A University of California researcher named Ken Goldberg has developed a robotic system that will continuously scan the skies for a view of an ivory-billed woodpecker.
The bird was thought to have gone extinct in 1930s but a video in 2004 showed the rare bird.
This bird watching system shoots 2 11-megapixel pictures per second of the sky and discards every picture that does not have any special birds in the view.
On an average the system keeps one picture in every 10,000 that it collects.
Till now the system has captured a red-tailed hawk, a great blue heron and a flock of Canada geese, but till now there is no sign of the ivory-billed woodpecker.
