The Balkan Warbler (aka Eastern Bonelli's Warbler) Phylloscopus orientalis, is not a very common sight in southern Greece. In fact, it was very rarily seen in the past. However, in the last two or three years sightings have become more common. It is not known whether this is due to the presence of more observers in the field, or the increase of the population. So far, individuals in Attica have been seen in Mt Hymmetus, Vravrona Wetland, even Tritsis Park in Athens!
