Dear all, Many thanks for your help. Our modern female specimen has a humerus GL of 104.2mm and our male specimen has a humerus GL of 101.1mm, so perhaps we need more data on bone sizes in more northerly birds as Simon has called for. I will also check the original identification and provenance of our male specimen. The archaeological female goshawk was discarded along with a male sparrow-hawk (based on size) in a 13th c. cesspit at Windsor and I have not ruled out that the latter might have been used for hawking (though perhaps for taking smaller quarry on the whole). I'm aware of the discussions regarding sex of archaeological birds in Prummel (1997) but Cherryson (2002) notes that little data has been published on the sexes of archaeological specimens from medieval England, so it's difficult to know what the female:male ratio would have been generally. Michell (1900) mentions "the use of the trained sparrow hawk, both male and female...".but the discussion focuses on female birds. I have not yet done a survey of new zooarchaeological data so any published or unpublished reports are welcome. Best wishes, Poly Cherryson, A.K., 2002 The identification of archaeological evidence for hawking in medieval England, in Acta zoological cracoviensia, 45: 307-314.

My own female (from the Netherlands) is 102.

However, I have read that sexual dimorphism is pronounced in this species. My measurements are: Humerus GL 103.5mm Bp 20.8mm SC 8.23 mm other humerus SC 8.23mm Ulna Bp 13.0mm Sc 6.0mm Did 11.3mm Can anyone send me comparative measurements from modern reference specimens for both male and female goshawks.
