They did an amazingly good job staying in our laps or sitting in their own seats.
And for the most part they were really quiet. Though 3 or 4 times in the movie when there was a split second of silence and there were none of the brightly colored birds in sight Connor would ask "Where did all the birds go!?"
The boys laughed at the birds antics and thoroughly enjoyed the movie theater popcorn. Particularly Ryan who I think polished off at least 3 cups all on his own. :)
