It is found in Bolivia, Colombia, Ecuador, Panama, Peru, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests. SubspeciesFour subspecies are recognised; M. v. villosus from Panama, western Colombia and western Ecuador; M. v. schaeferi from northern Colombia and northwestern Venezuela; M. v. clarus from eastern Ecuador and eastern Peru; and M. v. peruvianus from southeastern Peru and northwestern Bolivia.[2] DescriptionThe tawny-breasted myiobius grows to a length of about {{convert|14|cm|in|1|abbr=on}}. The upper parts are mainly dark olive, and the rump is yellow. There is usually a yellow patch on the crown in males that is normally kept hidden; this patch is cinnamon-brown in females. The underparts are mainly reddish-brown, the throat is dull white and the centre of the belly has a pale yellow patch. The otherwise similar sulphur-rumped myiobius (Myiobius sulphureipygius) has paler upper parts and much yellower underparts, with tawniness only present at the sides. The black-tailed myiobius (Myiobius atricaudus) lacks any tawniness on its underparts, but in any event, these are lowland species,[3] with the tawny-breasted myiobius occurring at higher elevations than the other members of its genus.[4] Distribution and habitatThe species is native to rainforests in the foothills of the mountains of tropical South America. Its range includes Venezuela, Colombia, Panama, Ecuador, Peru and Bolivia. Its altitudinal range extends from {{convert|600|to|2100|m|ft|-2|abbr=on}}.[1] StatusM. villous is generally described as uncommon, and its total population is suspected of declining as its rainforest habitat is destroyed. However it has a very wide range and a presumed large total population, so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".[1]==References== 1. ^1 2 {{cite journal | author = BirdLife International | author-link = BirdLife International | title = Myiobius villosus | journal = IUCN Red List of Threatened Species | volume= 2012 | page = e.T22699717A39087409 | publisher = IUCN | year = 2012 | url = http://www.iucnredlist.org/details/22699717/0 | doi = 10.2305/IUCN.UK.2012-1.RLTS.T22699717A39087409.en | accessdate = 8 July 2016}} {{Taxonbar|from=Q1260704}}{{DEFAULTSORT:myiobius, tawny-breasted}}2. ^{{cite web| editor1-last=Gill | editor1-first=Frank | editor1-link=Frank Gill (ornithologist) | editor2-last=Donsker | editor2-first=David | year=2017 | title=Cotingas, manakins, tityras & becards | work=World Bird List Version 7.3 | url=http://www.worldbirdnames.org/bow/cotingas/ | publisher=International Ornithologists' Union | accessdate=9 January 2018 }} 3. ^{{cite book|author1=Ridgely, Robert S.|author2=Gwynne, John A.|title=A Guide to the Birds of Panama: With Costa Rica, Nicaragua, and Honduras |url=https://books.google.com/books?id=H9INVOMUgOAC&pg=PA297 |year=1989 |publisher=Princeton University Press |isbn=0-691-02512-6 |page=297}} 4. ^{{cite book|author1=Ridgely, Robert S.|author2=Tudor, Guy|title=Field Guide to the Songbirds of South America: The Passerines|url=https://books.google.com/books?id=gC_A2fpBl1gC&pg=PA248 |year=2009 |publisher=University of Texas Press |isbn=978-0-292-71748-0 |page=448}} 4 : Myiobius|Birds of the Northern Andes|Birds described in 1860|Taxonomy articles created by Polbot |
