BIRD OF THE WEEK
SÃO PAULO MARSH ANTWREN
SCIENTIFIC NAME: Formicivora paludicola
IUCN STATUS: Critically Endangered
HABITAT: Freshwater marshes in the state of São Paulo, southeastern Brazil
Like many other birds, including the Black Skimmer and Least Tern, the species faces continual challenges by living in proximity to a booming urban population.
The main threat faced by the São Paulo Marsh Antwren is habitat loss, particularly from sand mining, housing developments, and fish farming. Invasive species, including an introduced grass, are also destroying the bird’s already-limited habitat.
