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.
