Since 2004 we have been studying several groups of
urban black-tufted marmosets (C. penicillata) in different
areas of the city of Belo Horizonte, Minas Gerais, Brazil. Belo
Horizonte is the capital city of Minas Gerais state, home to
more than two million human inhabitants and is situated
in the transition zone between the two Brazilian biodiversity
hotspots (the Atlantic forest and the Brazilian Cerrado
(savannah)) (Goulart et al., 2010). The city of Belo Horizonte
occupies an area of 282 km2; its surface area is 51% covered
by concrete, and the rest of the city’s land-coverage is ‘green
areas’ (i.e., parks, squares consisting of forest fragments and
open savannah type habitat), there are approximately 300
green areas larger than 1 ha (Teixeira, 2009)
