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
Origin of birds between "Archaeopteryx" and modern birds, phylogenetic taxonomists, in keeping with tradition, almost always use "Archaeopteryx" as a specifier to help define Aves. Aves has more rarely been defined as a crown group consisting only of modern birds. Nearly all palaeontologists regard birds as coelurosaurian theropod dinosaurs. Within Coelurosauria, multiple cladistic analyses have found support for a clade named Maniraptora, consisting of therizinosauroids, oviraptorosaurs, troodontids, dromaeosaurids, and birds. Of these, dromaeosaurids and troodontids are usually united in the clade Deinonychosauria, which is a sister group to birds (together forming the node-clade Eumaniraptora) within the stem-clade Paraves. Other studies have proposed alternative
