Research has shown that [[unary coding]] is used in the neural circuits responsible for [[birdsong]] production.<ref>{{cite book|editor1-last=Squire|editor1-first=L.|editor2-last=Albright|editor2-first=T.|editor3-last=Bloom|editor3-first=F.|editor4-last=Gage|editor4-first=F.|editor5-last=Spitzer|editor5-first=N.|title=Neural network models of birdsong production, learning, and coding|date=October 2007|publisher=Elservier|location=New Encyclopedia of Neuroscience|url=https://clm.utexas.edu/fietelab/Papers/birdsong_review_topost.pdf|access-date=12 April 2015|archive-url=https://web.archive.org/web/20150412190625/https://clm.utexas.edu/fietelab/Papers/birdsong_review_topost.pdf|archive-date=2015-04-12}}</ref><ref>{{cite journal | last1 = Moore | first1 = J.M. | display-authors = etal | year = 2011| title = Motor pathway convergence predicts syllable repertoire size in oscine birds | journal = Proc.

Another contributing factor could be that unary coding provides a certain degree of error correction.<ref>{{cite arXiv|eprint=1411.7406|title=Error Correction Capacity of Unary Coding|first=Pushpa Sree|last=Potluri|date=26 November 2014|class=cs.IT}}</ref>
