I’d advise against it. The legalities –
The only defence to firing an air weapon beyond the premises is if you can show that the only premises into or across which the missile was fired were premises the occupier of which had consented to the firing of the missile (whether specifically or by way of a general consent).
It is also against the law, in England and Wales, to fire an air rifle within 50 feet of the centre of a highway if this results in someone being injured, interrupted or endangered.
s. 21A The Firearms Act 1968.
People are also under the misapprehension that all birds considered as vermin can be shot at any time and by anyone, which is not entirely true. All birds and animals are protected by law and only “authorised” persons – and I’m assuming the OP isn’t, who have proper permission can lawfully do so.

Maybe use a scarecrow or other visual scarer –
