where did the term dirty bird come from
Jamal Anderson He was well known for his "Dirty Bird" touchdown celebration, in which he flapped his arms as if they were wings and rhythmically bouncing side-to-side in the crowd's direction. The dance has been widely copied; in a press conference Anderson stated: “people break out and do the Dirty Bird in the strangest places.”[2]
Brood parasite Interspecific brood-parasites include the indigobirds, whydahs, and honeyguides in Africa, cowbirds, Old World cuckoos, black-headed ducks, and some New World cuckoos in the Americas. Seven independent origins of obligate interspecific brood parasitism in birds have been proposed. While there is still some controversy over when and how many origins of interspecific brood parasitism have occurred, recent phylogenetic analyses suggest two origins in Passeriformes (once in New World cowbirds: Icteridae, and once in African Finches: Viduidae); three origins in Old World and New World cuckoos (once in Cuculinae, Phaenicophaeinae, and in Neomorphinae-Crotophaginae); a single origin in Old World honeyguides (Indicatoridae); and in a single species of waterfowl, the black-headed duck (Heteronetta atricapilla).[6][7][8]
