A team of researchers from Universidad de Buenos Aires, Museo Argentino de Ciencias Naturales and the University of Münster accurately estimated the size of a white-tipped plantcutter bird by studying nothing but its song. In their paper published in the journal Physical Review Letters, the group describes their study of the unique bird and is raspy cry.
The white-tipped plantcutter is a songbird found in the scrub and woodlands of south-central and south-eastern South America. It is a member of the Cotingidae family, is sexually dimorphic and eats mostly leaves. What makes it truly unique, however, is how it produces its songs.
