Celericolius acriala

† Celericolius acriala is an extinct bird from the Paleogene or Neogene of the United States, classified as an herbivore. Known from limited fossil material, its systematic position within Aves remains uncertain. Its name references swift or nimble movement ('celer' = swift; 'cola' = dweller). As an herbivorous bird, it likely fed on seeds, berries, or plant matter in Cenozoic North American environments, contributing to an understanding of early avian ecological diversification in the Americas.
