Vulturine parrot

The vulturine parrot (Pyrilia vulturina), not to be confused with Pesquet's parrot (Psittrichas fulgidus), is a Neotropical parrot, which is endemic to humid forest and adjacent habitats in the eastern Amazon of Brazil.[2]

Taxonomy

Until recently, it was placed in the genus Pionopsitta, which now is restricted to the type species, P. pileata. Furthermore, individuals previously believed to be immature vulturine parrots were described as a new species, the bald parrot (Pyrilia aurantiocephala), in 2002.

Description

The vulturine parrot has a total length of c. 24 centimetres (9.4 in). It has a rather short, squarish tail, and a mainly green plumage, which typically is tinged blue, especially below. The chest is olive-brown. The underwing coverts are bright red, and when perched this can be hinted as an orange-red shoulder-patch. The under-tail is yellowish with a bluish tip (appears dark against light). The outer webs and tips of the remiges are bluish-black, making the outer sections of the upperwing appear quite uniformly dark in flight. The arguably most conspicuous feature, however, is its un-feathered blackish and orange-pinkish head, bordered by a broad yellow collar of feathers, followed by a second blackish collar. This bare, vaguely vulture-like head is the reason behind its common name. Juveniles have a feathered greenish head.

Little is known about its behavior, but it is suspected the bare head is an adaptation to avoid feather-matting from sticky fruits. It has also been recorded feeding on seeds and berries.

gollark: > A core proposition in economics is that voluntary exchanges benefit both parties. We show that people often deny the mutually beneficial nature of exchange, instead espousing the belief that one or both parties fail to benefit from the exchange. Across 4 studies (and 7 further studies in the Supplementary Materials), participants read about simple exchanges of goods and services, judging whether each party to the transaction was better off or worse off afterwards. These studies revealed that win–win denial is pervasive, with buyers consistently seen as less likely to benefit from transactions than sellers. Several potential psychological mechanisms underlying win–win denial are considered, with the most important influences being mercantilist theories of value (confusing wealth for money) and naïve realism (failing to observe that people do not arbitrarily enter exchanges). We argue that these results have widespread implications for politics and society.

gollark: I mean, *maybe* some behaviors make sense at population scale or in some bizarre game-theoretic way?
