The Chattering Lory, Lorius garrulus, comes from North Maluku, Indonesia. As its name indicates, it is vocal.
There are three subspecies: the nominate species above is red with green wings and thighs, yellow at the top of the wing and a fully red back or sometimes just a tiny yellow spot on the upper back.
The undertail has yellow with red.
The Morotai Yellow-backed subspecies, L. garrulus morotaianus, can have yellow on its back but less than the Yellow-backed below.
The more usually seen subspecies in captivity is the Yellow-backed Chattering Lory, L. garrulus flavopalliatus, with a large yellow diamond-shaped patch on its upper back.
The top of the wings is usually a brighter red and less extensive yellow, as shown above left and centre rather than those above right and below.
