On March 5, Austin Water Utility’s Wildland Conservation Division volunteers Lila, Gloria, Chris, and Audrey led a group on a hike in the Butler Ecological Preserve, an area at the end of Jester Boulevard that is otherwise closed to the public. The beginning of the hike is down a wagon trail through shrubby live oak and evergreen sumac under power lines, suitable habitat for black-capped vireo. Lila stops to tell about the brown-headed cowbird trap before guiding us off the trail and through the woods. She notes that we are now walking through golden-cheeked warbler habitat, mature juniper and oak woodland, pausing on a rocky slope that is in fact a field of cretaceous era fossils. At the bottom of the slope is a running creek, and from the side of the creek bubbles Tenacio Spring, named for the previous caretaker of the land. The base of a tree trunk forms a fiercely guarding gargoyle above the spring. Then back up the trail, past a deep ravine we come to Kiki’s Spring, named for Kent Butler’s childhood moniker.
