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. The aims were to survey new areas where occurrence of the species was suspected but not confirmed, re-evaluate all recently published counts, establish reliable productivity, sex-ratio, and age structure values, and assess the conservation status of this endangered population.
