About the Southern Yellow-billed Hornbill
The southern yellow-billed hornbill (Tockus leucomelas) is a hornbill found in southern Africa. Yellow-billed hornbills feed mainly on the ground, where they forage for seeds, small insects, spiders and scorpions. This hornbill species is a common and widespread resident of dry thornveldt and broad-leafed woodlands. They can often be seen along roads and water courses.
It is a medium-sized bird, 48–60 cm (19–24 in) in length, 132–242 g (0.29–0.53 lb) in weight and is characterized by a long yellow and down-curved beak. This beak is huge in comparison to its body and can account for up 1/6th of the entire body length. Male beaks are on average 90 mm long while female beaks are an average of 74 mm. Males are generally bigger than females but there is overlap between the sexes. The size difference of the beak is a fairly reliable way of differentiating sex in wild hornbills.
The casque that characterizes all hornbills is of a very modest size in the southern yellow-billed hornbill. It is small, but it covers almost the entire length of the beak in males (less so in females), and may give the impression that they do not actually have a casque. As in all hornbills, the...
