In a recent article on The Wilson Journal of Ornithology In-Press, authors  Laura Mahecha, Nickole Villabona, Laura Sierra, David Ocampo, and Oscar Laverde-R. described the Andean Cock-of-the-rock (Rupicola peruvianus) as a frugivorous bird predator.

“Cotingas are considered essentially frugivorous, but a few records suggest they might include small vertebrates in their diet, mainly during the breeding season.”

In March 2015, the authors recorded a young male of an Andean Cock-of-the-rock (Rupicola peruvianus) chasing and eating an adult Canada Warbler (Cardellina canadensis) in Santa Maria, Boyacá (Colombia). The next day, they observed another adult male chasing a Swainson’s Thrush (Catharus ustulatus), but they were unable to observe the end of the chase.

“Observations of hunting small vertebrates suggest this species may be omnivorous, not only during the breeding season but throughout its annual cycle,” they described. “These may be rare cases, but notably both events involved migratory species that may not recognize these colorful birds as possible predators because they are not exposed to cotingas in the temperate zone. Predation on adult birds is difficult to observe in the wild, but this information is essential to better understand the life histories of birds and the different selection pressures acting on them.”
