THE spur-winged plover, Vanellus miles, has a distribution that extends from New Guinea along the east coast of Australia to New Zealand.
The wader self introduced to New Zealand in the 1930s, and has expanded its range in Australia as well as New Zealand over the last few decades.
Charles Darwin and Alfred Wallace suggested the current distribution and abundance of plant and animal species is a consequence of evolution rather than Divine intervention. Consequent to this is the idea that distributions will change, they are not constant.
While the theory of evolution by natural selection is now accepted by the mainstream as a best explanation for the diversity of life on planet Earth, the very recent preoccupation with temperature and in particular the idea that small changes in temperature may result in the extinction of particular species, does not sit well with their theories on the distribution of the many species with a very broad geographic range; like the spur-winged plover.
