Who is Jon Wood in Frightful's Mountain?

Jon Wood, married to Susan, has spent his life raising, hacking, and healing injured and orphaned birds. He and his wife are described as incredibly kind and gentle, and together, they cared for Frightful after she was electrocuted. They also spend much of their time visiting schools, showing them falcons - including Frightful, who becomes a symbol of a cause, inspiring the kids to write letters to the power companies, urging them to make utility poles animal-friendly.
