The California Fall Challenge is SFBBO's biggest annual fundraising campaign and this year is extra special because we are celebrating our 40th Anniversary!
Our goal is to raise $40,000 to support our work throughout the year and we hope you will participate and help us to reach our goal!
Donations of $75 or more are eligible to receive a 2021 California Fall Challenge T-Shirt (at right).
This year's 100% cotton, water-based ink, Leaf Green shirt is a beautiful multi-colored design created by artist Julie Ho that depicts 40 birds for 40 years. The estimated value of t-shirt ($20) is not tax deductible. Learn about all the species showcased on the shirt and their connection with SFBBO's work on our blog.
