in Dr. Herklots' time. It is suggested that eventually Hong Kong will need to establish a Nature Reserve. Surely the need is for a Nature Reserve now. In a few years' time it may not be possible to find a large enough area which would be suitable.
It has been a pleasure to review this excellent little book on which Miss Benham, her collaborators and her publishers are to be congratulated. If you already know something about birds in another part of the world it will enable you to get to know the rich variety of birds to be found in Hong Kong. If you know little about birds but would like to know more it will almost certainly entangle you irretrievably in an absorbing hobby which will give lifelong pleasure.
