These are mainly a problem in rural areas where they prey on eggs and chicks of other birds in the springtime. They are often seen singularly looking out for suitable prey off a lofty perch.

Lately a few pairs have started to settle in large towns,

Cheltenham being one such place. They can sometimes be a problem in that they will try to fight their own reflection in glass. This can keep people awake with the noise of pecking at the glass of windows.

Their raucous calls often bother people and they are apt to call very early and quite late also every time they get excited.
