Abstract
The authors have defined at the order, subfamily, family or genus level the very fragmentary and small-size bird bone material from the three Pliocene-age sites in southern Hungary (Beremend 26, Csarnóta 2 and 4), which is in the collection of the Museum of the Hungarian Institute of Geology and Geophysics. The non-catalogued bone fragments remaining from the already examined material were identified. The number of taxa identified is 26, of which one species is new to science. The new species (Pliogallus csarnotanus n. sp.) belongs to a hitherto disputed genus, which is thus recognised through the newly defined material. Of the rest of the material, only Paleocryptonix hungaricus Jánossy, 1991 and Glaucidium baranensis Kessler, 2010 have been identified to species level, the Gallinula, Porzana, Merops, Garrulus, Nucifraga finds to genus level, while the other 18 taxa have been identified only to subfamily or family level (Perdicinae, Columbidae, Alaudidae, Hirundinidae, Panuridae, Paridae, Sittidae, Certhiidae, Muscicapidae, Turdidae, Sylviidae, Motacillidae, Prunellidae, Laniidae, Sturnidae and Fringillidae), or only to order level (Charadriiformes, Coraciiformes).
