Photo: @Robert Clark. This Ostrich feather is one of my favorite pictures from the Origin of Feathers work that I shot a few years ago.
The feathers of an ostrich are soft and flowing due to the fact that ostrich is a flightless birds. They have no need of the stiff feathers for wind resistance or for gliding purposes. Instead, these soft feathers are used to warm the body or are spread to provide shade for chicks.

I along with other photographers have donated prints in honor of the late photojournalist Chris Hondros who was killed seven years ago. Checkout the link in my bio or the @ChrisHondrosFund feed. #photojournalism
