Nest predation and the evolution of life history traits in New Zealand birds
Guest lecture by Prof. James Briskie, University of Canterbury.
Unlike birds in most continental areas, birds on many isolated and oceanic islands evolved in an environment with few predators. For example, until humans (and their cargo of pests) arrived about 700 years ago, the native birds in New Zealand evolved in the complete absence of all terrestrial mammals and snakes. The only major predators present were other birds. Islands like New Zealand thus provide an ideal situation in which to study how life history traits of birds vary with predation risk. In this talk, I will use the results from a variety of field studies to show how such low-risk environments appear to have shaped the behaviours and reproductive life histories of native birds in New Zealand. With exotic predators now firmly established on islands all around the world, including New Zealand, my studies also highlight how an understanding of the life history traits of island birds can help with their conservation.
