Naturalist notes
By late May, fledgling Violet-green Swallows begin testing their wings over the scrubby slopes, chasing insects above the fog line in the long evening light.
Bush lupines finish their bloom in June, and their seed pods dry and twist open audibly on warm afternoons, scattering seed onto the gritty soil.
