The eastern bluebonnet (Northiella haematogaster), also known as the greater bluebonnet, is an Australian parrot, one of two species in the genus Northiella. It was originally included in the genus Psephotus but due to distinctive physical and behavioural differences was reclassified into its own genus in 1994 by ornithologists and taxonomists Christidis and Boles. The bluebonnet is a medium-sized inland parrot commonly found in the interior of southeastern and central-southern Australia. It is adapted to life in semi-arid regions but can also flourish in regions of medium rainfall towards the eastern and southern extremities of its range.
The eastern bluebonnet is a medium-sized parrot with prominent crest-like head feathers. All bluebonnets have a mostly olive-grey to brown upperbody, foreneck and breast, with the outerwing and leading edge to the folded wing being dark blue, a blue forehead and face. The bill is pearl grey, the cere is light grey, iris colour is brown-grey, and the feet and legs are dark grey. There is no seasonal variation in the plumage and there are no similar looking species to the bluebonnet parrot.
