Alpine and Common Swifts on a Mountain Rock — Postcard

A dark common swift and a larger, white-bellied Alpine swift cling to a rocky outcrop, while two more swifts cut across the sky above snow-capped peaks. The illustration is based on Johann Friedrich Naumann's 19th-century scientific bird plates. A striking choice for mountain-lovers or a postcrossing swap with an alpine theme.
