A deceased small passerine bird, likely a Black-and-white Warbler (Mniotilta varia), lies supine on a textured, light grey concrete surface in Mexico City, Mexico. Its plumage features a white breast with distinct dark streaking, a greyish back, and black wings. The head displays a prominent black and white striped pattern, with a dark eye exhibiting a reddish tint and a slightly open beak revealing a pale interior. The feathers appear somewhat ruffled, particularly on the head and chest. Its slender legs are partially visible and appear tangled or injured, extending from the lower abdominal area. A few blades of green grass are present in the upper and lower right portions of the frame. The concrete surface shows minor cracks and dark specks. The scene is illuminated by ambient natural light.
