I spotted this bird which had been rather cruelly chained outside a dump with the intention of warding off sea gulls.
No interactions present.
I think this looks like a case for the RSPB. The wildlife crime investigations team contact details can be found at:
at landfill and other waste management sites to drive off gulls and other birds. It's a condition of the standard operating permits that vermin are controlled. Gas guns are of limited efficiency, as the birds get accustomed to them.
Usually, a hawker calls in "on demand" and flies his bird for a while, then goes off to his next call.
I suppose that if the hawk is suitably effective just tethered, rather than flown, this makes life easier for the hawker - less chance of the bird being lost.
But if this site is just tethering the hawk there all day, without expert care, then it is certainly a case for the local police's wildlife officer.
This bird is almost certainly well looked after. Falconers who get these contracts, dote over their birds and give them the highest level of care.
Looks like a young peregrine to me, but falconers often use peregrine x lanner hybrids, so it could be this.
Dark underwing coverts and dark belly suggest a Saker.
Moustachials are far too broad for a saker, but could be peregrine x saker. Really does look very like a peregrine.
