General Species Information:
Found in the Murray Mallee SA, Coastal Areas and possibly elsewhere
You can see here this is a marked difference in the colouration between adults & juveniles; with the juveniles being a sooty grey colour, while the adults are stark white and grey/black.
There is a very similar introduced/cosmopolitan species, the Kelp gull (Larus dominicanus). Still quite rare in SA fortunately, and generally only found in the very south east & Kangaroo Island. The most obvious difference being that this one, the native species, has red on both the upper & lower beak; along with a black line on the upper beak.
