I noticed that certainly with members of the corvid family, they are attracted to food by sight, especially movement.
A crow will always go for food it sees thrown, rather than food already on the ground, even if it means having to squabble with another bird for it.

Although I seem to remember that the whole "vision is based on movement" came from Jurassic Park and was debunked.
Still, it made me smile to think I was feeding mini-dinosaurs.
