100-year-old Alfred Larson has gone through a lot in his lifetime， but one thing that keeps him going is bluebirds.

When Alfred retired in 1978， he wanted to find a hobby or something to do so that it would keephim busy and provide him with a sense of purpose. When he read a National Geographic article about crafting wooden nest boxes for bluebirds to help boost their populations， he decided to give it a try.

In an interview with Audubon， Alfred explained that he started building bird boxes on his ranch using leftover pieces of wood and scraps.

More than four decades has passed by， and Alfred is still going strong and promoting bluebird conservation efforts. Back in 2018 at 96， Alfred was monitoring nearly 350 nest boxes on six different trails in Southwest Idaho. Speaking with Audubon， he said， “I settled on a simple design that was easy to build and easy to monitor. I kept adding more boxes on these trails， and these birds responded.”That year， he banded over 900 birds. We can only imagine the impact he's made on the population over thespan（跨度）of the past over four decades.

To celebrate his accomplishments， film-maker Matthew Podolsky worked with Alfred for weeks to create a beautiful 30-minute documentary Bluebird Man. The film explores Alfred's upbringing and how everything led him to the work he does today. In the documentary， Podolsky said， “Alfred is a living example of how much one person can achieve when they set their mind on a task. But he's also an example of the benefits that a project like this can have for people. Bluebirds have given meaning to Alfred's life， and they are truly the secret of his longevity （長壽）.”

Alfred turned 100 in March 2022， and while he's not as active as he was a few years ago， he's still beaming with life. The impact he's had on the populations of bluebirds in North America will remain his legacy， long after he stops building boxes.
