Royal Spoonbill
Platalea regia

Royal Spoonbills are one of two spoonbills in Australia, with the other being the Yellow-billed. They use their highly-specialised bills in a sweeping motion to probe mud for invertebrates, sometimes working line abreast. Royal Spoonbills are quite large birds (74-81 cm), but smaller than Yellow-billed Spoonbills.
