When you feed birds you get the raptors feeding on the birds that you feed. The small birds disappear as fast as they can. Larger birds, such as this female Downy Woodpecker and the Northern Flicker, stay safe through motionlessness.
Both of theses birds sat so still for at least 3 minutes - not one movement. Then suddenly off they went! Fascinating, isn't it?
Also, note the size difference between the two. Flickers are BIG birds.
