Scaniacypselus

Scaniacypselus is an extinct genus of basal swifts from the Eocene of Denmark, Germany and France. Many well preserved specimens still showing plumage were discovered in the Messel Pit near Darmstadt, Germany. Species of Scaniacypselus had relatively broader wings than modern swifts and hindlimbs better adapted to perching on tree-branches, indicating that the bird was not as aerial as its extant relatives and likely nested in trees like hummingbirds and treeswifts. Two species are recognized, S. wardi and S. szarskii.
