—Rock-Balancing Demo: On Sunday, Aug. 28, 11 a.m. to 12:30 p.m., "Center of Gravity" photographer and balanced-rock sculptor Peter Juhl will demonstrate his rock-balancing skills. No glue, magnets or artificial supports are used in creating these gravity-defying sculptures—some of which only last long enough for a photo to be snapped. Visitors can check out the exhibit while watching the balancing act. Arboretum Restaurant Gallery.

Arb naturalist Matt Schuth reports that warbler migration is happening: Twelve species have been reported, including mourning, Wilson's, pine, black-throated green, golden-winged, Northern waterthrush and blackburnian.
In other bird news: Many hummingbirds are feeding on jewelweed along the boardwalk (where flowers in bloom now—along both Green Heron Trail and boardwalk—include white snakeroot, purple-leaved willow herb, white flat-topped aster, New England aster, green-headed coneflower, blue vervain, wild cucumber).
We're seeing many least skipper butterflies. The meadow katydid is singing, and a brood of Eastern phoebes are calling at the bridge below the waterfall.
