Our Impact

"CFO's generous gift is making a significant impact for the conservation of grassland birds. It's enabling the installation of a permanent Motus station that will track birds as they migrate across the Great Plains. CFO funding is restoring 346 acres of key habitat that benefits wintering birds in Chihuahua.
