Hubara presence decreasing

Radio Sintonia:

Hubara decreases its presence in Fuerteventura by 59% since 1994.

The hubara bustard is a kind of semi-arid environment that occupies the stony plains, sandy jables and steppe thickets of Fuerteventura, Lanzarote and La Graciosa. The arid and gritty jables, malpaíses and stony of the eastern islands of the Canary Islands constitute the habitat of the Canarian hubara, one of the most unique birds of the Spanish fauna, whose population, threatened by multiple problems, has decreased alarmingly in recent years, as confirmed by SEO/BirdLife studies. It is a species perfectly adapted to the dryness and scarcity of resources of the areas where it lives, the hubara is an omnivorous and very terrestrial bird, whose population is being subject to different conservation and management plans.

 

The abundance of the Canarian hubara bustard has been in the last 30 years greater in Lanzarote than in Fuerteventura, having increased that difference from 1994 to 2011. The average density in the same 12 census localities of Lanzarote sampled in November-December since 1994 tripled from that date until 2011, when the species reached the highest density recorded in the last thirty years, and then abruptly decreased to 4.2 hubaras/km2 in November 2020. In Fuerteventura, the density has been gradually decreasing from 1994 to 2020 in the same 18 census localities, having reduced its workforce by 59% since 1994, with an average density of 0.65 hubaras/km2 in 2020.
According to SEO/BirdLife, the main danger to the species lies in the loss of habitat, caused by the installation of wind farms, golf courses, quarries, linear infrastructures, urbanizations and tourist complexes, as well as by the abandonment of agricultural activities. Due to these factors, the 400 square kilometers of potential habitat for the species estimated in the mid-nineties have been reduced to about 162 in recent years. Also cited as threats are the nuisances derived from tourist visits, military maneuvers and truffle collection, collision with power lines, predation by introduced mammals, pressure from a dense goat herd, illegal hunting and egg collection.
