    ABSTRACT
    The bioecology of the Barbary partridge, Alectoris barbara (Bonnaterre, 1792) (Aves Phasianidae) remain less known compared to other Phasianidae species because of the paucity of informations and studies about this species. In this research we studied and compared the breeding success of the Barbay partridge in two protected areas in Algeria. The first indication of the monitoring is the search of nests; this aspect shows the dynamism of population in nature. We have opted for the Mayfield method by using a software (J_test) which is a developed program for MS-DOS to esteem the daily survival of nests between two protected areas (Zeralda and Djelfa). Besides, we have adopted the CONTRAST software to esteem the daily survivals over the years for each region. During 3 years of follow-up, we have found that the size of the average egg in the two protected areas: Zeralda and Djelfa vary between 12 and 13.42 egg/nest. During 2012, we noted that the factor of predation has extremely high rates: on both rock areas between 33% and 56%, respectively for Zeralda and Djelfa during the year. The confrontation of the obtained results for the two methods confirms well that the survival in the areas is not influenced by the ecologic factors that characterizes each protected area. Our results leads us towards the hypothesis of a high biological potential allowing partridge populations, in a semi-arid climate, to be able to turn over and compensate a low survival thanks to some adjustments on the populations density. This information concerning our endemic species allows the researchers to put the first pillars of data and information bank of the Barbary partridge in Algeria.
