DEFINITIONS

COCCYZUS
(Cuculidae; Ϯ Yellow-billed Cuckoo C. americanus) Gr. κοκκυζω kokkuzō  to cry cuckoo  < κοκκυ kokku  cuckoo! the bird’s cry; “Coccyzus, said to be a misprint for Coccygus (Boie, Isis, 1826) as if the genitive of κόκκυζ, κόκκυγος. But it is probably a false latinizing of κοκκύζων = crying “Cuckoo””(BOU 1915); "40. COULICOU, Coccyzus.  Cuculus, Linn. Gm. Lath.  Bec alongé, épais à la base, long, entier, convexe en dessus, arqué, comprimé par les côtés.— Tarses plus longs que le doigt le plus long.— Ailes courtes, arrondies.   Esp. Coucou de la Caroline, Buff." (Vieillot 1816); "Coccyzus Vieillot, Analyse, 1816, p. 28. Type, by monotypy, "Coucou de la Caroline" Buffon = Cuculus americanus Linné." (Peters, 1940, IV, p. 41).
