I don't think the Nazgul did much. Apart from crying and demoralizing the Gondorians in the few days before the battle, and twice pursuing Faramir when he retreated to the city, they did not intervene. The pursuit of Faramir was too fast for the Eagles to come from the North, and otherwise there was no need of their help. Also the Eagles did not just come on Gandalf's call. How would he contact them? Gwaihir was sitting in his nest, Gandalf was seven hundred miles away. And the Eagles could as well serve their purpose by getting rid of the mountain goblins. Mainly, the battle at Pelennor was not a battle where the Eagles could - by logic - be of much use. They could not attack the hosts in plains, at maximum they'll get shot down. They were not close to the Gondorians in any way. So, I think it would be weird if they came.
