Description

1. Introduction Bird species richness is an important measure for monitoring biodiversity changes (Andren, 1994; Palmer et al., 2008). Bird community inventories, censuses and surveys provide data of great value for conservation purposes (e.g. Tubelis et al., 2004; Marini and Garcia, 2005; Silva, 1997). For instance, these methods allow the recognition of endemic, threatened, keystone, umbrella or surrogate group of species. Because of their restricted distribution, vulnerability, high influence on other species occurrence or important ecological role in ecosystems, registration of these species might strongly influence priority activities in the protection of the natural environment (Stotz et al., 1996; Silva and Bates 2002, Loyola et al., 2007; Pinto et al., 2008, Piratelli et al., 2008).
