Himantopus mexicanus (Muller 1776) is the extant black-winged stilt. It is a wading bird with extraordinary long, slender legs, and a descendant of Eocypselus, a hummingbird ancestor. Like the hummingbird, the beak is long and gracile. Stilts probe for buried invertebrates in mudflats near water while hummingbirds probe flowers for nectar.

Eurotrochilus inespectatus (Mayr 2004, Early Oligocene) is an extinct hummingbird, little different than extant Archilochus. The broken sternum appears to be smaller. The radius and ulna are slightly longer and narrower. The femur is more robust and more robust than the tibia. Pedal digit 3 is more robust. Feather imprints surround the fossil bones.
