The Ruddy Turnstone (Arenaria interpres) is a small wading bird, one of two species of turnstone in the genus Arenaria. It is now classified in the sandpiper family Scolopacidae but was formerly sometimes placed in the plover family Charadriidae.
Also named “seagull” and very common in Australia. I know… it's not a crocodile (but yes it also attack!). For crocos., don't worry, pictures will be posted right there on my gallery!
