The grasslands of Argentina, Bolivia, Brazil, Paraguay, and Uruguay in southern South America represent
important habitat to numerous migratory and resident bird species. These birds play vital roles in the
ecosystem by dispersing seeds and controlling insect populations. Some species, such as the buff-breasted
sandpiper (
Tryngites subruficollis
), migrate some 20,000 km from their breeding grounds along the Arctic coast
to their non-breeding range on the pampas of southern South America. Due to rapid declines, this species is
considered Near-Threatened. Other species, such as the chestnut seedeater (
Sporophila cinnamomea
) and the
saffron-cowled Blackbird (
Xanthopsar flavus
) also cross international borders within southern South America,
and depend on grassland habitat for both breeding and non-breeding activities. Both of these species are
classified as Vulnerable.
