Cool thread. Yeah I thought of the Mockingbird too. It 'mocks' the songs of other birds. It is the ultimate bird impressionist. It does this to impress its potential mate. The more songs in its repertoire the more likely it is to snag a mate. Mockingbirds are a joy to listen to. I once heard one go about 15 minutes before he ran out of material. I'm pretty sure that one was the stud of the bird world that night - LOL.
