Biologist Measuring Marsh Reeds in Twilight

Indigo twilight blankets the marsh edge near Terni as low-hanging clouds obscure the fading horizon. A biologist clad in olive waders stands knee-deep in still water, extending a metal measuring rod against a cluster of early spring reeds. The reeds, tinged with fresh green shoots and dried brown stalks, sway slightly against the darkening sky. Behind the figure, a portable instrument case rests on a wooden platform, its internal lights glowing faintly amber as equipment warms up. The water reflects the deep blue sky and the warm instrument glow. One reed tip, wet and glistening, droops just above the water's surface near the biologist's boot.
