Additional remarks. The new subspecies is clearly a transition between S. a. aurantiirostris, with which it intergrades to the north (Fig. 1). and S. maxillosus. In common with S. a. aurantiirostris, S. a. parkesi males exhibit a black breast band and black malar and auricular regions, while the eyebrow of both sexes extends back almost to the nape. 5. a. parkesi is similar to S. maxillosus in the colouration of the underparts and the complete lack of white patches on the terminal portion of the outer rectrices. On average, the wings and tail of S. a. parkesi are larger than those of S. a. aurantiirostris (see Table 1). In comparison with S. maxillosus, the females of the new subspecies have shorter wings and tail, while the males have a larger bill. S. a. aurantiirostris has shorter wings and tail than S. maxillosus (Table 1)..
