About 200 Red-breasted geese, which are a globally threatened species have arrived to spend the winter at the Durankulak Lake near Shabla, northeastern Bulgaria. The birds arrived after the mid-winter census of the feathered wetland population, when no red geese were observed.
The reason behind this are said to be climate changes, which are shifting the flight path of the Red-breasted goose. It would continue to come to Bulgaria, but probably for a shorter time, experts say. Years ago flocks of red geese were observed to fly to Bulgaria in November, but lately this happens in mid-January. The largest number of the species was observed in March 2018, when about 30,000 birds landed in the protected area.
