Two barn swallows are perched on a horizontal metal bar, positioned in front of a window. The bird on the left is partially obscured by the bird on the right. Both birds have dark blue wings and backs, with light-colored undersides and reddish-brown markings on their throats and faces. The background consists of a dark, possibly wooden structure above the window, and a lighter, overcast sky visible through the glass. Below the window, structural elements of a building or canopy are visible, along with a string with a loop. The scene appears to be outdoors, likely in an urban or suburban setting, given the presence of building structures. This scene is located in Marinka, Bulgaria.
