While logical, this statement is not strictly true. There have been
studies done in Texas of mockingbird songs which showed that Texas
mockingbirds were imitating the songs of tropical birds found much
farther south. Since mockingbirds don't migrate, you wouldn't expect
this. What they learned from the study is that mockingbirds were
passing the songs farther and farther north between themselves. Sneaky
little mockingbirds!
