The Western Rosellas come in family groups of eight to twelve at a time. They search for seeds in the paddock or attack flowers in the trees. They often visit the chook run and inspect the ground that has been turned over by the chooks. If one bird is disturbed the whole flock will take to the air and settle well up in the trees watching the surroundings.
They have a habit of crashing into our windows. Occasionally they will knock themselves unconscious for a few minutes but usually they just pick themselves up and fly away immediately.
