I stumbled across Eric Hosking's pictures of owls this evening. Love those eyes and feathers. His most famous image is probably the 1936 image below of an owl with its prey.
This last image is said to be the first time a flash was used to capture a bird in flight, in 1948.
Hosking is apparently the only artist to make a living by taking pictures solely of birds - his reputation initially being made by news coverage of the loss of his left eye after being clawed by a tawny owl. I know it sounds made up, but it isn't (I went beyond wikipedia to make sure).
