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. Recurve-billed bushbird_sentence_0

It is named for its extraordinary bill, which curves upwards. Recurve-billed bushbird_sentence_1

Until 2007, the bird was almost unknown in life and apart from earlier specimens it had only been seen in life once at an army ant swarm in Colombia in 1965. Recurve-billed bushbird_sentence_2

Discovery and rediscovery Recurve-billed bushbird_section_0

The species was first described in 1870 by Daniel Giraud Elliot from a specimen obtained from the Rio Napo. Recurve-billed bushbird_sentence_3

He named the species after Dr. Edouard Alix (1823–1893) of Paris. Recurve-billed bushbird_sentence_4

A significant effort in Colombia failed to find the bird. Recurve-billed bushbird_sentence_5

However, in April 2004 the species was found in Venezuela in the foothills of Sierra de Perijá close to the border with Colombia, 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. Recurve-billed bushbird_sentence_7

Four months later the first sound recordings were made and behavioral notes taken by British ornithologist Chris Sharpe. Recurve-billed bushbird_sentence_8

Working in parallel, Colombian ornithology student Oscar Laverde rediscovered bushbirds in Norte de Santander, Colombia in July 2005. Recurve-billed bushbird_sentence_9

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. Recurve-billed bushbird_sentence_10

Their findings are published in issue No. Recurve-billed bushbird_sentence_11

They are better located using their call which is made up of four short whistling notes. Recurve-billed bushbird_sentence_13

The first published photos of the species were circulated in June 2007 from images taken by Fundacion ProAves at a new reserve in Colombia to protect this species. Recurve-billed bushbird_sentence_14

Features and conservation status Recurve-billed bushbird_section_1

The bushbird is 16.5 cm (6.5 inches) long and unmistakable. Recurve-billed bushbird_sentence_15

The male is slate gray, the female rufescent brown. Recurve-billed bushbird_sentence_16

It inhabits well-developed secondary growth at 150–1750 m. It is insectivorous and a bamboo specialist. Recurve-billed bushbird_sentence_17

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. Recurve-billed bushbird_sentence_18

The bird appears to be not uncommon in regenerating swidden ("slash-and-burn") plots. Recurve-billed bushbird_sentence_19

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. Recurve-billed bushbird_sentence_20

There appears to be little attempt to control or regulate illegal deforestation there by the Venezuelan government and local political support for the invasion. Recurve-billed bushbird_sentence_21

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. Recurve-billed bushbird_sentence_22

The bushbird should now be looked for in suitable area elsewhere. Recurve-billed bushbird_sentence_23

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. Recurve-billed bushbird_sentence_24
