Abstract Field studies of natural selection have been carried out on both polymorphic and quantitative characters. Although the latter are more common in nature, above the molecular level, population geneticists have until recently concentrated on polymorphic variation for both technical and theoretical reasons (Endler 1986).

Abstract People identify birds using several characteristics at once-size, shape, plumage pattern and color, attitude, voice, habitat, locality, and so on. All may be important, but size and plumage color are regularly noted by most observers, and if only one characteristic were to be employed, color might be the most useful.
