Trip to Evros Delta, December 2011 (Part 3)

Greylags used to be very common winter visitors in the past. Nowadays, however, they are much less common, being greatly outnumbered by White-fronted. Few tens of birds are seen each year in Evros Delta, in contrast to several thousands of WF. A very small breeding population is found in Prespa Lakes, numbering less than 50 pairs.
