Abstract:

in the cerrado, veredas are linear physiognomies that occur on hydromorphic soil usually along narrow water courses. they often growth on flat terrain or near headwaters. they are characterised by the abundance of buriti palms (mauritia flexuosa) that growth over other trees, numerous shrubs and a dense herbaceous stratum. despite being common landscape elements through the cerrado's extension, the use of veredas by birds has not been examined in detail. this study aimed to review studies of birds and veredas in the cerrado. publications (n = 25) reported the use of veredas by 261 bird species. only 13 of them had aspects of their biology (reproduction and feeding) studied in detail. veredas are poorly used by cerrado's endemic species, but are the major habitat requirement of several species. the richness of bird species found in veredas is increased by their inclusion in the home range of forest, savanna and grassland species. this study also discusses the values of veredas to the regional biodiversity, and the major threats to their conservation inside and outside the system of nature reserves. suggestions for future research on birds and veredas in cerrado also are provided.
