Al Larson is a 97-year-old birdwatcher from Idaho who has built and placed more than 350 wooden nest boxes throughout the state's southwest. He started the project in the late 1970s after reading how important the shelters are to the survival of bluebirds. Today, at the age of 97, he is still at it. Larson monitors the little houses to record vital data about the number of eggs and nestlings. To date, Larson has helped fledge over 40,000 bluebirds.
