The Pliocene Aves in Belgium

The fossil birds collected at Kallo have been described recently by Dyke & Walker (2005).
It is remarkable that the genus Alca, which is now absent from the North Atlantic, was so well represented during the Pliocene in the North Sea basin.
The fauna is similar to the Pliocene avifauna of the Lee Creek Mine, North Carolina, USA.
