The Orioles will once again run our traditional Birdathon route, an epic all-day quest for birds in the Santa Catalina Mountains! On April 29 we'll bird Tucson's own "sky island" mountain range from bottom to top over the course of one long day, and aim to see a selection of the representative bird species found in each life zone as we go. We'll start at dawn with riparian habitat along Tanque Verde Creek and then bird the Sonoran Desert at the foot of the mountains before continuing upward through the oak, pine, and fir forests toward the top of the mountains. Our target is to see and/or hear 100-120 species throughout the day.

The Orioles Birdathon team for 2023 is Scott Olmstead, Carl Englander, Will Russell,  Malcolm Chesworth, and Tony Shrimpton.

**Update: We finished the big day with a solid 104 species, with one of the top highlights being the rare Evening Grosbeak in Summerhaven.**

ABOUT Birdathon 2023



Birds have a unique, special, and different meaning to each of us. So, too, is each of our connection with Tucson Audubon Society personal and distinct. During Birdathon, we combine the love of bird watching during spring migration with support for bird conservation.

Birdathoners are birders and social fundraisers, joining together to make a difference for the birds and habitats of Southeast Arizona. Birdathoners continue a tradition that has held strong for over 30 years! 

Each Birdathoner's personal network of supporters is what helps makes Birdathon possible. 

Birdathon donations are tax deductible to the extent allowed by law. Tucson Audubon Society is a 501(c)(3) nonprofit.
