Saker falcon (Falco cherrug) is extremely rare bird, which does not nest in Bulgaria, but can only be seen during migration and wintering. The reasons for this are complex, but the most important are his persecution in the past and the loss of hunting and nesting habitats – all causes caused by man. From 2015 NATURE SCIENCE Foundation jointly with the Institute of Biodiversity and Ecosystem Research and Plamen Paskalev (Member of the Management Board of the Bulgarian Sokolary Union) started a breeding program for hawkers in order to protect them in the wilderness. The birds are of European origin, grown in volley conditions, and hatched young Falcons will be returned to nature in Bulgaria. The good news came on March 8, 2016, when one of the three pairs of falcons brought his first egg and a few days later the second breeding pair followed. We expect 9-10 tiny falcons to hatch after about a month.
