What the parents are removing is the fecal sac.

Most parents do this regularly after the nest hatches, and as babies grow and thrive. It is something you will see many times per day, as the parents try to keep the nest as clean as they can.

The sacks are generally dropped about 50' from the house as to not attract ground predators such as snakes.
