Fledgling swallow demands food from adult swallow. Fledgling swallow was, just before this photo was taken, swooping around catching insects for itself.
What do you think the adult bird did when it landed on the branch next to the fledgling?
Stuffed the insect in its beak down the fledgling's maw.
Ate the insect in front of the fledgling.
Option B. The fledgling did what I presume is the bird equivalent of shrugging and saying, "It was worth a go."
