Re: Bird (Dinosaur?) vision
<<Is it true that some birds can see only movement -- that they cannot "see"
something that is not moving?>>
They manage to locate our fly-in snack bar in the winter, and that's nailed
securely to a fence. Thick tree branches are also prone to long periods of
motionless meditation. Birds land on them, rather than fly straight into
them. A method of discouraging birds from going near shiny new buildings,
is to stick silhouettes of vicious birds of prey on the windows. There's
also a stationary device sometimes used for scaring crows from fields and
gardens, but I forget the name.
In short, I have my doubts about this.
