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.

(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.

Bicolored Hawk (Chilean)
SCI Name: Accipiter bicolor chilensis
chilensis
Chile (formerly spelled Chili). Etymology disputed; probably from Mapuche chilli  ends of the earth.
● Erroneous TL. Chile (= Manila, Philippines) (syn. Lalage nigra).
● Erroneous implied TL. Chile (= Bolivia) (Tangara).
● “Hellmayr is the most recent author who proposes to reject Molina’s name on the grounds that it is a composite between the present form and Jacana j. jacana. It must be remembered that a large percentage of the names of the 18^th century authors are composites, and if any degree of stability in nomenclature is to be attained the name must be fixed on one of the species to which the account applies, provided of course that the name is identifiable at all” (Peters 1934) (Vanellus).
