Effects of palm heart harvesting on avian frugivores in the Atlantic rain forest of Brazil
This result indicates that Euterpe palms in the lowland forests do not fulfil the role of keystone species, because they bear ripe fruits during the period of peak overall fruit availability and because birds may switch their diets to other food sources when palms are removed.
Aspects of the ecology of Penelope superciliaris temminck, 1815 (Aves: Cracidae) in the Araripe National Forest, Ceará, Brazil.
The data on population parameters and feeding ecology collected in the present study provide an important database for the development of effective management strategies by environmental agencies for the conservation of the populations of the two guan species.
Aspects of the ecology of Penelope superciliaris temminck, 1815 (Aves: Cracidae) in the Araripe National Forest, Ceará, Brazil
Guans are large frugivorous birds that inhabit Neotropical forests and play a fundamental role in seed dispersal and forest regeneration. Despite their ecological importance, the natural populations
Conservation status of parrot populations in an Atlantic rainforest area of southeastern Brazil
Although woodpecker population estimates on the island are large enough to provide nesting sites for parrots, competition for holes with other secondary cavity nesters such as toucans, flycatchers and tytiras, and the selective cutting of dead trees for canoe construction, which is a common practice, may limit hole availability for parrot populations.
Censuses of vertebrates in a Brazilian Atlantic rainforest area : the Paranapiacaba fragment
Between 18 August and 4 September 1998 a census was performed on the guan populations of three areas of the Serra de Paranapiacaba, SE Brazil. The two guan species found the Black-fronted pipingguan

The dominance-predation hypothesis was confirmed for generalist rodent seed predators, but not for specialist insect predators, and shows that density-dependent mortality, not only at the individual level but also at the population-level scale, is a function of the class of predators and their types of foraging behavior.
The local conservation status of the regionally rarest bird species in the state of Rio de Janeiro, southeastern Brazil
We reviewed the local current status and summarized the suspected causes of rarity,  and presumed  major threats to the 84 rarest bird species in the state of Rio de Janeiro, southeastern Brazil . 
Density Estimates of the Black-Fronted Piping Guan in the Brazilian Atlantic Rainforest
Abstract We studied the Black-fronted Piping Guan (Pipile jacutinga), a medium-sized cracid (1.5 kg), endemic of Atlantic rainforest and considered endangered. We present density estimates of
Limitações bióticas afetando o recrutamento da palmeira Euterpe edulis em uma ilha continental da Mata Atlântica
The results show that the drastic reduction of the large frugivorous birds at Anchieta Island do not affect the plant demography, and the herbivory (probably by vertebrates) the main bootleneck for the palmito populaltion in this island.


Conservation of large avian frugivores and the management of Neotropical protected areas
Large frugivorous forest birds are among the most endangered avian groups in the Neotropics. Despite this fact, there has been little field work on members of these groups or on other large
Responses of Amazonian rain forest birds to habitat modification
ABSTIRACI. Bird species were surveyed in a variety of habitat types in a lightly populated airea of western Brazilian Amazonia. Habitats surveyed were unlogged forest, selectively logged forest,
Structure and Organization of an Amazonian Forest Bird Community
To help fill the gap in detailed knowledge of avian community structure in tropical forests, a census of a 97—ha plot of floodplain forest in Amazonian Peru was undertook over a 3—mo period spanning the 1982 breeding season.
The diet of the Scaly-headed Parrot (Pionus maximiliani) was studied during three consecutive years in a 250 ha semideciduous forest in southeastern Brazil. The parrots showed a generalist and
Behavior of Horned Guam (Oreophasis derbianu~) in the El Triunfo Bio- sphere Reserve, Chiapas, Mexico, from February to May in 1982 and 1983, including preen- ing, dustbathing and foraging behavior
Avian dispersal of mimetic seeds of Ormosia lignivalvis by terrestrial granivores : deception or mutualism ?
It is argued that the hard, non-elastic O. lignivalvis seeds, and perhaps a number of other so-called mimetic-seed species, can function as similarly shaped and sized mineral grit universally swallowed by large gallinaceous birds, in that they help to crush and grind the mostly pliable seeds digested by their dispersers.
The Chaco Chachalaca consumed all the fruit species and the rest of the diet consisted of caterpillars and flowers.
