Concornis is a genus of enantiornithean birds which lived during the early Cretaceous period, in the late Barremian age about 125 million years ago.

This preliminary description was published to record an aspect of the specimen which would be erased upon further preparation: faint traces of wing feathers visible under ultraviolet light.

The legs were fairly long and neither dedicated to perching on branches nor to running on the ground; it had a large hallux as is generally absent in terrestrial birds.

It was found in an aquatic environment, suggesting it occupied at least partly a "shorebird" niche, and given its size would presumably have fed on small invertebrates like insects or crustaceans.

There were terrestrial predators around in its habitat - including its non-avialan theropod relatives and crocodilians - from which Concornis would have found it far easier to fly up to some branch rather than to run away.

The study also found that they were capable of continuous flapping flight, but were likely unable to glide due to having a high body mass to wingspan ratio.
