||27 cm. Blue-and-green parrot with racquet-like tail extensions. Male has blue head grading into green breast. Rest of plumage bright green, darker on upperparts (especially wings) and yellowish on vent. Whitish-grey bill. Female similar though blue confined to crown and ear-coverts. Similar spp. Blue-naped Parrot Tanygnathus lucionensis is larger, lacks racquets and has red bill. Voice Raucous squawks interspersed with screeches and musical phrases. Hints Most often seen in rapid flight. Unobtrusive and difficult to see when perched.

Extensive lowland deforestation has resulted in the severe fragmentation and on-going decline in the extent and quality of suitable habitat in this species's small range, which, combined with limited exploitation for the cage-bird trade, is causing a rapid population reduction, thus qualifying it as Vulnerable. It is predicted that these threats will continue to cause rapid declines in the near future.

|Range Description:||Prioniturus platenae is endemic to Palawan and its satellite islands in the Philippines (Collar et al. 1999), where it is widespread in all mainland municipalities (P. Widmann in litt. 2012). Since 1980, there have been records from seven satellite islands (Calauit, Busuanga, Culion, Dumaran, Rasa, Pandanan and Bugsuk). It reportedly used to be relatively abundant, but the recent paucity of records indicates that it has declined and become generally uncommon, although it still occurs regularly in small numbers at several sites (P. Widmann in litt. 2012). |

|Population:||The population is estimated to number 2,500-9,999 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.|
Trend Justification: The lack of recent information regarding this species precludes making strong assertions about its current trend, but the threats of logging, mining and trapping suggest the species is declining rapidly.
|Current Population Trend:||Decreasing|
|♦ Number of mature individuals:||1500-7000||♦ Continuing decline of mature individuals:||Yes|
|♦ Extreme fluctuations:||No||♦ Population severely fragmented:||Yes|
|♦ No. of subpopulations:||2-100||♦ Continuing decline in subpopulations:||Unknown|
|♦ Extreme fluctuations in subpopulations:||No||♦ All individuals in one subpopulation:||No|
