KLOB>These small "creeper" birds hunt by movement and color
KLOB>contrast, not by pattern recognition.
Cool. As someone with an interest in animal cognition, this
statement is very interesting, as I don't recall seeing the
research that established this. I recall the "What the frog's
eye tells the frog's brain" classic, but frogs are not birds.
"Search image" concepts generate some amount of controversy,
but I did not know that the issue had been settled for birds.
Could you point to a literature review article or something
related in the primary literature?
