Mockingjay Bird.
A mockingjay is a bird that was created through inadvertent cross-breeding of jabberjays and female mockingbirds.
Origin
A hybrid of mockingbirds and jabberjays, the birds were created by mistake. The jabberjays - all male - were initially created to eavesdrop on the rebels in the dark days, memorizing entire conversations and repeating them back at the Capitol. Once they were discovered, the rebels fed endless lies to the birds, and sent them back loaded with false information. After the lies were discovered, the Capitol closed the laboratories and the jabberjays were released into the wild, in the hope that they would die off. They did, eventually, but not before they passed on their genetic code to female mockingbirds. This was unforeseen, because no one expected them to be able to reproduce with other bird species. The offspring were called mockingjays, and, while they had lost the ability to memorize words, they could mimic any sounds from a child's high-pitched warble to a man's deep tones.
Talents
Like their jabberjay fathers, mockingjays are excellent mimics, and have the ability to memorize and repeat both bird and human songs. They can perfectly copy down to the last note, any human tune. They pick up tunes quickly, and often spread them to other mockingjays. However, they only sing the songs of those whose voices they enjoy.
Habitat
Mockingjays are described as being as tough as rocks, being able to thrive in almost any environment.
