We all want our pets to be comfortable in the summer. An economical way to cool you and your bird is to arrange a fan to blow air  over your bird's cage. Great for dogs but the problem is that you'll be constantly disrupting their complex feather system.

When feathers are "ruffled" a birds first inclination is to preen (clean) and try to keep the feathers in place which can lead to over preening and possibly feather destruction and/or self mutilation.

If possible use indirect airflow to avoid this problem.
