Chestnut-capped Piha

The chestnut-capped piha is a species of bird in the family Cotingidae. It is endemic to a small portion of Colombia's central Andes in the department of Antioquia. The chestnut-capped piha resides only in a narrow band of humid premontane cloud forest. It is a dark grey passerine with a notable chestnut crown on the upper nape and pale cinnamon-colored undertail coverts. Adults are small for pihas, measuring about 20 to 25 cm long. Males have modified primary feathers with elongated and stiff barbules that enable them to create a whirring noise with their wings, which the piha likely uses for display purposes. Its call is extremely loud and can be heard over 100 m (330 ft) away. The chestnut-capped piha is mostly frugivorous, although it will eat some invertebrates. Little is known about the species' breeding ecology, although it is believed to be a lekking species.
