Résumé :

Finsch's Wheatear, Oenathe finschii, is a widespread winter visitor in Jordan, primarily in arid - semi arid hilly areas with a mean annual rainfall of 100-300 mm. The average territory size in winter varied among the different study areas from 1.6 to 3.4 ha. This variation was not related to productivity and food density, but may have been caused by differences in habitat structure and interspecific territoriality by the Mourning Wheatear, Oenanthe lugens, which was present in half of the study areas. Territory size variations were not sex-related although females were apparently excluded from more productive habitats by dominant males.
