The method for determining the age of the White-Tailed Eagle (Haliaeetus albicilla) nestlings was proposed. This method is based on photo tables made on the basis of stop-frames of web cameras installed on the nests of White-Tailed Eagles in Estonia, Latvia and Russia. The method will be useful for researchers who monitor the nests by remote methods, for example using drones.
