 A more casual visitor to the mangroves at high tide is the eastern sea garfish ("Hyporhamphus australis") which scoots around just an inch from the surface and is virtually invisible unless viewed through a snorkel.Dozens of different bird species may be seen foraging in the rich mudflats in and around mangrove flats many of these birds being threatened with extinction and protected by international agreements.Commonly seen bird species include Eastern curlews ("Numenius madagascariensis"), striated herons ("Butorides striatus"), brown honeyeaters ("Lichmera indistincta"), little egrets ("Egretta garzetta"), royal spoonbills ("Platalea regia"), white-faced grey herons ("Egretta novaehollandiae"), Australasian little bitterns ("Ixobrychus dubius"), pied oystercatchers ("Haematopus longirostris"), Australasian pelican ("Pelecanus conspicillatus"), sacred ibis ("Threskiornis moluccus"), chestnut teal ("Anas castanea") and azure kingfishers ("Alcedo azurea").
