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. […]
