A large flock of numerous small, dark birds, likely swifts, fills a bright, lightly clouded sky, flying erratically yet cohesively. In the foreground, the tops of green trees are visible, and power lines stretch horizontally across the lower part of the frame. To the right, a tall, light-colored apartment building with several antennas and dishes on its roof stands prominently. Below and to the left of this building, other apartment blocks of varying heights are seen. The scene depicts an urban or suburban environment during what appears to be daytime, possibly late afternoon. The ambient audio features the distinctive, high-pitched screeching and twittering calls of the birds. No visible text is present.
