A weathered wooden birdhouse is affixed to the trunk of a large, mature tree under a clear blue sky. The birdhouse, rectangular with a pitched roof, is constructed from unpainted timber, exhibiting discoloration and wear. A rectangular entrance hole is present on its front face, revealing a dark interior. The tree features deeply furrowed bark and dense, dark green, needle-like foliage on its branches, which fill the upper and left portions of the frame. Some sparser branches are visible lower down against the sky. A thin wire is faintly discernible in the upper left background. No individuals or animals are present. The scene is located in Dolni Chiflik, Bulgaria.
