There are about 17 species of mockingbirds. 13 of these are ranked by IUCR as "Least Concern" (IUCR-speak for "there's tons of 'em"). The ones which are not are the Socorro Mockingbird (Critically Endangered), the Hood Mockingbird (Vulnerable), the Floreana or Charles Mockingbird (Critically Endangered), and the San Cristobal Mockingbird (Endangered).
The Jabberjay is a mutation created by the Capitol, and it was used to listen in on the rebel conversations, and then repeat them for the Capitol in the Dark Days. When the rebels started feeding the capitol lies, the capitol abandoned the jabberjays, hoping they would become extinct. They eventually did become extinct, but not before they mated with mockingbird.
