Reporting escaped bird of prey sighting

Does anyone know where you should report a sighting of what looks like a missing bird of prey?

My dad has seen what he thinks is a Harris' hawk with a jess on its leg.

 

Check the local bird of prey centres if not one from them then call RSPB to alert them.

 

there is a weekly paper cage and aviary birds try them as well

 

Hi there,

If you contact the Independent Bird Register, they'll be able to help Falconry equipment - falconry equipment online - cheap bird vitamins

 

Thanks everyone, I will pass that on
