The vocalizations of O. m. ruficeps differ from those of O. m. motmot, but the results should be interpreted with some caution due to the limited sample available for O. m. ruficeps. The main difference of the song of O. m. ruficeps when compared with O. m. motmot is the longer syllable duration (Fig. 3, MANOVA: Taxon F248 = 12.61, p < 0.01), although the duration of each note varied among the two taxa (Appendix 3 and 4).
