Swing bridge by Cleopatra Pools track. Duck swooped in and landed on the bridge. Then followed us along the track to the pools approx 750m then back again to the junction of the bridge. It became very aggressive and attacked me on the legs by pecking and hanging on to my legs and thumping with is webbed feet. We thought maybe there was a nest close by but didnt see any other ducks or ducklings. We didnt feed it.
