Physical description Click here for a physical description Blue Bonnets are small to medium-sized parrots. There are races that have slightly different plumages. The features common to all races are dark-blue cheek patches with white lining, a brownish-grey chest and back (from the cap to the rump) and a greyish-brown uppertail with blue and white lining and a whitish undertail. Race "narethae" has a green frons, all others have a blue frons. Race "narethae" has a yellow belly and red vent, race "haemathorrhous" has some yellow too, but more red on the lower part of the belly and race "haematogaster" has a pale-yellow belly with a red patch in it and an amber vent/undertail coverts. The wings of the various races have different shades of ochre, red and orange in them, with some having small turquoise shoulder patches, but all have a deep-blue leading eadge and brownish-grey coverts. Females of race "haemathorrhous" show scalloping on the wing panels and belly, where males are solid-red. The bill of all races is light-grey, the irises are dark and the legs and feet are grey. Blue Bonnets, when seen from behind in rank or seeding grass, are almost invisible because of their superb camouflage.

Taxonomy, classification See Blue Bonnet at Wikipedia .

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Blue Bonnet parrot is available HERE . NB: Reports on ebird of birds submitted by birdwatchers from the Australian Outback tend to be clustered along roads and public areas such as camp grounds; in such cases their distribution is not a good representation of the overall distribution of the species. Blue Bonnets are endemic to Australia. They are well-adapted to life in the semi-arid interior of the Australian continent. All four races are found mostly inland, in the south-eastern quarter of the continent. Nominate race "haematogaster" is found in the south-eastern quarter of SA and the Murray River catchment, down to north-western VIC. Further North in NSW, in the Darling River catchment and into southern QLD, race "haematorrhoa" is found. They both connect with the range of race "pallescens", which is present only in the Lake Eyre Basin, in the border region of SA with QLD and NSW. Race "narethae" is found in two small patches in the Nullarbor, in South-East WA, just off the South coast, near the border with SA. Blue Bonnets are usually found around dry open woodland, often with grassy undergrowth, and in open grassland. Where to look? How to find this species? Blue Bonnets are very shy and therefore hard to approach. The way one can usually find them is when they are flushed while feeding in open grassland. They will usually fly into nearby trees. They usually don't go close to human habitation, but they can be found in farmland with scattered trees.

Sightings Click here for sighting information Race "haematogaster" M. Eaton reports finding Blue Bonnets, race "haematogaster", at Bowra Wildlife Sanctuary, near Cunnamulla, QLD, in September 2017. R. Plumtree spotted Blue Bonnets, race "haematogaster", at Bowra Wildlife Sanctuary, near Cunnamulla, QLD, in September 2017. We found Blue Bonnets, race "haematogaster", at Lake Bindegolly NP, near Thargomindah, QLD, in June 2019. Race "haematorrhoa" Although Blue Bonnets, race "haematorrhoa", are seen in the Narrabri area quite regularly, their distribution is patchy and their numbers in the foothills of the Great Dividing Range are small. In some areas of Eulah Creek, 20 km East of Narrabri, NSW, Blue Bonnets, race "haematorrhoa", can be seen regularly. This location in the foothills of the Nandewar Range is near the eastern boundary of their range. Towards the plains of inland NSW, westward of Narrabri, but also in other areas of the North-west Plains (e.g. Bellata, Moree and Maules Creek, NSW) and around the fringes of the Pilliga scrub, Blue Bonnets, race "haematorrhoa", are common. H. Mouritsen reports spotting a pair at Narrabri Lake, NSW, in October 2015. Blue Bonnets, race "haematorrhoa", were seen by us in various locations in outback NSW in September 2012. M. Eaton reports finding Blue Bonnets, race "haematorrhoa", at Bowra Wildlife Sanctuary, near Cunnamulla, QLD, in September 2017.

Blue Bonnets are the shiest parrots in our area that we have spotted so far. Being exclusively ground-feeding, they are vulnerable to attacks by predators.

Our observations in the Narrabri area suggest that Blue Bonnets live in small family units of up to about 10 birds; larger groups/flocks have been seen by us further inland.
