Cinnamon Screech-Owl (Megascops petersoni). Field Museum of Natural History, Chicago. FMNH catalogue no. 317314. Lack of knowledge of this species has lead to a risk classification nohigher than 'least concern'. However, this owl's existence has only been known since the early 1980's and very little is known of the population density and population trends within its range in tropical and subtropical montane regions of Colombia, Ecuador and Peru. In addition, not enough is known about its biology and life history. Incomplete knowledge of such speciesresults in a classification that can only go so far in estimating the risk ofextinction. We do not know enough about M. petersoni to ensure its long-term conservation.
