There is an area in front of as well as behind this point that will be in focus, the greater the Fstop the more distance that is covered. It is possible F7.1 was sufficient to cover the entire bird. In other words if the mid section of the bird(and not the head) had been focused on, it is possible that both the head and feet would have been in focus. Perhaps not, but focusing on what is closest wastes 1/2 of the well focused distances you have to work with.regards~Bill
