The range of the curl‐crested jay: lessons for evaluating bird endemism in the South American Cerrado

摘要: The South American Cerrado is the largest tropical savanna of world, and one most threatened biomes on Earth. Levels bird endemism in this biome are controversial, but up-to-date study points to 30 endemic species. In paper, I analysed recent range shift by those species, curl-crested jay Cyanocorax cristatellus, comparing it with three other alleged endemics (lesser nothura Nothura minor, chestnut-capped foliage-gleaner Hylocryptus rectirostris, grey-backed tachuri Polystictus superciliaris) a 'near-endemic' (white-banded tanager Neothraupis fasciata). expanded its considerably into south-eastern Brazil during last century, colonizing extensive areas formerly covered Atlantic forest, which has been almost completely cleared human activity. found no evidence for four species studied, demonstrated that not endemic. vegetation map used previous authors classify birds as imprecise out-of-date, depicting well limits, resulting an arbitrary, sometimes erroneous, classification. suggested adoption more modern detailed map. necessity comprehensive review list Cerrado's light maps highlighted.
