Hi Lorrain,
 
I expect you already have the reference for the Leicester eagle:
 
Baxter, I.L. 1993. An eagle, Haliaeetus albicilla (L.), skull from Roman Leicester, England, with some speculations concerning the palaeoecology of the Soar valley. Circaea 10(1): 31-37.
 
The only other one that I have seen was a claw bone from a Middle Iron Age site at Great Abingdon.
 
Best wishes,
 
Ian
