What was the name of Thomas Jefferson's mockingbird?

The name of his bird was Dick and is the only one mentioned by him in his diary in 1806. [I too, remember Dick being written about. Dick was famous for saying, "wanna towel, wanna bath, and more 'oap?" Dick was a Mockingbird; a constant companion, even when ambassador to France, Dick traveled with T. Jefferson. When President, Dick was well known to visitors.]
