This is more like a bite of frustration. As the Northern flicker chicks get closer to their time to leave the nest, the parents start to reduce their feeding accordingly. In other words, if the chicks are getting all their dinner needs delivered to them then they will not be as gung-ho to spread their wings. So the parents start to reduce their feeding day by day, knowing that a hungry belly is the best incentive to fly. This image captures the moment where the father has given the chick a tiny snack and is preparing to fly off. Sensing this, the chick attempts to thwart its departure by grabbing a beak-full of breast feathers. After they tease their chick in this manner, they proceed to fly to a distant branch and call endlessly to encourage the chick to come get the rest. I spent several weeks documenting a Northern Flickers nest and the full video can be seen here: https://www.derekgrantdigital.com/2-months-in-the-life
