Azure-rumped parrot
The azure-rumped parrot (Tanygnathus sumatranus) is a large bird endemic to Indonesia. It is found in Sulawesi and the Sangir Islands. It was previously conspecific with the blue-backed parrot, which is differentiated with its red iris and blue back versus the azure-rumped parrot's yellow iris and plain back. It is found in forests. Flocks are small and often active at night. Its main threats are habitat loss and trapping for the pet trade.

Taxonomy
There are two subspecies:[2]
- Tanygnathus sumatranus sumatranus (Raffles, 1822): Sulawesi. Sulawesi and nearby islands. Yellow iris.
- Tanygnathus sumatranus sangirensis Meyer, AB & Wiglesworth, 1894: Sangir Islands and Karakelong. More blue on wing bends and wing coverts, head darker green. Yellow iris
Previously, only sumatranus was recognized, but sangirensis was also recognized by the International Ornithological Congress in 2022 based on phylogenetic evidence.[3][4]

The head, mantle, wings and tail are darker green, the belly and collar are lighter green.
