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
