Avian keratin disorder (AKD) is an emerging disease among wild birds in North America characterized by overgrowth and deformities of beaks. Cases were first observed among black-capped chickadees in Alaska in the late 1990s, and it has spread rapidly since then. [1]
Psittacine beak and feather disease was first described in the early 1980s and has become recognised as the dominant viral pathogen of psittacine birds worldwide. In wild red-rumped grass parakeets (Psephotus haematonotus), a case of feather loss syndrome that was highly suggestive of PBFD was first recorded in South Australia in 1907. [2]
Eclectus is a genus of parrot, the Psittaciformes, which consists of four known extant species known as eclectus parrots and the extinct Eclectus infectus, the oceanic eclectus parrot. The extant eclectus parrots are medium-sized parrots native to regions of Oceania , particularly New Guinea and Australia .

Parrots are small to large birds with a characteristic curved beak. Their upper mandibles have slight mobility in the joint with the skull and they have a generally erect stance. All parrots are zygodactyl, having the four toes on each foot placed two at the front and two to the back. Eclectus parrot, Eclectus roratus (I)
The oceanic eclectus [2] (Eclectus infectus) is an extinct parrot species which occurred on Tonga, Vanuatu and possibly on Fiji. Its closest living relative is the eclectus parrot ( Eclectus roratus sensu lato), which has proportionally larger wings than the oceanic eclectus parrot.
The Papuan eclectus is a popular pet parrot and there is a large avicultural population. [3] Many Papuan eclectus in captivity in Australia are apparently hybrids between subspecies E. p. polychloros and E. p. solomonensis, as Taronga Zoo Sydney had a flock of these two subspecies in a large aviary many years ago.
Rostrum (from Latin rostrum, meaning beak) is a term used in anatomy for several kinds of hard, beak-like structures projecting out from the head or mouth of an animal. Despite some visual similarity, many of these are phylogenetically unrelated structures in widely varying species.
