Thanks, Anne, for clearing that up. It’s much less bizarre that the fledglings, after being old enough fly well, move out of the host territory at dusk to roost, but still fascinating because it’s not clear why they should leave if they are only going back again in the morning. Maybe they don’t know the boundaries, or maybe it’s a bit of exploration, seeking out places where they might feed on their own later on. When they return by day to the host territory, do they continue to be fed by the hosts?
