What we see here is a bait and switch. You can tell that this is set up because of the range of the camera shot tracking the bird. The bird is clearly lining up to attack as it goes into a glide loop. The camera tracks the approach, the glide path and the attack. First, the eagle has been given bait a couple of times to entice it to come down and make the grab. Maybe the same time of day, but definitely the same spot. This is not random, “oh there’s a kid I’m hungry.” Then the dummy is substituted. When the eagle realizes it is a dummy it drops it. No mother in the world would have put their child out in open, and then not picked up on a bird with an 11 foot wingspan coming in like a dive bomber.
