N. ARGENTINA & S. BRAZILIAN GRASSLANDS Biome Endemics and Near-Endemics List 

Birding Site Guide

BENES lists are unique to BSG and were created for the website.


This list contains all species endemic to or difficult to find outside of, this ecoregion. They differ importantly from Endemic Bird Areas because the size of the area they cover is the whole ecoregion, whereas EBA are restricted to 50,000km2, they furthermore not only include all endemic species but also all other species which are difficult to observe outside the individual biomes (this naturally includes near-endemics and any other more widespread threatened or near-threatened species). This was quite deliberately done to provide ready-made lists for birders of all scarce species they could expect to see in the region.
