California Fall Challenge 2023

Help engage communities in avian science, habitat restoration, & education!

The California Fall Challenge is SFBBO's biggest annual fundraising campaign each year! Our goal is to raise $40,000 to fund our work to carry out our new three-year Strategic Plan to Inform, Inspire, and Involve diverse communities in our mission to promote sustainability in the Bay Area and beyond.  


Donations of $80 or more are eligible to receive a 2023 SFBBO t-shirt. The estimated value of the t-shirt ($15) is not tax deductible.  Please visit our website to view the Shirt Size Charts.


The artwork (at right) was designed by Marina Dimitrov and is on a black shirt. The owls showcased on the shirt - Burrowing, Short-eared, and Great Horned - have a lot to teach us about sustainability. As apex predators, they are both vulnerable to climate change, habitat loss, and other environmental issues and their presence plays a critical role in helping ecosystems stay in balance. Their direct gaze and charismatic beauty connect us to nature and inspire us to continue our work. By wearing our shirt, you can help tell the story of birds to your community and invite others to get involved. Marina works as a Visitor Experience Manager at the Seymour Marine Discovery Center in Santa Cruz - when she is not dabbling in illustration on the side! 


We have the following shirt styles and sizes available: Women's Relaxed Fit Small, Medium, Large, and XL and Unisex Small, Medium, Large, XL, and XXL. We are taking pre-orders in September and October and will be printing and mailing out the shirts in November 2023. If you are interested in a shirt, after you make a donation please write to [email protected] and let us know what style and size you would like. These shirts will not be available after October 2023, so order yours today!


More fun California Fall Challenge events are scheduled for September and October including great speakers, our Band-a-Thon, and an Online Silent Auction. Check them out.  Thank you!
