In the dark part of the roof, the bird gave the egg, there was not enough access to the dense part of the tree. Many times they returned after seeing the egg. I kept looking at it, I thought it was in some interior of the roof. I saw the egg there .... I picked up the egg and nest and placed it in front of the house. With the help of a companion bird he took that egg with a clue and took it somewhere else. I understood that the life of those birds was stuck in the egg, they wanted to get it.
