Answer

In birds, uric acid is created in the elimination of nitrogenous wastes rather than in response to purine intake.

Work Step by Step

See the answer to the previous question. Birds use uric acid to eliminate nitrogenous waste, whereas humans have no such a metabolic process. For us, a reduced purine diet would have a direct effect on uric acid in the body. For birds, this is not the primary source of uric acid and would not have an effect.
