Editing Passerine (section)

==Description==
The order is divided into three suborders, [[Tyranni]] (non-singing, Americas), [[Passeri]] (songbirds), and the [[basal (evolution)|basal]] [[Acanthisitti|New Zealand wrens]].<ref>{{Cite book|title=The Rise of Birds: 225 Million Years of Evolution|last=Chatterjee|first=Sankar|publisher=JHU Press|year=2015|isbn=9781421415901|pages=206–207}}</ref> Oscines have the best control of their [[syrinx (biology)|syrinx]] muscles among birds, producing a wide range of [[Birdsong|songs]] and other vocalizations, though some of them, such as the [[crow]]s, do not sound musical to human beings.  Some, such as the [[lyrebird]], are accomplished mimics.<ref>Winkler, D. W., S. M. Billerman, and I.J. Lovette (2020). Lyrebirds (Menuridae), version 1.0. In Birds of the World (S. M. Billerman, B.

Cornell Lab of Ornithology, Ithaca, New York, US. https://doi.org/10.2173/bow.menuri1.01</ref> The [[New Zealand wren]]s are tiny birds restricted to [[New Zealand]], at least in modern times; they were long placed in Passeri.

Most passerines are smaller than typical members of other avian orders. The heaviest and altogether largest passerines are the [[thick-billed raven]]<ref>Madge, S. (2020).

Cornell Lab of Ornithology, Ithaca, New York, US. https://doi.org/10.2173/bow.thbrav1.01</ref> and the larger races of [[common raven]], each exceeding {{convert|1.5|kg|abbr=on}} and {{convert|70|cm|in|abbr=on}}. The [[superb lyrebird]] and some [[bird-of-paradise|birds-of-paradise]], due to very long tails or tail coverts, are longer overall. The smallest passerine is the [[short-tailed pygmy tyrant]], at {{convert|6.5|cm|in|abbr=on}} and {{convert|4.2|g|abbr=on}}.<ref>Clock, B. (2020).
