Recurve-billed Bushbirds
Antbird Information … Antbird Species
The Recurve-billed Bushbird (Clytoctantes alixii) is a Thamnophilid Antbird that inhabits dense stands of secondary vegetation at the northern end of the Andes in Colombia and Venezuela. It inhabits well-developed secondary growth at 150-1750 m.
Until recently, the bird was almost unknown in life: apart from earlier specimens, it had been seen only once at an army ant swarm in Colombia in 1965 (1,2). A significant effort in Colombia failed to find the bird. However, in April 2004 the species was found in Venezuela in the foothills of Sierra de Perijá close to the border with Colombia (3, 4), during a Conservation International-financed Rapid Assessment (RAP) expedition consisting of ornithologists Miguel Lentino, Jorge Perez-Eman, Irving Carreño and Chris Sharpe working under the auspices of the Venezuela Audubon Society and the Phelps Ornithological Collection. The first photographs were taken of a pair of birds. Four months later the first sound recordings were made and behavioral notes were taken by British ornithologist Chris Sharpe.
Working in parallel, Colombian ornithology student Oscar Laverde found Bushbirds in Norte de Santander, Colombia in July 2005. The birds were subsequently studied in detail by Laverde, F. Gary Stiles, and ornithology students of the Natural Sciences Institute of the National University of Colombia. Their findings are published in issue No. 5 of Ornitología Colombiana.
Description
The Bushbird is 16.5 cm (6.5 inches) long and unmistakable. It is named for its extraordinary bill, which curves upwards. The male is slate gray, the female rufescent brown.
Diet / Feeding
It is insectivorous and a bamboo specialist.
Status
The outlook for the Bushbird in the foothills of Sierra de Perijá in Venezuela seems positive, and certainly much better than scientists had guessed before 2004. The bird appears to be not uncommon in regenerating swidden (“slash-and-burn”) plots.
A significant area of extremely important, uninhabited primary forest is being rapidly invaded in the foothills of this range where the forest is being felled to plant short-term cash crops. There appears to be little attempt to control or regulate illegal deforestation there by the Venezuelan government and local political support for the invasion. Despite the long-term consequences for the survival of the forest and its species, in the short term this may lead to creation of further Bushbird habitat.
The Bushbird should now be looked for in suitable area elsewhere. Sierra de Perijá is one of the top conservation priorities for birds in Venezuela, not just for this species but for several other threatened birds.
