Golden-headed lion tamarin  (Leontopithecus chrysomelas)

Just 2-5 % of the golden-headed lion tamarin's original habitat remains in Brazil (3). This species is now only found in the east of Brazil, in the southern portion of Bahia (2) (3) (7). Here, the majority are confined to the protected Una Biological Reserve (3). They were originally found much more widely across eastern Brazil; today, surviving populations are scattered and thinly distributed (7).

This species inhabits dense primary lowland and high-elevation forest (2). They exploit the forest in the early stages of succession for food but also depend on tall, mature forest for their sleeping holes, which are originally dug out by woodpeckers (5).
