The jabberjay is a type of bird that was created to spy on enemies of the Capitol. Jabberjays had the ability to memorize and repeat whole human conversations, and were used to eavesdrop on the rebels. Once the people in the districts realized how their private conversations were being transmitted, they used the jabberjays to feed lies to the Capitol. Once they noticed this, the Capitol abandoned the jabberjays leaving them to die. But the jabberjays mated with mockingbirds creating mockingjays. Jabberjays are a rare sight but they can be chillingly accurate with their voices. They can mimic howls, cries, and pretty much any noise. They were described as black and crested, similar to the mockingjays.
