The birdlife of Codfish Island

The birdlife in December, 1966, is recorded in detail. Predation by the weka, particularly on nesting sea-birds, is noted and discussed; and the mammalian life, both native and introduced, is described. A brief outline of the early history of the island, and a general description of the topography and vegetation are included. A possible reason for the total absence of some species of birds is suggested. The value of the island as a future sanctuary for rare species is discussed.
