There are roughly 398 species of parrots in the world, living mostly in tropical climates. They are found natively in Australia, South and Southeast Asia, Central and South America, Africa, and some Caribbean and Pacific islands.
Almost all parrots nest in tree hollows and lay white eggs. The most obvious physical characteristics of parrots is vivid coloring and a strong, curved, broad bill.
Parrots are among the most intelligent birds, and some species can imitate human speech. (They do not have vocal cords, so sound is created by moving air across their trachea.) Certain parrots even can use simple tools and solve puzzles.
