The Rock Partridge is found only in Europe in the Alps, Italy and through the Balkans into Greece.

This flock at Sounion in Greece was curious for a number of reasons: It was at sea-level whereas they are normally a mountain bird; it has a fairly large brown streak behind the eye more reminiscent of Chukar Alectoris chukar; and they were surprisingly tame, allowing me to get quite close to photograph them.

I wondered if they could be a hybrid but they were some distance from the hybrid zone in northern Greece.

Sander Bot of the Netherlands comments that they look like Chukars and might have been released as gamebirds.
