vegetation is open and in many cases sparse, in this area can be found the arid zone birds. With the variation in climate there is also variation in the vegetation. Creeks and rivers that provide drinking water flow through different rock strata altering the types of shrubs bushes and trees. All of these factors can have an influence on the shape, physical characteristics and even colour of a race of birds that cover such an enormous area. For the reasons mentioned previously a simple description would be to class the Port Lincoln as northern or southern form and within the southern form are those birds termed twenty eights.


WHERE TO GO FOR SPECIMENS? The most appropriate location for me was the WA Museum, during a previous investigation that I performed -- purely on the twenty eight -- I had the opportunity to examine hundreds of specimens of


birds of this Western Australian ring- neck family. These museum specimens have been obtained -- then collated over time – throughout large areas of WA”, to me what was obvious was the enormous range of sizes and colour forms appearing in those examples.

Port Lincoln has a really dark green chest, c stomach, generally smaller than the 28 – a almost equaling the 28 in size.
