Four species of the avian family Cracidae were studied in the Pacaya-S
amiria National Reserve in north-eastern Peru. These large-bodied bird
s are an important source of protein for local communities on the peri
phery of the reserve. An estimated 425 kg of Cracidae biomass were har
vested over a I-year period by three communities. Pipile cumanensis wa
s the most frequently hunted bird, both in terms of individuals hunted
and biomass extracted. Mitu tuberosa and Penelope jaquacu also made u
p a substantial amount of the biomass extracted, but were hunted less
frequently. Densities of all species of Cracidae within 5 km of the vi
llages were substantially lower than in the interior of the reserve. O
ur results suggest that M. tuberosa and P. cumanensis are overharveste
d and P. jaquacu and Ortalis guttata are harvested within the maximum
estimated sustainable levels. In this study hunting grounds were along
waterways and adjacent to protected populations, which created a sour
ce-sink arrangement. If sink areas are overhunted, the unhunted popula
tions inland of the waterways could be acting as source populations th
at replenish overhunted areas.
