Predation of geckos by Bucco capensis in Brazilian Amazonia Predation of vertebrates by small (<100 g) is uncommon but known for many Neotropical species8,10,15. Lizards are a common prey of medium to large-sized birds (e.g., falcons and hawks2,5), but there are fewer reports of such predation by smaller forest birds, including canopy and understorey members of the Dendrocolaptidae, Thamnophilidae, Conopophagidae, Tyrannidae and others6,8,9,13,15. Spotted Gecko Gonatodes Figure 2. Spotted Gecko Gonatodes humeralis collected together with Collared humeralis is a small diurnal Puffbird Bucco capensis, Reserva Extrativista do Rio Cajari, Amapá, Brazil, 8 July forest lizard (42 mm, snout–vent 2010; (a) dorsal and (b) ventral views; note the wounds inflicted by the length), common throughout most (Fabio Schunck)
