The most (and probably) endangered chachalaca species was rediscovered in Eastern Brazil: Ortalis r

This is what the study "Ortalis remota: a forgotten and critically endangered species of chachalaca(Galliformes: Cracidae) from Eastern Brazil" tells about this rediscovered species. Much is known about the destructive process caused by humans in the remaining semideciduous Atlantic forest and Cerrado in countryside São Paulo State that encompasses the actual distribution of O. remota. An old history of disturbance caused by the expansion of pastures and livestock, monoculture plantations (currently, sugarcane and soybeans), construction of dams, and urbanization associated with a ‘hoodwinking’ attitude towards Brazilian environmental laws are current threats to the biodiversity of the region. A proper estimation of the species’ geographic distribution and abundance is urgently needed to classify its degree of threat. Despite any controversy on its taxonomic status, O. remota was recently declared as a Critically Endangered taxon in the Red Lists of Brazil (MMA 2014) and São Paulo State. For these reasons, and in a second step, conservation measures such as restoration of native habitats and connection of vegetation fragments using ecological corridors are needed. Regarding ecological functions, the disappearance of O. remota, will potentially lead to losses in terms of seed dispersal and plant recruitment, since part of the diet of chachalaca species is composed of a variety of fruits.
