The blue-winged racket-tail or Sulu racquet-tail (Prioniturus verticalis) is a species of parrot in the family Psittaculidae. It is endemic to Tawi-Tawi island in the Philippines and is one of the most endangered parrots in the world. It is threatened by habitat loss and the poaching for the cage-bird trade.
It has mainly dark green plumage on back, an olive/green on its breast and belly. Male birds have a pale blue with small red patch on its forehead and forecrown. Females look identical to the male except, they do not have a red spot on their forecrown. The primary feathers blue on outer webs while the middle tail feathers green. Racquet feathers black tinged with blue. Their side tail feathers are green tipped black. Their bill has a blue-grey hue.
Most similar to the Montane racket-tail but forehead, sides of head and nape are green. Females also have less blue on their face compared to the Montane racket-tail.
The security situation in the Sulu archipelago has prevented researchers from studying this bird. It is pressumed to have a similar diet as all other racquet-tails, feeding on fruit, particularly bananas, flowers and seeds of growing corn, and rice.
Its breeding season is believed to be from September to January. Like all other parrots, it is a cavity nester. A single nest was recorded in a large broken off palm tree in a grove of palms beside a forest. [2]
Its natural habitats are tropical moist lowland forests and subtropical or tropical mangrove forests. It is now assessed as Critically Endangered by the IUCN Red List with population estimates being just 50 - 249 mature individuals. [1] Its main threat is habitat loss and trapping. Once prevalent throughout all the islands of the Sulu Archipelago, the blue-winged racket-tail is now only found on isolated places on Tawi-Tawi due to rapid habitat destruction during the past 200 years. [3]
One of this bird's threats is its own tame behavior. This tame behavior is taken advantage of by trappers and has made it an easy target to capture for the illegal exotic pet trade. Deforestation of the blue-winged racket-tail's natural habitat to make way for both legal and illegal logging agriculture, mining, and the uncontrolled settlement by humans has destroyed most of this bird's original habitat.
The lilac-crowned amazon, also known as lilac-crowned parrot, Finsch's parrot or Finsch's amazon, is a parrot endemic to the Pacific slopes of Mexico. Also known as Finsch's amazon, it is characterised by green plumage, a maroon forehead, and a violet-blue crown and neck.
The green racket-tail is an endemic parrot of the Philippines where it is found on Luzon and Marinduque. This species was once common, but is rapidly declining and is currently classified as endangered due to lowland deforestation and capture for cage-bird trade. The population is now estimated to be just 1,000 - 2,499 mature individuals and is continuing to decline with many local extinctions in its former range.

The lower wings and back are varying shades of brown, and the throat and chest are largely white. The belly is an ashy-gray.

It is becoming rare due to habitat loss and trapping for the pet trade.
