Until recently, considered conspecific with Z. chrysops (and both formerly included in Z. viridiflavus), but daytime call a short whistle with an emphasized rise, differing from all other taxa in Z. chrysops in its brevity (score 3), pattern (lower maximum frequency; 3) and emphasis (higher maximum amplitude: ns[3]), and from Z. viridiflavus in its brevity (4) and pattern (different start and end frequencies; 4)#R; also differs in its whiter-grey, less yellow-washed throat (1); grey of breast extending more onto belly (1); marginally whiter lower belly (ns); and grey vs dark reddish iris, but some individual variation recorded (ns). Treatment as separate species supported by DNA evidence#R. Monotypic.
