It is the eye of a parrot. Can't name the species. Might be a similar bird such as a parakeet.
The true parrots are about 330 species of bird belonging to the Psittacidae family, one of the two "traditional" families in the biological order Psittaciformes (parrots). The other family is the Cacatuidae (cockatoos) which are also parrots, but not classified as true parrots. True parrots are more widespread than cockatoos, with species in the Americas, Africa, Asia, Australia and eastwards across the Pacific Ocean as far as Polynesia.
The true parrot family is often considered to contain two subfamilies, the Psittacinae (typical parrots and allies) and the Loriinae (lories and lorikeets). However, there are other systems of classification and these two groups are sometimes ascribed full family status, being called Psittacidae and Loriidae.
Like most parrots the Psittacidae are primarily seed eaters. There is some variation in the diet of individual species, with fruits, nuts, leaves and even insects and other animal prey being taken on occasion by some species. The lorikeets are predominately nectar feeders; many other parrots will drink nectar as well. Most Psittacidae are cavity nesting birds which form monogamous pair bonds.
