Territorial Agression towards common buzzards

Our resident peregrines are showing extreme territorial aggression towards any common buzzard within sight of the peregrines’ nest or the juveniles. Before 2020, we had no records of this behaviour, although we knew the peregrines in Exeter had brought down 21 buzzards in 190 attacks over a 6-month period. We are now logging attacks seen in the Louth area and would appreciate any information you may have.
