There were at least three Scarlet Robins, with a male and possibly two females. The male was calling but the females were not making any sound. The male would sometimes fly to a branch, land, call and depart. The female would then land on the branch. I cannot be certain but these birds, or another group of Scarlet Robins, ranged over about 200 metres, only going to trees about 20 meters either side of the small, almost dry creek. The last tree I saw them in was the larger eucalyptus beside the small dam.
