Optical illusion spooks raptors

Researchers have designed a visual pattern that elicits long-term avoidance of high-risk areas by raptors. The scientists’ work clears the way for further investigation into the visual cognition of these birds, and it has applications for conservation, because raptors are among the most common victims of collisions with planes and wind turbines. https://www.sciencedaily.com/releases/2018/10/181011143123.htm
