Humans
and birds may be more similar than previously thought

Summary:
A
study of barn owls published in JNeurosci suggests the visual systems of
humans and birds may be more similar than previously thought.
The
ability to perceive an object as distinct from a background is crucial for
species that rely on vision to act on their environment. One way humans achieve
this is by grouping different elements of a scene into "perceptual wholes"
based on the similarity of their motion. This phenomenon has been mostly
studied in primates, leaving open the question of whether such perceptual
grouping represents a fundamental property of visual systems in general.
