Curious moments of the daily life of the eagle family were filmed. "The male mainly brings the food, and the female warms the young during the day and night. He brings a little more nesting material and she adds green twigs, cleaning the food scraps from the nest as well. The male is also responsible for driving away eagles - intruders, as well as other birds of prey," Angelov told BTA and added: "I often work from great distances - I watch the eagles from three to four kilometers away. The work is in difficult field conditions - in rain, snow, cold. I move on bad dirt roads, but this work is a passion for me".
