The Balcones Canyonlands Songbird Festival includes a collection of interpretive events designed to help participants experience a variety of bird species and their habitats. Experienced guides host bird walks on closed portions of the refuge and help birders from around the world add to their life lists. Registration is required for each event that you wish to attend and spaces are limited. The events are listed on the April calendar posted to the Friends of Balcones website, and there is a $100 registration fee for EACH event.
