Dustribution, status and conservation of the Houbara bustard Chlamydotis undulata Fuertaventurae Rothschild & Hartert, 1894, in the Canary Islands, november-december 1994

Abstract

Distribución, estatus y conservación de la Avutarda Hubara Chlamydotis undulata fuertaventurae Rothschild & Hartert, 1894, en las islas Canarias (noviembre-diciembre 1994). En el presente trabajo se presentan los resultados de un censo que cubre por primera vez toda el área de distribución de la Avutarda Hubara Canaria. Se detectaron hubaras en Fuerteventura, Lanzarote y Graciosa, contabilizándose un total de 379 ejemplares, 33 desde vehículos, 16 fuera de los transectos y un mínimo de 330 dentro de los transectos. Se ha estimado una población global constituida por 527 aves: 18 en Graciosa, 268 en Lanzarote y 241 en Fuerteventura. Probablemente, la densidad de aves registrada en la población canaria es la más elevada que se conoce para la especie. No obstante, la degradación y la destrucción del hábitat amenazan seriamente la conservación de esta subespecie insular.

Distribution, status and conservation of the Houbara Bustard Chlamydotis undulata fuertaventurae Rothschild & Hurtert, 1894, in the Canary Islands, November-December 1994. This paper presents the results of census of the Canarian Houbara, which for the first time the total area occupied by this subspecies, Houbaras were detected only in Fuerteventura, Lanzarote and Graciosa. A total of 379 birds were recorded (33 from vehicles, 16 outside the transects, and a minimum of 330 inside the censusing belt), from which we estimated a total population of 527 birds: 18 in Graciosa, 268 in Lanzarote and 241 in Fuerteventura. Although the species scems to reach in the Canarian archipelago the highest density recorded for its whole geographical distribution, this island population is threathened by current loss and alteration of their habitat.

We are very grateful to K. W. Emmerson (Ornistudio S. L.) for his information on previous censuses, and to P. Jordano for his statistical assistance. Jacinto Barquín helped us with the mapping programs. D. Brooks revised and improved an early draft of the manuscript. We also thank the Instituto Nacional de Meteorología (Canarias Orientales). This work was supported by the Viceconsejería de Medio Ambiente of the Canary Island government.
