Editor's note: Fifth in a weekday series on the personal traits, tastes and backgrounds of presidential candidates.

WASHINGTON - Meet the presidential candidates by another name - Barry, Bird Legs, Coyote Bill.

Such are their childhood nicknames.

Several of the candidates go around today with names altered in their youth. Mitt Romney, for example, was named Willard Mitt Romney. In a twist from the usual nickname progression, Fred Thompson actually was named Freddie, and John Edwards was named Johnny.

Rudolph Giuliani is running under the less formal Rudy, the name by which his friends and close associates have known him for decades.

Behind those modest alterations are a few truly fanciful monikers. They emerged when AP asked them about their childhood nicknames in a series of questions about their personal side. Thompson's campaign, in response, indulged in a touch of whimsical wishful thinking.

The candidates by their full names, and their nicknames:
