Factual error: There are a few things wrong with the swan egg that Maya has found. First, in the opening scene we see that the egg is a hard-shelled egg, and it appears much too large for a swan egg. Second, at the end of the film, the egg hatches to reveal a baby alligator. Alligator eggs are soft shelled. Third, alligators are not native to San Francisco, but the southeastern United States.
