Xavi Bou - Ornitographies
Photograph: Xavi Bou01Last December, Xavi Bou captured starling murmurations in northern Spain for his continuing series *Ornitographies.*

Photograph: Xavi Bou03Murmurations can contain millions of birds. 
Photograph: Xavi Bou04Murmurations are so named because of the low, fluttering sounds the birds' wings make.
Photograph: Xavi Bou05The birds move in astounding unison, with each mimicking the movements of six or seven neighbors.
