Given the strong relationship between the birds and the environments where they live, this study aimed to characterize the temporal dynamics of molts, breeding, abundance and vocalizations of Pseusoseisura cristata, as well as the influence of climatic periods under these aspects. Data collection was monthly between June 2011 and May 2012. The Caatinga area studied is located in the municipality of São José do Egito, Pernambuco - Brazil. Nine mist nets were used to capture and record brood patch and molts. The sampling effort was equal to 3564 hours/net. The abundance was estimated through three "strip transects" and the temporal structure of vocalizations were recorded through sound contacts with unlimited radius. It was verified that the climatic periods influence the molts and breeding. Both occur during the rainy season, since they require a large supply of resources to meet the energy demands of the processes. The seasonality also exerts a subtle influence on the temporal structure of vocalizations, forming different patterns for the dry and rainy seasons. However, these patterns must be further linked to breeding the rainfall itself. The abundance in turn, was not altered as a function of climate, revealed that this species is better adapted to climatic variations of the environment.
