Hirundo rustica (Linneaus 1758) is the extant barn swallow. Swallows are not related to, but convergent with swifts like Apus. Here they nest with wrens and dippers, but with a shorter rostrum/larger orbit and longer wing feathers.

Cinclus cinclus (Linneaus 1758 (Sturnus cinclus); Borkhausen 1797; 18 cm long) is the extant white-throated dipper. Its short wings whirr swiftly and without pauses or glides. From a perch it will walk into the water and deliberately submerge. It 'flies' underwater. Prey includes aquatic invertebrates. Sister clade includes the wrens,Troglodytes.
