Note Rev. H. B. Tristram's 1859 observation on the Arabic usage of sakqrpage 24 in "Notes on birds observed in southern Palestine" The Ibis vol. 1. "Ta'ir el Hohr, "the noble bird," is the common appellation of the Peregrine and its congeners. "Sakqr" I have only heard applied to the very large falcons — never to the F. peregrinus or F.punicus, both of which are trained by the Arabs for the chase."
