Australian photographer Christian Spencer has lived within Brazil’s Itatiaia National Park for nineteen years. The lush natural surroundings offer a multitude of photo opportunities ranging from pumpkin toadlets to false coral snakes. One of Spencer’s most fascinating finds is the way that light diffracts through the wings of hummingbirds in flight, resulting in a rainbow of colors within the birds’ feathers. The photographer has been following the petite birds for years, and his film recording of the phenomenon was included in his award-winning 2011 short film, The Dance of Time.
