Yes, that might be a reasonable assumption if the adult was actually delivering food. But we don’t know that to be the case.

As I mentioned, “It’s not known right now … if food was dropped off or not.”

Sadie does visit and tend to the fledglings, but Juno also ‘visits’ the fledglings, sometimes benignly, sometimes aggressively.

In this particular instance, the interaction between the adult and fledgling was not visible from the viewer’s vantage point on the sidewalk (the fledgling was hidden from view behind some of the rooftop equipment) so right now there’s really no way to know which adult it might have been and what occurred during those brief visits.
