They feed mostly using two methods; one is to perch above the forest floor until prey is spotted, then lunge down to the ground to snatch it; having landed on the ground to snatch a prey item, it will not remain on the forest floor for more than a couple of seconds. The second method used by gnateaters is to glean insects directly from the foliage, trunks, and branches of low vegetation. Typical prey items include
