Colophon
The animal on the cover of Designing Voice User Interfaces is a blue-headed Pionus parrot (Pionus menstruus). This bird inhabits forest canopies throughout tropical South America and southern Central America.
In addition to the blue head and neck for which it is named, the Pionus sports green, iridescent plumage and red feathers under its tail. Most of these parrots grow to about 11 inches long.
Pionus parrots are not particularly talkative, but prone to making high-pitched screeching calls. Still, they are considered to be calm and quiet compared to other parrot species. Highly intelligent and sociable, they make popular pets. While its lifespan averages 35 years, some survive as long as 60 years.
