Toucans ( Ramphastidae) and hornbills ( Bucerotidae) as ant followers.

Toucans, especially species of the group Ramphastos vitellinus, occasionally follow armies of ants in tropical forests, on the look out for prey disturbed by the ants. Two methods of searching are used: examining the ground or the lianas and trunks. In contrasts, forest hornbills, (white crested hornbill Tropicranus albocristatus), frequently follow ant armies in Africa. After waiting poised in an erect position, they leap forward towards the ground or at the trunk, sometimes reaching up into the leaves.-translated by C.Wilson
