I have a reptile room filled with lizards and a snake. There are two play areas for the birds in the reptile room, and it is their favorite place to hang out and take naps. They are for the most part oblivious to the reptiles, though my Meyers is an idiot and likes to try and pester them. He will try to chew on their toes or tails, or steal food from the iguana. He also likes to cling to the fronts of their cages and stare at them while they are going about their business.
As long as you make sure that the reptiles and birds don't come in contact with each other you should be fine. Monitor the bird for any sign of stress around the reptiles, and alter as necessary. In my experience, the reptiles will likely pay no attention to the birds.
