Hi Sheila, Yes, according to the size, it could be sooty falcon or Eleonora's (although the occurrence of the latter species would be unusual in UAE, except as visitor or because falconry of course), but what about Barbary falcon (/F. peligrinoides/)? Unfortunately we missed metric database for all these medium-sized falcons. In Solti (1995, Plate XVI, Fig. 1), you can find a single value for the cmc's GL of /F. concolor/ (about 44 mm), very close to your specimen. /F. eleonorae/ and /F. peregrinoides/ might be slightly larger.
