Nube de estornino en forma de águila durante la puesta del sol - Fotografía de stock

Starling birds murmuration in an cloudy sky during a calm sunset at the end of the day. With a bit of imagination the large group of starlings from the shape of an eagle while they move together in reaction to a bird of prey in the sky. Huge groups of starlings (Sturnidae) in the sky that move in shape-shifting clouds before the night.
