Tom Wood and Sheri Williamson, co-founders of the Southeastern Arizona Bird Observatory

SABO was founded in 1996 by Naturalist/Directors Tom Wood and Sheri Williamson with the able and enthusiastic support of volunteer Director Mark Newstrom, a birder and bird bander with more than 30 years experience in Arizona. Mark’s wife Michelle Cook, an owl bander and raptor rehabilitator, joined the board a few years ago. With the acquisition of Ash Canyon Bird Sanctuary in November 2019, SABO’s board expanded to include  Olga Harbour and Richard Carlson of Tucson, Arizona.  We’re grateful for the experience, expertise, and enthusiasm that our board members and advisors bring to the table.

The work we do would be impossible without a cadre of passionate and hard-working volunteers. Our 2024 hummingbird banding team included Warren Hoffard,  Tommy and Julia McDonald, Linda and Chris Hanson,  Rebecca Hooker, and Karen Parker. Our resident volunteer caretakers at Ash Canyon Bird Sanctuary are Tim Blount and Kristy Reske, aided by a growing list of day volunteers.
