Eastern osprey diurnal birds of prey, toes are of equal length, its tarsi are reticulate, and its talons are rounded, rather than grooved. The eastern and western osprey ("Pandion") and owls (Strigiformes) are the only hunters whose outer toe is reversible, allowing them to grasp their prey with two toes in front and two behind. This is particularly helpful when they grasp slippery fish. The states and territories of Australia where the species is recorded as occurring are Western Australia, the Northern Territory, Queensland, South Australia and Tasmania, The range is a narrow strip at the coast and offshore islands, although it
Evolution of birds teeth and sharp claws on the manus. The modern toothless birds evolved from the toothed ancestors in the Cretaceous. While the earlier primitive birds, particularly the Enantiornithes, continued to thrive and diversify alongside the pterosaurs through this geologic period until they became extinct due to the K–T extinction event. All but a few groups of the toothless Neornithes were also cut short. The surviving lineages of birds were the comparatively primitive Paleognathae (ostrich and its allies), the aquatic duck lineage, the terrestrial fowl, and the highly volant Neoaves. Modern birds are classified in Neornithes, which are now known to have
