bird probably has a nest nearby and is hyper aggressive until the little ones fledge
i think you just got to wait it out
when i had Blue Jays (the American kind) nest in my yard i just wore a special hat with lots of metal on it to keep them from hitting me on the head but the smaller birds could take care of themselves because they’re more maneuverable-- i think your smaller birds will come back when the Jays finish
