Summary of Methods: Tewksbury et al. found three main factors that lead to the reduction of riparian avifauna. Loss of deciduous forests, cattle grazing and human encroachment are having the greatest effect on decreasing bird numbers. Cow-bird parasitism was seen to have a positive correlation with human encroachment, but Tewksbury et al. states that it has no correlation with cattle grazing. Cow-bird reduction was emphasized as a major management tool.
