About 30-40 minutes before sunset, birds arrive to this tree, sit for a while, flu away and return back, and repeat these maneuvers several times. Sometimes it's just starlings, sometimes it's sparrows, sometimes it's robins, sometimes it's house finches, sometimes different species together at the same time. Then the whole flock disperses. On the same tree, birds often gather in the morning, just before sunrise.
