CONCLUSIONS
Because many diurnal bird species are known to have a variety of calls, and are still considered the same species, or
subspecies, it may be premature to classify owls based on different calls alone as suggested by König & Weick (2008).
It would therefore be useful to employ other taxonomic characters such as physical plumage as well as to DNA barcoding
together with behavioural and ecological attributes as a holistic approach to elucidating the taxonomy of the
genus Otus. It would also be helpful for local birders to pay more attention to the vocalisations of any scops-owl they
encounter in field as well as its plumage, and to study the behaviour and ecology, so as to better understand these
