It was formerly placed in the genus Myrmotherula. It is found in Brazil, Colombia, Ecuador, and Peru. Its natural habitat is subtropical or tropical moist lowland forests. TaxonomyThe rufous-tailed antwren was described and illustrated by the English zoologist Philip Sclater in 1890 and given the binomial name Hypocnemis erythrura.[2] The current genus Epinecrophylla was erected in 2006.[3] Two subspecies are recognized:[4]
DescriptionThe rufous-tailed antwren is about {{convert|11.5|cm|in|1|abbr=on}} in length and has a slightly longer tail than other members of the genus. The male has olive-brown upper parts with a chestnut back and tail, and pale tips to the wing coverts. The throat and breast are grey, sometimes with a dark "scaled" effect, and the belly is olive brown. The female is similar but the throat and breast are buff-ochre and the belly dull brown. In both sexes, the iris is red or orange and the bill is dark. The male is the only member of the genus without a contrasting throat patch. The female is similar in appearance to the stipple-throated antwren (Epinecrophylla haematonota), but that has no chestnut on its back. The song is a high-pitched, rather squeaky series of notes.[5] DistributionThe rufous-tailed antwren is endemic to the moist tropical forests of northern South America. Its range includes western Brazil, southeastern Colombia, eastern Ecuador and eastern Peru. This bird occurs in the lower and middle storeys of the forest at altitudes of up to {{convert|700|m|ft|-2|abbr=on}}.[5] EcologyThe rufous-tailed antwren often feeds in pairs or small groups, often joining mixed flocks of small birds flitting through the lower parts of the canopy, often foraging higher in the trees than other related species.[5] The diet consists of insects and spiders, most of which are found by probing into rolled-up leaves. The nest is a dome-shaped construction with a side-entrance; breeding takes place in February in Ecuador.[6] StatusThe rufous-tailed antwren is a fairly common species with a very wide range. The population appears to be stable and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".[1] References1. ^1 {{IUCN|id=22701494 |title=Epinecrophylla erythrura |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} {{Taxonbar|from=Q1261956}}{{DEFAULTSORT:antwren, rufous-tailed}}2. ^{{ cite book | last=Sclater | first=Philip L. | author-link=Philip Sclater | year=1890 | title=Catalogue of the Birds in the British Museum | volume=15 | place=London | publisher=British Museum | pages=230, 236, Plate 15 | url=https://biodiversitylibrary.org/page/8326066 }} 3. ^{{cite journal | last1=Isler | first1=M.L. | last2=Lacerda | first2=D.R. | last3=Isler | first3=P.R. | last4=Hackett | first4=S.J. | last5=Rosenberg | first5=K.V. | last6=Brumfield | first6=R.T. | year=2006 | title=Epinecrophylla, a new genus of antwrens (Aves: Passeriformes: Thamnophilidae) | journal=Proceedings of the Biological Society of Washington | volume=119 | issue=4 | pages=522–527 | doi=10.2988/0006-324X(2006)119[522:EANGOA]2.0.CO;2 | url=http://www.museum.lsu.edu/brumfield/pubs/Isleretal2006.pdf | deadurl=yes | archiveurl=https://web.archive.org/web/20100629234312/http://www.museum.lsu.edu/brumfield/pubs/isleretal2006.pdf | archivedate=2010-06-29 | df= }} 4. ^{{cite web| editor1-last=Gill | editor1-first=Frank | editor1-link=Frank Gill (ornithologist) | editor2-last=Donsker | editor2-first=David | year=2018 | title=Antbirds | work=World Bird List Version 8.1 | url=http://www.worldbirdnames.org/bow/antbirds/ | publisher=International Ornithologists' Union | accessdate=23 February 2018 }} 5. ^1 2 {{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=PA143 |year=2009 |publisher=University of Texas Press|isbn=978-0-292-71748-0 |page=343}} 6. ^{{cite web |url=http://www.hbw.com/node/56728 |title=Rufous-tailed Antwren (Myrmotherula erythrura) |author=Zimmer, K |author2=Isler, M.L. |date= |work=Handbook of the Birds of the World Alive |publisher=Lynx Edicions, Barcelona |accessdate=30 July 2016}} 7 : Epinecrophylla|Birds of the Amazon Basin|Birds of the Colombian Amazon|Birds of the Ecuadorian Amazon|Birds of the Peruvian Amazon|Birds described in 1890|Taxonomy articles created by Polbot |
