All but one of my Tree Swallows have fledged. The adults are gone. Now there is a House Sparrow building a nest while the other non-fledged Tree Swallow is still in the nest! It seems healthy, but not sure how long he can last. Is there anything I can do or just let nature run its course? Thanks in advance.
