DEFINITIONS

ACCIPITER
(Accipitridae; Ϯ Eurasian Sparrowhawk A. nisus) L. accipiter, accipitris  hawk  < accipere  to grasp (the original meaning was “to understand” rather than “to seize”) (cf. Med. L. accipiter  Sparrowhawk; ancipiter  Goshawk; "another possible origin is from the Greek aci for 'swift' and pertrum [?πτερον] for 'wing'." (Clark & Davies 2018)); "Accipiter. Genus 8.  ...  Les femelles des Oiseaux de ce genre sont plus grandes que leurs mâles. Elles sont aussi mieux faites, plus fortes & plus courageuses. Pour cette raison on appelle les mâles Tiercelets; parce qu'ils sont d'environ un tiers plus petits que leurs femelles.  ...  **1. L'EPERVIER.  ...  ACCIPITER." (Brisson 1760): based on "Accipiter minor" of Gessner 1555, "Accipiter fringillarius" of Gessner 1555, Schwenckfeld 1603, Jonston 1650-1653, and Charleton 1668, "Nisus" of Willughby 1676, and Sibbald 1684, and numerous other references; "Accipiter Brisson, Orn., 1, 1760, p. 28, 310. Type, by tautonymy, Accipiter Brisson = Falco nisus Linné." (Peters, 1931, I, 205).
