Collared Forest-Falcon (Micrastur semitorquatus) Preying on Chestnut-mandibled Toucan (Ramphastos swainsonii) in Costa Rica

چکیده
—Predator-prey interactions occur regularly in nature; however, predation events are difficult to observe in the canopy of tropical rain forests. We describe a successful capture of a Chestnut-mandibled Toucan (Ramphastos swainsonii) by a Collared ForestFalcon (Micrastur semitorquatus) in Carara National Park, Costa Rica. The predator-prey interaction lasted for ,30 min from the moment of the first wounding strike in the canopy to the killing of the toucan on the ground. During the predation process, the falcon engaged in multiple attacks from different directions at the sub-canopy level. We video recorded a total of 323.3 sec tracks during the predation event to produce a 1 The School for Field Studies, Apartado Postal 150-4013, Atenas, Alajuela, Costa Rica. 2 Escuela de Biologı́a, Universidad de Costa Rica, San Pedro Montes de Oca, San José, Costa Rica. 3 Corresponding author; e-mail: [email protected] 212 THE WILSON JOURNAL OF ORNITHOLOGY N Vol. 125, No. 1, March 2013

Figs and the Persistence of Toco Toucan (ramphastos Toco) at Dry Forests from Western Brazil
– The Toco Toucan (Ramphastos toco) is a large canopy frugivore common in the seasonal areas of the interior of Brazil. In this study, I evaluated fruit production and analyzed the toucan’s feeding habits in two types of dry forests, one deciduous, although rich in figs, and another semi-deciduous, both in the western Brazil. Both areas exhibited marked fruiting patterns, which peaks overlapped...

The structure and mechanical behavior of Toco Toucan (Ramphastos toco) and Wreathed Hornbill (Rhyticeros undulatus) beaks were compared. The beak of both species is a sandwich-structured composite, having an exterior, or rhamphotheca, consisting of multiple layers of keratin scales and a core composed of a fibrous network of bony closed-cell foam. The rhamphotheca is an arrangement of approxima...
متن کاملEvolutionary history of Ramphastos toucans: molecular phylogenetics, temporal diversification, and biogeography.
The toucan genus Ramphastos (Piciformes: Ramphastidae) has been a model in the formulation of Neotropical paleobiogeographic hypotheses. Weckstein (2005) reported on the phylogenetic history of this genus based on three mitochondrial genes, but some relationships were weakly supported and one of the subspecies of R. vitellinus (citreolaemus) was unsampled. This study expands on Weckstein (2005)...
