Aviraptor

Aviraptor is an extinct genus of small accipitrid bird of prey known from the Oligocene of Poland.

It was named in 2020 by Gerald Mayr and Jørn Hurum based on a single nearly complete specimen.

[1] Aviraptor closely resembles modern hawks of the genus Accipiter in overall size and proportions.

Aviraptor was very small for a bird of prey, with a body size similar to the modern tiny hawk Accipiter superciliosus and little sparrowhawk A. minullus.

Furthermore, Aviraptor differs from Accipiter in anatomical details such as the proportions of its second toe and the shape of the deltopectoral crest of the humerus.
