Some sexual dimorphisms have been compared with the foraging habits of this species. It has been noted that males and females sometimes differ in foraging habits. Females tend to glean on small branches, while males tend to tap and probe. Evidence of differing bill size shows dimorphism between the sexes in relation to foraging practices. As stated already, it is possible that the physical mechanics that males and females present in foraging, could connect to diverging characteristics in their physiological structure.
