Pionus are a rather well-kept secret. Those who are spoiled as they deserve BLOOM. Others remain so withdrawn in captivity that they've gained a rep as perch potatoes. They can take awhile to warm up to a new person, so they don't make the good impression at point of sale that many friendlier parrots do. They're not known for their ability to speak human language, but mine greet me with an enthusiastic
"Hi babe!" when I behave. Here's a profile of a properly indulged white-capped pi:
http://parrotstrut.com/MeetCookie.htm Mine are a 12yo pair who bonded before their first birddays. They raised babies years ago, but now recreational sex is a favorite activity. Many times one or the other can only be moved via hand-held perch, and other times both are on my matching shoulders, nibbling my ears, preening my hair, and pooping down my shirt.
I always recommend females because pi are exceptionally territorial birds in the wild. The female tends the eggs and chicks, while the male brings food to her and protects his family. In our climate-controlled homes, their sexual hormones can surge year-round, and humans who aren't careful can learn first-hand about the strength of their beaks and their snapping turtle habit. The females are no shrinking violets, but they are usually peaceable far more often than the males. Some insist on laying eggs tho. That can get worrisome in captivity.
Mine are dusky pi and well loved. I hope you make a good decision for yourself and the little pi in need of a new home. I have no idea about the $800 price. Too many variables.
