Betty's bluebirds
Betty Cunningham tends to the bluebirds at Tinker Golf Course every week, checking on the mothers and their eggs. She records how many eggs are laid and how many are hatched and sends a report to the Oklahoma Department of Wildlife Conservation. She and her late husband, Dean, have fledged more than 800 bluebirds since the inception of the Nest Box Trail project in 1989. (Air Force photos by Kimberly Woodruff)
