Houbara Bustard (Chlamydotis undulata) Science Article 1 abstract In order to define the features that determine breeding habitat suitability forthe Houbara Bustard (Chlamydotis undulata macqueenii), a study of nest-site selection by this species was carriedout in Mori, Xinjiang, China during the breeding seasons in April-June 1998-2000. Most habitats chosenfor nest sites were open areas with […]

Human activities affect the potential distribution of the Houbara Bustard Chlamydotis undulata undulata
Houbara Bustard (Chlamydotis undulata) Science Article 3 abstract Human activities have been reported to impinge on the distribution of the endangered Houbara Bustard Chlamydotis undulata undulata. The present study intends to investigate spatial relationships between Bustard and pastoral distribution in order to identify avoidance patterns and potential exclusions of the species from still-suitable grounds.The study […]
Seasonal variation in Great Bustard Otis tarda diet in South Portugal with a focus on the animal component
Great Bustard (Otis tarda) Science Article 7 abstract The few studies available on Great Bustarddiet were carried out in Spain (Palacios et al.,1975; Lucio, 1985; Caballero, 2002) and EasternEurope (see Cramp & Simmons, 1980) andwere based on stomach analysis. Even fewerdata exist on the seasonal variation in diet composition,as only Lane et al. (1999), usingfaecal […]

The Great Bustard Otis tarda in Morocco: a re-evaluation of its status based on recent survey results
Great Bustard (Otis tarda) Science Article 5 abstract Between 1999 and 2005 five spring censuses of the Great Bustard Otis tarda population in Morocco were carried out, one of which (2003) was finally discarded due to bad weather conditions. Some complementary, partial counts in autumn 2000, winter 2001-2002 and spring 2004 were also carried out. […]

Seasonal population dynamics, nest site selection, sex-ratio and clutch size of the Great Bustard Otis tarda in two adjacent lekking areas.
Great Bustard (Otis tarda) Science Article 3 abstract This paper describes the seasonal variation in Great Bustard Otis tarda numbers in two adjacent lekking areas within Castro Verde, the most important site for this species in Portugal. Furthermore, the first data on the breeding biology of the species in the region are presented. The pattern […]
Mating system of the Houbara Bustard Chlamydotis undulata undulata in eastern Morocco
Great Bustard (Otis tarda) Science Article 6 abstract Among polygynous mating systems, the lekking strategy is recognised when the four following criteria are met: (1) display males aggregate at specific sites; (2) there is no male parental care; (3) the only resource females find at the lek are males
