Colour marking of ravens in "Vrachanski Balkan" Nature park01.11.2016
More than 1000 Ravens (Corvus corax) have been ringed in “Vrachanski Balkan” Nature Park (NW Bulgaria) within the last four years by Georgi Stoyanov from the Birds of Prey Protection Society.
Most of them have been individually marked by colour rings (red colour, white symbols) or combinations of metal rings. Please share among birdwatchers, wildlife photographers, hunters etc. in Bulgaria and other Balkan countries in order to keep an eye for marked Ravens.
Thanks in advance for submitting the resightings to the Bulgarian Ornithological Centre (IBER – BAS).
