On the status of forest birds in tropical and subtropical South America
In my 40-year study of South American birds, an important focus has always been species preservation. For this reason, when I wrote the paper about the problem that apparently affects forest birds in South America (Nores 2009), I hoped that some researcher would show me that the problem is, at least, not so important as to have a significant impact on bird conservation. So, when I saw a group of 13 researchers from different countries (despite several of them not having experience in tropical forest birds) claim that there is no evidence for widespread bird decline in protected South American forests (Stouffer et al. 2011); I saw this as a positive contribution. However, after reading the commentary, I am afraid that their arguments are insufficient to show that the problem may not be a threat to bird survival.
