One name used to describe such intergrading birds is “wheat-belt hybrids” -- in other words a hybrid between the 28 and the Port Lincoln occurring on the fringes of wheat-belt farming areas where it meets heavier timber habitat.


SHADES OF GREEN:


What is obvious to my eyesight is the difference in green appearing in the Port Lincoln and the 28. With the larger 28 type birds either totally green or with sometimes very small amounts of yellow in the abdomen I observed that the green of the back and chest varies across a wide range of shadings. My darling supervisor says that overall it is a yellowish-green. I guess this is a fair enough description when compared to Port Lincolns of the southern form whose green on their back is different while the chest is really dark dark emerald green.


MY LOCALITY:


I am located 45 km east of the Western Australian coastline in the Darling Escarpment, this is classed as a Mediterranean climate and temperatures vary from the occasional night temperature as low as six degrees C in winter rising to mid 40C daytime at the height of summer.

BIRD SCENE 39


Birds that closely fit the description of the twenty eight as well as the hybrid Port Lincoln/28 visit my property regularly and I occasionally see birds that are closer to the Port Lincoln characteristics.
